FREE ENERGY – 1000 Mile Hydro Generator SAILING Trial – Ep 42 Luckyfish


Hi everyone, on board Luckyfish we try and
be as energy self sufficient as possible, without relying on a gasoline powered generator. This video shows a unique hydrogenerator installation
on our Wharram Tiki 38 catamaran and the performance that we observed over a 1,000 mile sea-trial. The hydrogenerator has proven to be able to
supply all of our energy needs, particularly at night time, when solar is ineffective. If you enjoy our videos and want to help us
make more productions, then for as little as the cost of a cup of coffee per month,
you can become a Patron. And, to all of our existing Patrons, we’d
like to extend our warmest thanks. Now, let’s go to the video. The installation of a Watt & Sea hydrogenerator. We do hope you enjoy it and thank you for
watching. Hi everyone I’m travelling from Clarkes Court
Bay this morning with Herve, supervisor and electronics installer and general expert on
all things electronic at Grenada Marine. To take a look at some installations of Watt
& Sea hydrogenerators on a variety of boats so it promises to be a very interesting morning. Yes, we will go and see a couple of boats
with Watt & Sea hydrogenerators. This is the Mechanic Department, the Systems
Department and the Metal Department. So, this is quite a large catamaran isn’t
it? Lagoon 57 OK. That’s the first decent look I’ve had at one. So, the idea is that you pull on down rope
to deploy it and then there is a lifting rope as well which is this one here. It travels up over the top through a block
there and then up. And on this boat it looks like they have set
it up with a purchase system. Yes, this is a home-made system. A home-made system. And this boat has two Watt & Seas, which I
find a bit surprising actually. I would have thought on a big cat like this
which is probably very energy dependent on a generator. Obviously they don’t like running the generator
if they can avoid it. I have alot of clients that don’t want to
depend on the generator. That means if the generator stops they can
still be comfortable in a place and live with just the natural energy. They don’t have to rush into a marina if the
generator stops. Rush into the marina to fix the generator
and you are breaking all the crew feeling for the vacation. Its not what you dream of when you come and
sail in the Caribbean. That’s very true. So, yeah its a useful back-up or redundancy
in your power supply. It means you can prolong your holiday. Thats got to be a good thing. Herve then took me to see a Watt & Sea that
had sustained some damage. The boat had a beautiful Copper Coat bottom
job, just like Luckyfish. The whole green and environmental and also
just minimises alot of work every year. Its encouraging to see so many boats in the
Caribbean doing the right thing environmentally. As for the Watt & Sea, the two plastic gudgeon
bushings had failed during high winds in the marina, so there wasn’t much to see there. Go back, its only the two plastic parts here
that broke. But, no damage to the water generator. What was it? Impact? You know, impact with an object? I think it was in a marina. The boat went into the pontoon. We had a big big wind, 40 knots wind in the
night. It was around one month ago. And the big big wind in the night and all
the lines got a little loose and this is when it touched the pontoon. I see. But nothing break on Watt & Sea. Just these two plastic parts. Almost sacrificial. Yes, exactly. Herve showed me their office and we made arrangements
to install our 300 Watt unit that had just arrived from France. This is probably a prime piece of Grenadan
waterfront property and it happens to be your office. I find that incredible. What a spot. Glorious. The yard office. Well they don’t have any attendance problems
with this company. Back at Luckyfish, Herve and I had some more
discussion about where to mount the unit. Having double-ended hulls the Wharram was
never going to be a conventional transom mounting. We solved this by selecting a spot under the
forward cockpit. Forward of the starboard engine, and we designed
a bracket that would suit the Wharram. This has proved to be a good safe location
to raise and lower the unit. This stainless steel bracket has been mounted
with rubber backing pads but they might not be necessary. We will know when we do the sea-trial if there
is any vibration into the boat, but from what Herve was saying, we should not expect any
vibration at all. So the uphaul and the downhaul control lines
come up through the deck and around a turning block and then straight across to a winch. Watt & Sea recommend a six to one purchase
on the uphaul and in our case it was easier to solve the uphaul by using a winch that
we have on hand, rather than additional blocks where there really wasnt alot of room in there
to put a six to one purchase. I’d read that the unit only requires servicing
once every two years. Herve explained to me that this was to replace
the prop shaft seal, which in turn protects the bearings from seawater. By doing this every two years we should get
a long life from the bearings. So that was very little, you only had to pull
that about eight inches or 200mm and that has pulled it fully up. And then to release it, its just a matter
of taking the tension off the winch and when the boat is moving through the water, its
likely we will need to pull on the green down haul line to fully extend the leg. OK, well that covers the mechanical side,
what about the electrical side? So, on the electrical side we are down here
in the starboard hull. I’m down here with Dwayne and we are going
to have a quick look at the electrical connections on the starboard battery bank. From the hydrogenerator, yes, we come in,
and we go into the convertor, which is also known as a regulator. So it passes through the convertor, from the
convertor it comes down to our battery bank, but ABYC standard is that we should protect
the cable before the regulator, or the convertor, and before the battery. So, what we did is install two mega fuse holders
using the required fuse of 50 Amps and we installed it right here. Lets have a look at those fuses mate. That’s a pretty solid fuse, 50 Amp right? Yes, its a mega fuse and its durable. And so that cabling is AW6? Yes, its gauge 6 and also gauge 8 based on
the distance. So, we have the gauge 6 and we have the gauge
8 here because the gauge 6 goes to the port side, so we have to upsize the cable and the
gauge 8 which is smaller. That’s because the battery bank is closer. So we use a gauge 8 which is required. It might seem complicated but its an easy
system. Its a safe system. So there is basically protection for the batteries
at every stage of wire. Yes. From the hydrogenerator to the controller
and to the batteries and to the batteries in the other hull. Every linkage is fused. Yes, not only for the battery, but for the
cable most of all. Because if the cable chafed, or make contact,
positive and negative, we don’t want it shorting out and burning through. So we protect it with a fuse. With the hydrogenerator installed and the
other work on the boat finished, it was time to put Luckyfish back into the water and sea-trial
the unit. We will cover all the other boat work in a
future video. We just left Grenada, oh, where did we leave? Clarkes Court Bay Marina and we are motoring
out straight into a 15 knot trade wind, down the channel and then we will be able to turn
to our West and head around the South end of the island shortly. Its very exciting. Everything is working ticketty boo. Engines are running fine. We’ve got three things we want to test on
this little trip. FIrstly the ahhh, we want to keep an eye on
the new lashings, make sure they stand up to it. We will have a look at those when we anchor
tonight in Grand Anse. We want to check the Watt & Sea. We haven’t put it in the water yet. But we want to test, give it a little trial
and make sure its putting out the amps. We will do that when we get sail up very shortly. So Zaya, what does it feel like to be out
sailing again? Great!. You sounded really excited when we first left
the marina. Yeah. Its nice. It was a bit rough coming out but its certainly
settled down nicely now. We’ve got goose winged jib and foresail and
doing what? 6, 7, 8 knots? Yes, 7 now. 7 knots. So, what is it? Day 2. How far did we go on the first day after leaving
Grenada? 176 miles. 176 miles, pretty good. Average 7 knots? Bit over, yeah. That includes leaving the dock and getting
out of the lee of land and all that, so this next run if it holds, could be even better. We will see if the wind holds. Yeah, we will see. But the exciting news is the Watt & Sea. Its buzzed away all night, humming along,
putting out quite alot of amps and we left Grenada with about 60% charge in the starboard
bank, and about the same in the port bank and then all night we ran the radar, the chartplotter,
the tri-colour. There’s probably about 6 amps in those 3 things. Plus the AIS. And then on the port hull we have the two
fridges, one fridge-freezer and a fridge and they are drawing another 5 amps, so there
is probably 10 or 11 amps getting burned last night and the Watt & Sea still managed to
put probably 2.5 amps into both battery banks all night long and charge them up to full
capacity this morning. Pretty impressive. And now the batteries have just sitting there,
topped off all day. They are just on floating and we don’t know
what to do with all the power. We think we might have to start selling it. But its been funny watching it get hit by
weed. We go through the Sargasso weed and it does
a bit of a vibrate for a few minutes. You can feel the hum go through the boat and
you know there is some weed on the leg. But it shakes it off. It just, I don’t know, as the waves rise and
fall up and down the leg they tend to dislodge the weed, so we haven’t had to haul it up
and clear it by hand. So thats been really good. Well its dawn on the 5th day of sailing from
Grenada to the Bahamas and also the 5th day of testing the Watt & Sea hydrogenerator. It really hasn’t had a thoroughly good test
on this trip because we have had quite high boat speeds in the 7 to 9 knot range much
of the time and so the hydro gen has just been pumping out the amps. The batteries have never dropped below 95%
most of the time they have been topped right off and its just been in a floating state,
both battery banks and that’s been running probably 10 to 13 amps of demand from the
2 fridges and the radar, the plotter etc. You know, that side of it, yeah, it performs. The real test though is in the lighter winds
when the boat speeds are down around the 5 knot mark and we were at that sort of range
last night. Over the last, lets say, 10 hours or so and
so its a good opportunity now to check on the state of charge in the batteries. And its good, its heartening to come down
here into the galley/saloon this morning and look at the port side battery bank and see
that they are virtually topped off which is great. I mean, its such a change for this boat to
see the state of electrical power. So, it seems to have done the job. I have got no doubt that the batteries in
the other side are probably the same. I will have a look later. Another 12 hours or so of running the boat
at this sort of speed of about 4.5 to 5.5 knots, that will be the real test. And we will see if it can keep up with this
electrical demand. Alright, until then, cheers. Well this is the starboard hull where the battery bank
is 210 amp hours. It runs most of the nav gear. Yeah, the news is good after a night of quite
light winds and slow sailing speeds 4 to 5 knots, the battery state of charge here is
97% when it is in floating state it will go up to 105% so, virtually topped off and on
the discharge / charge side of the coin, its…, this is running just chartplotter at the moment,
tri colour I’m about to turn off, its about an amp, AIS, what else have we got on up there?
and the Triton gear, so we are probably drawing off this set of batteries about 5 amps currently. Or more. Its just discharging at 0.5 amp but there
is charge going into the other batteries of course. And, there you go, its just flicking between
discharge and charge, so, dont ask me about the intricacies of how the controller works
but ahhh, its interesting to see that the starboard hull bank which I expected, or,
was told, would receive 100% charge first and then the charge would flow to the port
hull bank. Well, that’s not the case. It might be true when the starboard hull bank
gets to a certain state of charge, it may be not 100% though. It may be 90% or 80 or 70%, I really don’t
know. But it is clear that the port hull bank is
receiving significant amount of charge from the hydrogenerator long before the starboard
hull bank is fully charged. So this ammeter is simply reading the charge
that is coming into the starboard hull bank and doesn’t tell us anything about whats going
into the port hull bank, so you are only getting half the story. But, regardless of that, you can read the
states of charge of the batteries and look at it over a period of time and weigh it up
against boat speed and form an impression of the performance of the hydro gen is like. And so far I’m pretty impressed. I mean, normally you wake up on this boat
after a night of sailing, we certainly wouldn’t be running the gear we are running currently,
it would be heavily moderated, turned on and off as we need it and wed still be down to
60 or 50% charge in both hull banks. And then wed be waiting for the sun to do
its trick during the day. So this hydro gen on passage making anyway,
has just turned everything around completely. Its a different state of affairs when you’ve
got more power than you can use. It makes you wonder what you can be doing
with it. Anyway, all good. Cheers. One of the criticisms you hear about hydrogenerators
is the problems with weed getting tangled with the propellers. And, that is certainly a valid criticism. We started encountering Sargasso weed off
the coast of Brazil and it was occurring as these huge ribbons, miles long, just a few
meters wide, but stretching for long distances. Since arriving in the Caribbean we have found
that perhaps those big colonies of Sargasso have broken up into small patches that are
fairly evenly distributed all the way across the route that we’ve just taken. And we are still encountering them here, in
the Southern Bahamas. So, there is certainly a problem for hydrogenerators. What I have noticed with the Watt & Sea is
that generally you will get small pieces of Sargasso that will get tangled around the
leg they will wrap around and more often than not they will just dislodge themselves and
wash away or a larger piece of Sargasso will come along and do the job for you. And just wash the small pieces away. However, occasionally a clump of weed will
sit there for 30 minutes or so and you will get a little bit of vibration through the
boat telling you that there is something on there. And, in the end, frustration leads to wanting
to get it off. Its been pretty straight forward exercise
to dislodge it. I simply release the down haul rope, let the
leg float up to the surface, the propeller just sits there cavitating and the weed just
washes away. And I suppose I have done that, in the last
7 days, a dozen times, maybe 15 times or so. And that’s out of having weed trapped on the
leg, probably at least once every 20 minutes, there is a piece getting on there. So, all in all, not too bad. And, it makes me wonder about the towed type generators,
you know, with a long piece of rope and a prop on the end that spin. I reckon after a few dozen times of hauling
that rope in and getting the weed off the prop you’d quickly get tired of it and probably
give up on the hydrogenerator until got into a weed free area. Its just my personal opinion but, so far the
weed, there doesn’t seem to be an easy solution, but with this particular unit, I guess it
couldn’t be much easier than just raising and then lowering it.

  2. Harold Hofmann says:

    S/V Lucky Fish continues to amaze me. Following her and the crew always make me smile when notified that you have published a video. Thank you

  3. Sea Journey says:

    great video, now you can to electric stove. Will be curious if it degrades out over next year. what is the slowest speed to get any usable amps from it.

  4. JC F says:

    Thanks for the video on the Watt and Sea. I hope to be setting out on my own sailing adventures in the next year or 2 and have wondered what was the best option to compliment the solar cells. I didn't notice if you have a wind generator and if so how do you like it? Thanks in advance.

  5. SV Esprit Libre says:

    Great video guys. When I start more long distance sailing I intend to purchase one of these. Hope you guys are doing well my friend

  6. forrest johnson says:

    You just can't say enough good things about your channel, Boat and Crew are spectacular, Videos are great, Thanks for taking us along on your adventures

  7. Timothy Black says:

    Hydro is so much better than wind on the water. Wind power on the water is annoying and breaks often. Hydro is much more reliable, since the mass of the parts can be large, thus making everything better engineered and resilient.

    Solar + Hydro is enough if you are moving. If you aren't moving, then put in more solar, and more battery. 🙂 Even on a cloudy day you get power from solar.

  8. Mark Gotham says:

    The Hydro Gen's look very efficient…I think you're forgetting "life before them". Possibly mounting some kind of "weed cutter" which is very popular here in the Staes on outboard shafts in swampy areas would be a solution. Enjoying your life ventures….Mark S.F., Ca 😉

  9. SaltyStang says:

    Great video these type's of video's I really enjoy yea don't get me wrong seeing all the beaches the swimming,diving and all that is cool but to see the tech side of sailing is very interesting Be Safe & Have Fun

    Hey Everyone, if you like what Luckyfish is about then do give us a LIKE and SUB and SHARE! this THANK YOU!

  11. Key Topic says:

    Nice job on this description of the "Watt-Sea' – I was wondering when I noticed this on your previous boat tour – very sustainably cool !  What a feeling to have 'too much power' !
    Very impressive and I can imagine it to be an instant hydro-gen on land too.  I would bet your battery life extends now as well. Seems even at anchor in some current – you'll get a decent charge going…
    * In regards to seaweed collecting on that leg – I wonder if you could epoxy a fine cutting blade on it ??
       On your departure I noticed the wave level , and then ha –  I see your glass sitting on the ttable – – No tricks there – no magnets !??   This why I love catamarans or Tri's  !

    Nice vid – thanks again you guys  !

  12. Charles Thomas says:

    Very informative! I've been thinking about getting a drag behind generator but I didn't actually know anyone who had used one. Since I don't have a cat, it would be mounted aft. Thanks a million for this video. I believe I'll get one.

  13. Alapiko ma Mālolonui says:

    Let's see:
    * Energy from the sun: check
    * Energy from the water: check
    * Energy from the wind: workin' on it?
    * Energy in-a-box: check (MORE batteries desirable? Convert energy to alcohol via still?)
    (.. alcohol to use as fuel, and social lubricant)
    * Food from the sea: check
    * Food in storage (frozen): check (thanks to "excess" electrical juice)
    * Food in storage (can/vacuumBag/freezeDry): can you can or "room temp" store food?
    * Oxygen: check,.. this is NOT space
    * Water from the sky/sea: check,.. watermaker? raincatcher? fish-juicer?

    Doin' PRETTY well on your way to self-sufficiency! I'm takin' notes. 🙂

    ..all we need is some non-petrol non-wind method of propulsion. Big sculling oars (yuloh)?

    Wouldn't some method to exploit "wave power" be nifty? Some sort of inertial mass "automatic watch winder" thingie that you place on the "swingy-est" part of the boat that drives a high efficiency generator. You could call it the "Sea Sick Gen", or the "Pukelectic Dynamo". Hmmm,.. I shall think on this one.

    Now, if we could just figure a way to stifle or reverse corrosion due to salt water!

    ..and I'll get around to more sea shanties,.. eventually. 🙂

    Aloha a mahalo nui ʻolua!

  14. Eric Vialla says:

    really informatics really good

  15. Eric Vialla says:

    you do have a logo on boat …????

  16. Michael Kerr says:

    Is it really worth the 4300 dollars ?

  17. David H. says:

    Really enjoyed this video thanks. I am wondering why the designers of this product do not angle the leg to allow weed to just slide off? Will the current whilst anchored be sufficient to provide any electrical current at all? Thanks for your series.

  18. Laurent Froggy says:

    After the boat tours, the gen. tour. That was super interesting and informative. Many thanks for sharing and best from HKG

  19. Joe Bloggs says:

    Thank you for your test and review on the "watt and sea" gen. I have 900w solar and a 400w (max) wind gen. I want to increase my input power out side of daylight hours and have been considering a second wind gen. or a hydro gen. I noticed corrosion on the join between the prop hub and down shaft of the "watt and sea" gen. mounted on the Lagoon 570.
    So the quality of build of this generator is a concern, along with weed 'maintenance' and impact risks with this type of generator has determined my choice of a second wind generator, where at sea or at anchor (when there's a little breeze) I can be receiving a charge.

  20. Bob Down says:

    Stew, I see further down the comments that you mention that there are three options on the prop diameter.
    Are the 2 other size options included in the initial purchase price, or are they an added extra cost?
    Also do you carry a spare prop in your preferred size?


    after 20 minutes still no price..? what did it cost in grenada//?

  22. Lukáš Smiga says:

    An awesome piece of technology this Watt & Sea hydro–generator. Thanks for sharing a nice testimonial video!

  23. wardell Junius says:

    so is your solar panels still contributing to your power as well? or can only one at a time be charging the batteries?

  24. cyclesingsleep says:

    Would it be possible to put a sharp edge on the front of the fin to cut weeds without adding too much drag or extra maintenance?

  25. Andy Preston says:

    Hey Stew and Zaya 🙂 So does the downhaul hold the blade in a vertical position? Is there any relief if you say hit a log or something with it ? Something like this might same you same damage if it does hit something hard one day. . This would keep the blade vertical, while still allowing some relief if you hit something hard.

  26. Two Dogs says:

    nice, well said on the install.

  27. Doug says:

    Did You build this cat?

  28. Peter Smith says:

    Hello Stewart and Zaya,

    Great video! Now you have the power, do you think you will install an electric autopilot also? Or are the Wharram wind pilots all you think you will need? I just bought the plans for the Wharram pilots and was wondering what you thought before I launch into building a set.

    Once again, fantastic video.


  29. xdawpax says:

    tie 2 knots with a bite in the down rope and put a quick release between the 2 knots. do not cut the rope. this way you can get the weeds off without having to undo all that. just quick release and reconnect.

  30. laredo jim says:

    Nice video. Was this test done without your solar on. Or was your solar charging also. Thanks

  31. andrea spinoglio says:

    Hi Stew,
    I am sorry if I ask a question you have already answered to……
    could you please let me know what is the number of batteries and technology you are mounting on your Boat?
    I am very interested in this water generator, I hope to be able soon to share my experience with it.
    Nice videos and very well explained.
    Keep going
    Best regards and safe sailing.

  32. edward wiebe says:

    How about electric motors?

  33. Paul Smith says:

    Extra power..
    Think about installing a 12v heat coil in Your hot water tank. Or if You don't have a hot water tank, install one.
    I suppose You could also come up with a way to evaporate sea water for fresh water.

  34. DOBM says:

    Another highly enjoyable post which I guess took a LOT of video filming and much more time editing. Very nicely done indeed and highly informative!

  35. mike womack says:

    Nice   ….   ;~D>>   ….   Rrrrrrrrrrrr

  36. shananagans5 says:

    Very nice. When I was a kid in the early 80's we used to sail. We had a little 27 with an outboard motor & I noticed how that prop spun like mad when we were sailing & the engine was down. I told my father, an electrical engineer, that we should make a little prop driven generator that we could drop into the water. He thought I was nuts. He said we pull the motor up because it creates to much drag & then explained how a generator would do the same. I thought a good balance of power generation & drag could be found but he totally discounted my idea. I was to young & already set on where I wanted my life to go so it's not like I was going to do anything like manufacture these units or try to commercialize it but I thought it would be a good, workable, practical idea. It was one of those "somebody should make this" kind of ideas.
    I am actually very glad to see things like this on the market & I am glad to see they work so well. I thought about it for a long time & I thought it was a good idea but nobody else did. I told the marina owner, other boat owners & they all discounted it so, seeing this work so well gives me a bit of a "I told you so" factor. My "crazy" idea is vindicated !!! lol Great vid. It made my day. 🙂

  37. Snake Plisken says:

    Just saw you going up the Caloosahatchee River, Fort Myers. What a small world.

  38. patriotpioneer says:

    Does it cost any boat speed when it's in the water?

  39. Rodell Williams says:

    Awesome explanation from my brother from Grenada

  40. J P says:

    This type of generation will allow to to generate even at anchor. Amazing how things are progressing. I am just amazed at your boat. Kind of like Water World. You truly cruise the world. Like your commentary keep it up.

  41. Bestiverhad says:

    The voice of the person narrating this video, sounds just like your voice.
    So much so, that I have to wonder if it really is you.
    Hope to have a chance to give it a listen.

  42. Tatono Music says:

    Thanks for using my music! 🙂

  43. Prof. Michael O. Zeee JCD ECS says:

    A hydro-generator stops working, when the boat is not moving. I would go for 1 or even 2 wind generators… they stop working when there's no wind (boat is not moving to drive the hydro-gen., does that make any sense) 😉

  44. Damien Tucker says:

    A simple stick with a V shaped end pushed quickly down the leading edge of the hydrogen will push the weeds off, saves lifting the leg.

  45. cartmanrlsusall says:

    the sound of a wooden hull is so different from a glass boat .I think I like it it sounds like its alive

  46. cartmanrlsusall says:

    you need a induction cooktop for your galley,thats a good use for your surplus power ,hot meals with no risk of fire like a gas stove

  47. Michael says:

    You sold me …not much drag either more efficient than my solar alone …well done

  48. Michael says:

    would a line cutter on the shaft help? Those rope pull drag along gens act like a drogue I am told

  49. bill hanna says:

    good for battery health

  50. David Reams says:

    Great overview of the Watt & Sea hydrogenerator. I've been looking into one and your video is the best "real world" test I've seen. Very well done, thank you.

  51. Paul Ohlstein says:

    +Stewart: You could rig a small electric winch to the hydrogenerator and a vibration sensor tuned to the frequency that the weed fouled hydrogenerator experiences. When the vibration is sensed the hydrogenerator is lifted to shed the weed and then automatically lowered.

  52. Bryon Ensminger says:

    You should rig a small cage around the propeller to jeep the weeds off the prop

  53. Kevin Swanson says:

    did you see the charging system that goes in water or air,have a look at that one

  54. Jared Colahan says:

    What's the benifits using hydro over wind. I would think they would work at the same time unless anchored. Then the wind gen would be more beneficial.

  55. Fanima Dekoi says:

    Free Energy costs a hell of a lot of money, apparently.

  56. Barry Bruckner says:

    Curious as to the cost of these and is it offered in more than 300 watt I didn't see a link did I miss it
    Thanks for great info

  57. Seafariireland says:

    Thank you for a very informative video. I have added that to my list of essentials to keep the beer cool if for nothing else. Have you returned to the boat after your stopover in Grenada to continue the voyage around the world? Fair sailing, Ray.

  58. James Wilson says:

    asking for patrons bad idea mate donations to keep up the vids be better way to approach the project good luck good project we need more eco friendly seafaring

  59. zero says:

    if u enjoy making videos, do them for free!! we r grateful and we can generate income just watching your detailed videos! good luck!!

  60. RV Curious De Warren says:

    That’s a nice upgrade

  61. Norman Smith says:

    It's possible to tune a knock sensor to trip the release and relay to then wind back the unit every time it vibrates with weed.

  62. Norman Smith says:

    Or a more angular design that allows for easy weed slip.

  63. Chris Boyce says:

    Based on what you showed the manufacturer should angle the propellor shaft and have the leg enter the water at an angle which would allow the weed to easily be washed down the leg and away. The weed appears to move the moment you released the down haul and an angle changed .

    no link to the generator website?

  65. Black Hat says:

    [7:49]I was surprised when we saw the underside, that all the wiring runs under the deck suspended above the water. (I'm sure it gets splashed all the time. But thinking about the design, I guess there is not to many places you could run it. Since the boat is 4 separate pieces lashed together. (Hmm, how IS the Pod attached to the cross beams?) But I do wonder if you needed to make repairs or changes, or dissemble the boat, is there some big junction boxes under the deck where all the wires connect? Or are you going to have to disconnect all the wires and yank them out of all the stuffing tubes where they pass through the hulls/deck pod?

    Re: The weeds catching on the hydro generator. Instead going through the hassle of untying the lines, raising and lowering it, then re-lashing the lines when its back in place, what about getting a thin stiff wood stick with an appropriately shaped v-notch in the end to slide down the front edge and push the weed off the bottom of the unit?

    maybe i missed it. how far can it go on electric power without sails? whats the maximum range, considering solar and hydro and battery packs?

  68. daniel kinney says:

    wow. that is pretty awesome. I wonder if you need 2 of those.? ??

  69. daniel kinney says:

    love this video.

    Great Electrician!

  71. fred ned gold says:

    on the existing unit that you showed on the other cat ,were they corrosion blisters forming were the generator joined the leg?

  72. Vikrant Shirsathe says:

    This is what we need, how much would it cost if we standardise it? like you have did modification to already manufactured,
    if want to push 3 hull 50 ft. yacht with 5 cabins

  73. Karl Friedrich says:

    Would it not benefit you to tie or epoxy a long knife edge onto the leading edge of the shaft?

  74. jim nickles says:

    I LIKE that Hydro-Gen! Well Wired and thought-out. I would get a Spare Seal to carry Aboard, just to keep That S.O.B. Murphy out of my hair. (Murphy's Law?) And lots of spare Fuses, in case of lightning striking nearby in the water.

  75. climbing and moutaineering says:

    Is its 300W enough?

  76. Marco Vysokaj says:

    well I'm no expert but from what I've seen in this video it seem to me that the problem with seaweed could be easily solved if the the shaft of the hydro gen was mounted and gliding through water in an angle . lets say that now it is in 90 degree angle so if it was at 60 or 45 the seaweed would just slide of without any problem and it would certainly put less stress on the shaft itself .of course I didn't mean to just set it in this angles the whole hydrogen would have to be reengineered but that is easy I'm sure you get what I meant

  77. John B says:

    I don’t know if this has been asked but how much was that system to add on to your boat? I take it you already had the batteries from your solar setup. Thanks in advance mate..

  78. David E C Frost says:

    I am liking the Wharrams more and more☺

  79. Thompson BMX says:

    I am currently working on harnessing the power of farts for generating power. Waste not, want not.

  80. Zeki says:

    Any info on why copper coat is more environmentally friendly?

  81. BlackSheep Expedition says:

    Wish i knew how to sail to try something different then land travel. Great videos.

  82. Paul Beebe says:

    Excellent tech video.

  83. Jeff A. says:

    Great videoography

  84. Jms Fabrication says:

    Does Lucky Fish have a water maker?

  85. 2Wheels R2Wheels says:

    What can you do when you have more power than you can use? Work on your plans for "world domination".

  86. Ted Carruthers says:

    Excess power could possibly be used for power for a small manufacturing unit to produce Viagra…..on the go.

  87. Tom Ocean says:

    install a washing machine, a drier. a dish washer.. A larger freezer …no enough power, what about induction stoves..

  88. Alex Tourigny says:

    Hey Guys, the new Hydro Geni looks like it works great. No moving parts to wear out, no impact on the environment, and gives you plenty of power day or night. Maybe now you can let Zaya talk you into a washing machine. How does the price compare to a solar panel set up ? Just curious to the pay back cost and duration. Nice viedo, and thanks for sharing it with us. Glad to sub your channel Mate ! Cheers & Happy Sailing Guys !

  89. John von Horn says:

    Really enjoyed this one, Stewart. You are clearly a safe pair of hands

  90. Tim Schroeder says:

    How much did it cost for the hydro generator

  91. Jarome Jacksan says:

    You can find best solutions on Avasva website.

  92. FF Film Crew says:

    The off grid freedom is what interests me the most. Being able to lessen the weight by having a smaller fuel tank of petro and having as large of a battery bank as possible and enough wind and solar for at anchor is the sytem that I would want to design. Having your generator be one back up and then your alternator ne the redundant system is a very liberating idea. I would think that the primary necessity is enough power to run the fridges and freezers at anchor. Being able to build a system that can run ac at anchor in perpetuity would be the ultimate goal.
