Our Amel is 32 years old, has a MaxProp and we have a shaft alternator that produces around 7amps at 24v sailing 6 to 7 knots. We simply put the engine into reverse while sailing forward to get the blades of the prop to lock out. Then we go to neutral and turn off the engine

@@SailHub our boat is at Beaumaris on Anglesey. We are now committed to moving aboard and launching in 12 months time. Our two 48v battery banks (4 x 300AH and 4 x 120AH) are installed in a watertight compartment. Motor in a frame ready to fit. Thrust bulkhead built. Currently mostly focused on deck. DIY carbon fibre stanchions and solar rails. Then mizzen mast (diy dyneema chainplates and rigging). Visitors welcome 😁

Love your work - we have a Bruntons Autoprop = I have just redone the bearings as we get ready to cross some ponds..my understanding is diesel is still the cheapest per kilo watt hour - correct me if I am wrong... please can you do a series on Watt and Sea hydrogenerators - they seem controversial in that some love them - and some sailors say they are a waste of money - would love your insights..

@SailHub 5 ай бұрын

Thank you! So, yeah I think your probably right on kw/hr prices. Things will change as sales ride though. There are some aweseome new products out now though which are insanely good at generating huge power! Like the Integrel 9kw alternator, that can also be adapted to run off a shaft drive!

@Beamerboy_ 5 ай бұрын

We at Torqeedo have really god results with the Gori propellers. We use them on the normal non overdrive position. You can take more power out of them bevor they fold back compared to other props.

@SailHub 5 ай бұрын

Cool, thanks for letting us know! That’s really worth knowing for our next project, I would love to see the numbers too! What is it you do at torqeedo?

@Beamerboy_ 5 ай бұрын

Application Engineer in the High Voltage / Deep Blue Range. It is hard to get numbers of hydrogeneration, because every boat is different and every prop behaves different. Most important factors are boat speed and diameter. Fast catamaran (14knots) with 17“ Gori folding props will generate 5,6kW. Slow longkeel ketch with 28“ prop will do 1,5kW at 7-8 knots. Soon we will have data from a variable pitch shaftdrive setup, I am looking forward to that.

Interesting topic for sure, I'm a bit surprised we're not a bit further forward in the developiment of hydro power for sail yachts, we get the forward motion for free after all! It might not be a factor you want to get involved in but price comparison would be interesting. Good video though, thanks!

@SailHub 3 күн бұрын

@philipwright7186 hey Philip, good to hear from you. Yeah, hydro generating is somehow still a bit of new thing for many companies! We hope to do a ton of testing based around that subject on the boat build we’re on with. As for prices, we’re going to start putting them in the description as they change all of the time making the videos inaccurate.

Encountered any electric dingy outboard that have decent regen capabilities? Not having high hopes, but I can easily mount one on the back of my sailboat with the prop facing forward to turn the outboard into an electric hydro generator and recharge the outboard battery when under sail. You can't use your outboard when sailing anyway. Annoys me a bit, would love to have a dual-purpose outboard. I could build my own outboard or hack an off the shelf one, but already have so many other projects... Might also not be possible if outboard motors require a high sailing speed to be able to regen power compared to the low speed motors used in hydro generation. Being able to swap props depending on mode would also be useful.

@SailHub 5 ай бұрын

Definitely, it’s something that people should think about a bit more! What was the outboard?

I think Mr Brunton said that the prop needs to spin backwards for hydro generation. I don't think that's correct. The direction of rotation shouldn't change.

@SailHub 5 ай бұрын

I would imagine he was meaning the prop needs to be span backwards to invert the blades, from there the water will spin it in the same direction but with the blades reversed. He’s certainly a switched on guy, we spoke for ages!

@@SailHub to be fair i do have a Brunton Sigma "CV" type coupling on my gearbox/shaft drive on my yacht and it is very well engineered and has been very reliable. So i do think the company, generally speaking, has integrity and credibility.

Propellers - never mind sailing you are moving into power territory here 🙂. I was talking to a boat designer for power boats, particularly twin motor power boats and therefore over a certain power counter rotating props. LH and RH rotation. I ask him if you put them on the opposite sides (for forward propulsion obviously) would it make any difference? He said they potentially could steal water from each other leading to cavitation if put on the wrong sides. Funny enough he said during testing they tried just that, looking for differences in performance. He said on their particular boat it made no difference to performance what-so-ever, but they left them on the wrong sides anyway because - and get this, the wake looked prettier 🙂 Sorry but I couldn't let a sailing channel get away scot-free talking about propellers 🙂

@SailHub 5 ай бұрын

Cool! And your right. I believe counter rotating props can cause cavitation if not far enough away from each other but their main reason is to counteract prop walk 👍 As for us mind, boats are boats! You’ve gotta love em’ all 🤙
