- Welcome to the 2024 boat propeller breakdown!
In this episode, we dive into the worlds largest boat show and ask every propeller exhibitor to explain their unique features and benefits.
Yes, we’re even touching on 2024’s hot topic, Regeneration!
Whether you’re a seasoned sailor or just starting out, understanding the right propeller for your vessel is crucial for optimal performance on the water.
Join us as we break down the differences between propeller types, including fixed, folding, and feathering designs.
Explore theadvantages that have arisen to become the modern propeller
Don’t miss out on this essential knowledge that will help you make informed decisions for your sailing adventures!

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
A fantastic comment! That’s great to hear and really valuable info. Thanks! 👍
Great and informative video about the different props, really helpful! Big Hugs
Cheers Nuno! Great to hear from you!
Catch up soon lad👍
Nice work, this is good made and interesting topic!
Cheers Rolf, much appreciated 👍
Just found your channel thru Sailing Uma, I thought.
Then I realized I had been watching several of your videos but never subscribed. You do make some awesome content. Keep up the good work!
Nice!! Cheers matey! Glad to have you on board 👍
Nice job! I appreciate you asking about power generation and looking forward to what is next big propulsion moves in the work of sailing.
Thanks! We’re right into the regen so do stay tuned 👍
I hope your channel grows, great topic and well prepared and thorough interviews. Look forward to more videos coming. Thank you 🙂
Cheers! Super nice of you to say👍
Great presentation 😊
Cheers princess! 😜👍
Great information! Thank you for your effort
Cheers👍
Amazing video 🔥🔥🔥🔥
Cheers matey 🤙
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.
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?
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.
@@Beamerboy_ sounds fab, I would love to talk further, we have quite a project that we are starting soon, I think it will interest you - www.sail-hub.com
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..
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!
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.
Definitely, it’s something that people should think about a bit more! What was the outboard?
Discussing Sharrow propellors would have been appreciated.....☹
For sure the toroidal designs are quite interesting but we can’t talk to them if they are not there!
As per Sharrow, when I spoke with them, they're highly optimized for outboard motor applications.
Shame they aren’t so good at folding although we can’t have it all!
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.
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 🙂
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 🤙
@@SailHub My Brother-in-law had a 30 something yacht in Cowes, I had my American Power Boat in Cornwall, he hated me waving at the power boats , (truth be told I love both). All very posh in Cowes. Now surface drives - now we are talking. Lousy in reverse - bit like a sail boat really 🙂
@@Roskellan 😂👍
1st lol
As in first view? What a legend 👍
Ahhh, Jenni’s says you mean lol as in laughter. Mate, I’m so hip!
