2021 Best Most Durable Wind Turbine Canoe Stern Cutter?

Hello mates-
Researching the most durable wind turbine to buy/install on Pacific Seacraft 40 with an existing Monitor Wind Vane, yes this is a challenge.

Any info on latest tech info for a durable solution I have a thick radar pole on stern that might be adaptable.

IDEAL new install wind turbine produces 600watts of energy.

Re: 2021 Best Most Durable Wind Turbine Canoe Stern Cutter?

I would suggest a vertical axis turbine mounted abeam the mast maybe with sail deflectors. Not as efficient as a HAWT but doesn’t need to be mounted at stern, less of a safety hazard and almost no likelihood of entangling sheets or leech lines.

Re: 2021 Best Most Durable Wind Turbine Canoe Stern Cutter?

Vertical Axis Wind Turbines (Darius & Savonius Rotors) would be a structural [1] & aerodynamic nightmare on a sailboat, and are inherently MUCH less efficient [2] than Horizontal Axis Wind Turbines.
[1] Think [vert.] cantilever.
[2] A VAWT puts out about about 30% of a comparable HAWT.

Re: 2021 Best Most Durable Wind Turbine Canoe Stern Cutter?

I would not have considered VAWT until Uma got one and I thought thru all the tradeoffs.

Yeah, not as efficient per swept area. Who cares, it's still fuel-less energy whenever the wind blows.

Doesn't instantly shred sails or present nearly the safety risk.

Lot quieter: an advantage both as something you have to live with and to not annoy neighbors.

Uma's mounting method is to hoist it towards a spreader using a swivel at the top of a rotor and hold it down using a torsion rope to the generator housing at the bottom.

This puts them away from the prime realestate at the stern where I would want to mount lots of solar.

Not sold on them by any means, but would now consider wind instead of rejecting it almost out of hand.

Re: 2021 Best Most Durable Wind Turbine Canoe Stern Cutter?

HAWT turbines produce little enough power anyway until the wind gets to 20knts at which point they are often quite intimidating to be close to. In general wind turbines are not efficient enough to be considered a major contributor to your power generation. VAWTs are even lower.

Makes more sense to design a mount to hold a solar panel.

I think folks should approach maximum solar before even considering something else because that is the best bang for the buck, is silent and has no moving parts and almost no maintenance.

The utility of wind is that it specifically is not solar. I think wind is the next step after solar and provides power if there is anything more than a zephyr. Nope, not as much power, but given that it can produce 24/7 rain or shine.

The model I gave a link to above claims to put out 96W in 10kt wind. That's 8amps. Let's assume that it really puts out half that, 4amps. 4A for 24hr is 96Ahr. I wouldn't discount that.

Re: 2021 Best Most Durable Wind Turbine Canoe Stern Cutter?

We also have a PSC 40 and a Monitor wind vane. We use a D400 mounted on a Kato Marine pole setup; keeps it way out of the way of the wind vane and does not use space that would otherwise be for a solar panel. No it does not put out the power like a solar panel in full sun, but traveling at night or in a windy anchorage it does very well. We just came down the coast and saw 35 kns in some spots with no effect on the D400 at all. All in all, I am very happy with it and would do it again.

We are in San Diego and leaving for Cabo in 2 weeks. Maybe we'll see you down in Mexico!

NOTE TO MODS: I have now tried 3 times to get the photo uploaded in the proper orientation and cannot do it. Perhaps a mod can assist? And school me at the same time

Re: 2021 Best Most Durable Wind Turbine Canoe Stern Cutter?

Best most durable?
1. superwind 350
2. D400

Anything else you might as well buy a $200 chinese unit that claims 600w, but will never approach that number.

More Solar first, more battery second before even considering wind gen
To get any useful amounts of power from a windgen you need 20-25knts.

I believe this generality is unwarranted. Four years ago, I installed a Silent Wind 400 that I have been pleased with. I don't require 20 knots to generate "useful amounts" of power. It's also quieter than most other units that I have been around.
I do agree that solar is the first consideration in the mix.
