That's interesting to know! Either of those explanations sound plausible. The myth is probably so common because it sounds very believable, the...
Just been directed to this article. It's a good description of a kitchen rudder on a 40 foot harbour launch. Not sure if the boat's still for...
Come to think of it, is owning a boat ever worth it? They cost lots of money and you could get wherever you're going quicker by air or road ;)
Very good question! It's hard really to say if it's worth the effort, I'd say yes but partly because I enjoy the challenge of designing and...
Just got round to uploading a clip of it in action. q-p5ic2jAB8http://www.youtube.com/watch?v=q-p5ic2jAB8
Anyone know anything about props, is this a good idea or should I stick with 18" diameter?
I'm also planning on changing the prop while it's out the water. I currently have an 18x12", but the engine struggles to get much over 1500 rpm...
I'm sure it would 'work', although I doubt it would be optimal. As said above the general wisdom seems to be that the shells have a lot of...
Removing the lips should indeed increase forward thrust, but would it also make the rudder try to pull closed? I'm thinking of changing the lips...
More musings Surenw, yes I can email you my drawings, they're not great though as I was in a hurry making them and they were only for my own...
Thanks for your kind replies. So far so good (touch wood). Still not done so many miles, but clocked up quite a few hours charging batteries. The...
There is no thrust loading from the prop. That's transmitted directly into the hull by the python drive. I take it that's what you meant?
Well, it's on the water, and alls good. Not used it for that long yet, just moved her about 20 miles from where we craned her in to her mooring....
Well, the boat's on the water and I think the rudder can be counted as a success. Haven't got any particularly good photos of it in action yet, or...
It's made for my boat. I 'designed' (plucked from thin air might be a better description) the shape of the clamshells and machined the tubes and...
