How viable would a large kite (on a string - no mast) be as a back-up propulsion method? You can't rely on being able to salvage mast parts or...
The boat shop (garage) should make it all worthwhile, and a boat under construction isn't such a bad replacement view. You're now well placed to...
The boat worked well enough to justify building a full-size prototype, but it takes money to build one, and how do you raise the funds for that if...
A lot less than that - I reckon the prop would be just about level with the aftmost point of the hull.
Look at the picture though (the pink hull one) - imagine the curve of the drive shaft the other way up and it would join to the propeller with the...
Why not miss out the belt? Just put the flexible drive shaft inside a curved foil that ends up horizontally linking direct to the prop.
Folding inwards or out? I'd look at opening it out into a flat sheet to fill the gap between the beams to minimise drag when not in use. How...
But he is listening, and he's making progress towards something practical and non-lethal - it's a massive improvement. It's even heading in the...
That looks viable, so long as the transom doesn't go too deep - I don't know the rules for that, but I'd have thought it shouldn't go further down...
You might get a better idea of the route by reading a book called "the unlikely voyage of jack de crow" - a mad Australian rowed/sailed most of it...
I still don't understand your outriggers. Why do you need them for stability in calm waters if the keel/ballast will keep the boat upright and...
I don't know. For a rough idea, look for something similar and read the statistics on the design. For a more accurate idea, you'll need to crunch...
If you were building a dinghy, the beam of the boat would put a limitation on how far the crew can sit out to balance the boat, but if you have a...
What use are the tiny outriggers? If they're going to have hydrofoils on them, that might make sense, though only if the boat can go fast enough...
I'd recommend that you have a much higher displacement of the boat in the middle third rather than having nearly equal amounts at the bow and...
