Thank you Aaron, you are very kind. I would like to say that I had this idea whilst in the bath, and ran into the street yelling eureka! But the...
I think this is an interesting idea. I'm assuming you mean that the foil would have a positive angle of attack relative to the waterline, but a...
I seem to recall reading an article once about someone who had fitted a windmill to a small yacht or catamaran, I can't exactly remember which. I...
Never mind. It was a silly idea.
We seem to have crossed posts. No analogy is perfect. A foil is just a mechanism to extract energy from a moving fluid. As such it is subject to...
Thinking a bit more about this, you could say that friction is accounted for by the piston friction against the cylinder wall and turbulence is...
Not entirely. As an explanation for the phenomena of lift, both the Bernoulli model and the Newtonian model ignore these factors. They are factors...
Well yes, an analogy is a story of sorts. It's used to convey an abstract idea. If you haven't gained any insight into the idea or hypothesis I'm...
I have only skimmed through your paper. I will read it in more detail later.
I was wading through some of the threads started by Sailor Al, but quickly got bored. However, it did get me thinking about how to describe lift...
How much depends on how far aft the rig is. Over the years, Hobie 16's have raked their rigs further aft to increase the loading on the more...
Why do you think canting a wing would be any different to canting a 'normal' sail?
Thanks Tom. At this stage I just require a realistic section to use for thinking about few different arrangements, but if I ever build anything,...
Tom, Slightly off the current topic, are the section co-ordinates for the H105 freely available? I'm looking for a section suitable for a surface...
From the images presented in this thread it would appear that junk rudders are relatively small and I would guess that they operate at high angles...
I think the situation for a ballasted yacht is a lot different that that of a dinghy. The advantage of the scow is its greater stability upwind...
I agree. In my experience, and not with scows necessarily, a fuller bowed boat will tend to decelerate rapidly when the nose goes down, leading to...

It would depend on the type of cruising you wish to do. The requirements for blue water cruisng will be different to those for coastal hopping...
Some of the old scow Moths had hulls that were effectively wider on the waterline near the bow than near the stern. Using that principle, you...
