Radical new mini

Collin, I think we are talking about different things. In my post #46 I was addressing the rep of scows for poor upwind performance, and wondering if a typical scow was unable to heel sufficiently to reduce hydrodynamic drag. This might be true in light airs, but in heavy conditions where the buoyant bow would make a difference there would be no difficulty getting enough lift from the sail to heel it. Insufficient wind on the beam would only apply on a reach, so my question was poorly phrased.

Nonetheless, the sail of a boat close to the wind produces the maximum lift and minimum drag. Just like an aircraft wing, a sail’s lift is produced normal to its surface. Unfortunately, when close hauled most of the lift goes into heeling the boat not driving it along.

 

Here's another take on a rule length boat http://www.shf.org.au/SmlBt/Skiffs/YendPop.html from 80 or so years ago, still in nice condition but too precious as an example to sail. A replica has been built & sails regular now http://www.youtube.com/watch?v=fGwtTyRy0pw

 

And powerful grinding machine to grind off some skin thickness to make it lighter .

By the way, traditional Dutch boats look absolutely terrible shape in plan view -almost square ends -but sail quite well, when heeled.
And do not go forward readily with powerful engines -because engine push them with no heel .

 

One was aluminium and I had no alum. welding capability at the time-- so prefabed the keel at a local machine shop with a fastening flange. Fastened it with something like 400 sealed headed 3/16 marine pop rivets bedded in 3m 5200 caulking --not one leak--sold on 3m 5200 after that. The other ya could have grinded off 1/4 inch of the skin and still had lots.
Maybe those old builders knew their hull technology better than we thought-- cods head and all -- but just didn't have the little extra info to pull it all together. ---All in all Very interesting --Maybe i'll change the orientation of my keel by 180 deg. and present the blunter end as the bow
