So while we are waiting for Bob Perry to get back into town and he has a few minutes to look at this, and while I had a an hour to kill before yoga last night, I thought I would take a first stab at the 'A sleeper in Wolf's clothing' version. This would be the version where Wolf walked into a yacht design office and said, "I lost my boat in a hurricane and the insurance company is paying me to build a brand new boat from scratch. I really loved my old boat but would love to improve it a little...emphaisis on a little, without losing a thing I liked about my old boat." In other words, this is the "Mommy Jeans" version. It is also the version which requires the least time and skill to draw.
I figured we could employ comparatively modern wood building techniques, say epoxy saturated, glued, western red cedar, bead edge strip planking, with a couple diagonal WRC veneers and a perhaps a kevlar sheathing over a mahogany outer veneer for toughness. That should bring hull weight down a little, and improve strength and impact resistance a lot.
I don't have a lot of time this morning but here is how this stacks up....
Things which would not change perceptably:
-Visual appearance above the waterline
-Ability to run aground without damage (long keel root and foot)
-Same engine position and approximately the same center of buoyancy
Things which change a very small amount:
-Motion comfort (the boat should roll through a smaller angle at a slower speed therefore be more comfortable than this already seakindly boat)
-A little less displacement over all (maybe 500 lbs to a 1,000 lbs)
Things which should change noticably:
-More stability (center of the lead ballast is roughly 10-12 inches lower)
-Should be able to carry a considerably more sail area (good for light air) and have to reef later(good for heavier air)
-Less drag due to less wetted surface, smaller tip vortex, and less displacement (better fuel economy and better upwind and downwind speed through the water.)
-More efficient foils (better light air and upwind ability, lighter helm loads, less leeway)
-Better control backing and the ability to make tighter turns.
That is my first stab at this. I am sure Bob will be able to critique and improve this version a lot.
