I'll try to.

It's 14 feet long, with a strong v-shape to the hulls. At the bow the hull is 18 inches deep, finishing in a point, and curved. At the widest point the hull is 17 inches wide. The hull is curved asymetrically - a sharp curve at the bow becoming more gradual as it goes back. The stern is 11 inches wide by 12 inches deep, again in a v-shape. The crossbars are connected directly to the hulls, although the front crossbar is slightly higher in the middle than the rear crossbar, due to being angled at about 20 degrees. The tramp is attached directly to the hulls.
I took it out once as a trial run, and it was surprisingly fast. I felt it was underpowered with the paper tiger rigging, but it left paper tigers for dead, and could hold its own (more-or-less) with an Alpha-Omega that was following an identical tack. I'm not sure if this is due to the aluminium or the shape of the hulls. It certaily wasn't due to the rigging or my sailing ability.
Actually, I was mostly attracted to the lines - it has, I feel, an elegant shape that looks fast, although I suspect it will be best in heavier winds.
Originally it appeared to be set up to take a jib, and my guess is it is about 20 years old, but that's just guessing. The last owner had it for 10 years, and it had two coats of paint under what he had applied. I have since tracked down two others, but haven't been able to contact the owners.
Thanks for any help with this - I would like to get it back to the original state, as I like the idea of an aluminium cat.

It is, if nothing else, solidly built.
