I sail my Ariel with a friend who has a Bristol 27 - another Alberg design. We both complain about the stern squat in these boats. I am about to add weight into the upper bilge from the middle of the forepeak step to the forward end of the forward access hole in the sole. I'll test the results before I glass in about 100# of lead (tire weights, sand, and epoxy slurry).
My theory is that getting the nose down even a bit will not only reduce the irritating slosh in the outboard well, but help the boat be a tiny bit more close winded.
I may be completely wrong. I'll keep you posted on the results.
