I am reasonably familiar with the Galilee. When I first moved to Maryland, an aquaintance was looking to buy one new and so we went down to the factory in Mayo and looked at them being built and later sailed on one that belonged to a friend of my acquaintance. They were OK boats. Neither extremely well built but seeming to be reasonably solid.
In terms of sailing ability, when we first went out there was pretty light conditions and the boat seemed a little short of sail area for her weight. Things picked up as the daysail progressed and in moderate conditions she sailed quite well. I thought she was a handful in a stronger breeze and having trouble completing tacks reliably in a chop. I had concluded that some of the observed performance flaws comes from the Galilee''s extremely beamy hullform. Still these do make a nice daysailor.
