You say you want a blue water capable boat. Are you planning on crossing oceans or are you planning on island hopping around the Carribbean?
I ask because I'm not sure I would trust a $50k boat to cross oceans with, but there are any number of $50k coastal cruisers that would be fine for island hopping when you are rarely more than 100 miles from land.
Funny to think that worry would set in at the 99 mile mark. I'm most scared from the slip to the last channel marker.
