First question would be what do you want to use said sloop for?
I live aboard a 28.5 ft. LOA Pearson Triton, it is much smaller than your averaging cruising boat, but maintenance costs, procurement cost and dockage are much less than a larger boat. My solution may not work for you though, so a basic idea of what your needs are would help find an appropriate solution, for example,
1. What will you be using said sloop for?
2. How much sailing experience do you have?
3. Roughly, how much is your project budget?
4. Do you want a turn key boat, a project boat, or something in between?
5. Is this a day sailor, a weekender, or for extended cruising/living aboard?
6. Any construction preferences (fiberglass, steel, wood)?
7. What dockage solution do you have (driveway, on the hard, in water)?
My baby...
BOAT = Break Out Another Thousand, unless, of course it's over 40 ft. LOA then it's Ten-thousand...
