I am looking at a few boats right now in the 10-15k range, but I have my heart set on either of these 2:
Cape Dory 25D
While not the the boats in these ads, they are in very similar condition, so I do plan on putting more money into whichever I choose...
1978 contessa contessa 26 sailboat for sale in Alabama
1984 CAPE DORY 25D sailboat for sale in Rhode Island
Good Luck with the search, Take Care!
