I've had the best results from Google
. In the search field put in "Craigslist and boats". You won't get one list with all the boats but the results will list the city first. You can replace "boats" with the specific type of boat you're looking for ie. "Craigslist and Searay". Sometimes you have to go 5 or more pages into the search results to find what you're looking for.

"It's not the boat "you built" until you've sworn at it, bled on it, sweated over it, cried beside it and then threatened to haul the POS outside and burn it!"
