I have a 10-7 which is of the same design. If I were to move to a smaller boat, I would not hesitate to go with the 8.7. The advice about survey is good advice, however, if you don't want to spring for the survey, I would advise a moisture meter, and look for moisture in the deck. Especially around chain plates, or any fittings that go through the deck. Also, the ports are a source of water intrusion into the surrounding bulkhead and deck.
