What Ranger42c said about your personalization choices.
Also, think about any limits you may have, tall, short, knees, balance, technical ability, etc.
At this stage I looked mostly by search terms without boat type except power boat, length, price, and diesel fuel, to bring in as many boats as possible. Some people use odd terms to describe their boats.
I used other sites as well as Yachtworld, which generally has the nicer, more expensive boats. I used Boat trader, boats.com, and even Craigslist in boating areas across the South and East coasts. I also found looking at detailed drawings or user websites like the Defever or Grand Banks clubs helped me find details like headroom, layout, and user reviews.
Good luck in your search. JohnS
