Been there, done that, and I know how you feel. We just bought our first new boat. After a lot of research we decided to go with the Arima - not a popular boat out here on the East Coast - but I have to say we're very very happy with it thus far.
In any event, the boat purchase decision is a very personal one indeed, and you are wise to go into the purchase, as with anything else, as informed and knowledgeable as you can be.
Here are some internet resources, but I also recommend that you go down to marinas and take a look around, talk to people, etc. I, and most others I am sure, would be happy to share information about boats, both the positives and negatives. (No boat is perfect!)
OK - so here's a list of resources -
1.BoatUS Reviews by Owners
You can search their database of boat reviews by owners, based on manufacturer and model. Here's an example of what I learned about Sea Hunt boats from that site:Sea Hunt Owners' Reviews
2. Powerboat Reports
presents frank, honest, thorough, detailed reviews of boats and boat products it tests. Because they do not accept any advertising, they are very similar to the Consumer Reports organization. It's one of my favorite sites. You can search their database of boats they have reviewed, read an excerpt of the review, and purchase the review for a nominal fee. It's definitely worth the money. Their review helped me make up my mind on the Arima, although they reviewed a smaller one (18')than the one I purchased(21').
3. David Pascoe's
site is a must read - there is so much information on that site about boats: boat reviews, buyers guide, maintenance, structural issues, hull design, etc.... It's a site not to be missed if you own a boat or are preparing to buy one.
Well that's all I can think of for right now. If I think of anything else I will post it. In the mean time, take your time, do your homework, and most of all, have fun, and get what you want!!
