OK, I don't know if anyone here will be able to help me with this question, but I thought I would toss it out there just to get some input.

I am looking to purchase a new boat...... for diving of course. I am going to use it for other boating activities as well. Anyway this is what I am looking for, and anyone with any insight just jump in.

I want something as small as I can find that will allow at least 4 passangers, be useful as a dive boat, be trailerable, and able to go at least 10 miles offshore (NJ area mostly). Basically what is the smallest size boat I can go offshore in? I understand the size will limit the conditions I can go out in, so something for the nicer calmer days. Which boat is most useful as a dive boat for recreational wreck diving? Feel free to add anything that I am missing.
