Ok guys, my wife is really wanting to get a boat. By boat I mean an RV on the water. We live up in the Puget Sound. I have two boys one 10 one 15. Now besides a main cabin and bunks or a queen bed in the other. Twin engines, what should I really be looking for in the boat. We are looking to spend the weekends and in the San Juans and around the Sound. Advice would be more than welcome.
