Welcome! Do y'all have any boating experience? The best advice I can give is to start chartering different styles of boats, get out on the water NOW, learn if the boating life is for you, and what you want in terms of ergonomics, creature comforts etc. Then you'll be able to narrow the field down dramatically while having fun doing it.
