Depends on the total boat design, not just one aspect. Also, depends on the size of boat you want. Also, depends on what is an acceptable cruising speed for you. A boat with a keel will only cruise in the low 20knot range at best. Also, depends on your preferred type of fishing. Most deep vees will rock and roll when drifting. So if you are a shark fishing fanatic, I would say a deep vee is not a good choice. I like to do overnights to the canyons, and I think a lobster style flatbottomed keelboat in the 35 foot range is ideal, while still be sort of economical. I think it also makes a great all purpose boat.
