Re: Deck boat vs bowrider???
I pretty much concur with the previous posters. I wanted a new boat and had to ask myself similar questions before deciding.
I do want to point out some characteristics that a lower number deadrise can offer (we?re talking deck boats primarily). One thing is that the boat is very stable at rest and in motion. Another is that you will usually get on plane faster and maintain plane at lower speeds (good for fuel economy, beginners on water toys and most wake boarders) although trim tabs can be added to a boat to improve some of this performance too. I do agree with most posters that a smaller deadrise can contribute to a harsher ride in more aggressive chop, but I would also point out that it probably has a greater effect on deck boats under 21?. Our family?s first boat was an Evinrude Sweet 16 Tri-hull with a 90HP I/O. I think my teeth are still a bit loose from riding in that boat when the water surface was rougher than glass. My experience on my new boat (which is 23?) has been one of being pleasantly surprised how well it handled some pretty substantial chop from some of the bigger northeast lakes (my Coast Guard Buddy riding with me was also impressed and he was stationed in the North Atlantic) and it has a 12.5 degree deadrise. So I think the extra length and weight helps the ride in this department. I will admit that this is not the right hull design for deeper ocean use. Inland water and calm bays on nice days is where most deck boats perform the best and belong. Where you intend to use your boat will have a profound effect on your decision.
Another couple of things I thought would be good to point out concerns the engine/drive system and a head. Although there are good arguments for both outboard vs.I/O?s, the I/O drive does allow you to have a full width swim platform which can be appreciated when engaged with water toy activity. Also, the family does appreciate having an enclosed head on board (actually, my wife and daughter REALLY appreciate it), so you may want to consider it in your search.
I chose a deck boat because I really liked the versatility of being able to fish, cruise, lounge all day, and/or engage with water sports and do it all well with one boat. It was the right decision for me and my family.
Good luck and welcome to boating!
