I've been looking at a Dixie Bowrider. I noticed it has a tri hull. I understand the physical (observable) difference in the two hull styles but can someone explain the difference otherwise. How does it affect the driveability of the boat?

not sure on the tri hull but I have twin hull and it is great compared to my old style boats " v bottom's and I had 7 of them "
I guess I'm a believer now they would always say " once you go cat you never go back :) "

The outer sponsons on a tri-hull allow the hull width to be carried further into the bow, typically to accommodate forward seating. They also make the boat very stable, both at rest and underway. The downside is that tri-hulls typically ride very rough, so it really depends on where and how you want to use it. The ride is more akin to a flat-bottom skiff than a V-hull, so they do get bumpy in a chop.

Ok, thanks. I figured there was some sort of tradeoff.

Boat builders gave up (for the most part) on tri-hulls many years ago. That should tell you something.

I began on a Kennedycraft 15' tri-hull. Very stable for in shore fishing.

When I look back on the things I did in that boat----I should not be alive today.

Thank you Lord for carrying my dumbness through my grand Darwin Award attempts.

And yes--that boat beat the crap out of me one day about 8 miles offshore......... along with the six passengers..............with a Johnson 75 Seahorse.........:banghead:

At least it wasn't self bailing.

Trihull is great for calm areas where you want a stable platform at rest (fishing while anchored). You can get a much bigger and more stable front deck (due to the large buoyant area in the bow). The down side, as said above, is the larger area also works against you in rough (or even choppy) water as it can’t cut through the waves as a deep V does, it tends to bounce on top of the waves. Trim tabs help to force the front down and not to bounce as bad, but it isn't a fun ride in 1+ foot seas.

V's, and especially deep V's, that carry a strong V all the way to the transom tend to rock and roll when anchored and tip to one side if you are walking along the edge in a boat under 20 feet or so (depending on how high the boats center of gravity is, etc etc).

I prefer trihull's for rivers and protected bay's, but always use V’s for offshore.......

Depends on your application as to which works for you……

Tri Hull = Future Dr. appointments w/ a back doctor. They will beat your teeth out in any waves 1' or larger. I boat on Lake Erie and a buddy had one that we would perch fish with late in the season. I have never been on a boat that would beat you up so bad. Inland lakes is the only thing a tri hull is good for in my opinion.

My parents bought a 17' MFG back in 1973 and had the boat for 35 years. Extremely roomy and stable and as others have said, will rattle your teeth in a chop and I should know as I ran the crap out of that boat in all kinds of conditions.

In Australia we have had a pretty well reguarded tri hull in the Hydrofield range http://hydrofieldtrihulls.com/. They are used extensively by various marine rescue groups in some of the more dangerious areas. They never really caught on in the rec angling world for a variety of reasons but few have ever had a bad word to say about their safety and ride.

my bass boat is tri hull. Definitely helps when distributing weight to outer edges of the boat. nto sure if that helps...
