what is the difference between a triton with a tunnel hull vs "normal" hull?

Tunnel hulls are hulls with a tunnel literally in the middle of the hull. Instead of coming to a "v", there is a little tunnel. It forces water to the motor so you can run with the motor at a higher elevation. It's used to take off and run in shallow water.

i should have worded the question better. i'm aware of what a tunnel hull is designed to do. however, i see a few cc boat with a traditional-looking "Vee" front that are advertised as tunnel hull.
pros and cons of running in a chop with a tunnel hull?

The tunnel on those isn't in the front, you'd have to look at the back/underneath.

I think it depends on the hull on how it handles in a chop. I do know that you lose speed and efficiency with a tunnel. If you need a tunnel hull, you probably wouldn't be considering a traditional hull. If you're on the fence, I would go traditional hull.

Most production boats that are labeled tunnel hull are really semi tunnel. They only have a tunnel channel for a foot or so before the prop. Not thru the entire length of the hull. Look at that closely if it matters to you.

My theory is if you need a tunnel on your bay boat, then u really just need 2 boats..... one to fish bays, and the other inland.

As mentioned above, speed and efficiency go down with a tunnel.

I like the Podna or family system.
-have a Friend with each type of boat and your set.

I know in my family, i have a flats boat, brother has bay boat, and father has offshore boat. it works out great.

The tunnel hull will allow you to jack the motor up higher than the static water line and not ventilate. Only works if you have a jack plate installed on the boat as once you are on plane it will allow water to reach the prop at the higher settings and not blow out.

What they are referring to should actually be a 1/2 tunnel or pocket tunnel. A true tunnel runs the length of the hull and is wider in the bow and narrower in the stern to "tunnel" water to the prop, allows for crazy shallow running.

Pocket tunnels offer some shallow water benefit in slightly less draft and ability to plane off in slightly less water. You lose some top end speed and some ride quality in rough water. A good carolina flare (on the bow) and trim tabs help a lot on rough water and mask the tunnel ride quality. It's all a give and take.

that's what i've always seen. you can have 2 out of the following 3 things in a boat: good ride, speed, and fuel efficiency. one of the 3 will always be inferior to the other 2, take your pick.
