Default Tunnel Vs. No Tunnel on a Semi V Flat Boat

Any opinions on flat boats with a semi V and a Tunnel Hull?
How much performance can you expect to lose from a tunnel hull?
Any other drawbacks?

POUNDING. Even a slight V in a hull will provide a softer ride than a tunnel OR flat hull.

But the flat/tunnel hull will probably be faster and more fuel efficient. But keep in mind you will need flat water to realize this benefit.

I run a tunnel, but I wish I had the vee... IMHO, the added benefits of a tunnel don't exceed the ride of a vee. Mine still rides nice, but it does pound a little..

I thought that you could get a "semi" v with a tunnel on a flat boat, is that not correct?

Well, I guess based on what you're asking, that's kind of what I have.. Here's a couple of pics.. It starts as a deep vee and rapidly flattens as transform to a mild deadrise at the transom with the tunnel..

The question is all about how shallow, ride, speed and obviously money..





Here I am anchored in about 18 inches (note my buddy standing less than knee high)

I have this boat and really love it. It is a custom hull that you design the inside. front deck no deck, your choice.

I formerly owned a tunnel-hull skiff. The tunnel was a little more significant than what's pictured above. It seemed to trap air (like a cat hull), and honestly landed quite soft after ramping off of large waves.

The only downside that I experienced was occasional prop blowout. This was likely a result of the "disturbed" water that fed through the tunnel to the prop. Obviously, the motor is positioned higher to maximize the shallow water benefit of the deisgn. I probably should have experimented more with different props...

Default Re: Tunnel Vs. No Tunnel on a Semi V Flat Boat

If it were my dicision to make here is the thought process I would follow.

Scenario 1--Outter Banks/Gulf Coast
I fish feeder creeks and tidal flats for redfish, trout, tarpon, permit, etc. Boat will be equipped with polling platform as well as bow mount trolling motor. My typical fishing grounds cover hundreds of square miles of open large bays and marsh/creek system. I will routinely make runs of many miles across open water bays to get to the spot that I want to fish. It is also common for me to go around the "outside" leaving one inlet and running down the beach to enter another inlet to gain access to water that I couldn't have reached traveling by creek or river. These conditions obviously put me in a position to navigate waters that are constantly changing and have the capability of producing a nasty, close chop that we all know is a PITA. For this I would want a flats boat that had as much dead rise as possible at the transom so that in the event of deteriorating conditions I would have a boat that would allow me to travel on plane with the least amount of ball busting, teeth rattling pounding that a tight chop will give you.

Scenario 2--SE NC tidal creek system
Targeting the same type of species as above, but omit from the equation the need to travel across open water. For the inshore fishing that I do in my area, I could concievably avoid open water for the rest of my life. Because of this I would want the flattest bottom on the market. Polar, Carolina Skiff, Southern Skimmer, etc. These types of boats are hugely popular around here and for good reason. Some of the 21 and 24 foot models provide enough room for a mud wrestling ring in the front , ping-pong table in the back , and still leave plenty of room for you to sit in a lazy boy recliner and cast for flounder and reds from the bow.

All kidding aside, if you can avoid open water, get a flat bottom boat.
Limited travel in open water, get something with a tunnel.
Extensive travel in open water, go with the V. As much V as possible.

As you can see from the above references to both the El Pescador and Explorer boats, there are MANY boats made in Texas for the TX flats that will go shallow; have a tunnel; and yet have a high bow for cutting the waves. What they probably won't do ( I've never poled) is be a very good poling machine. The very same high bow that cuts the waves and makes for a soft ride, would, I'd imagine, be a negative for gentle poling. When I read another post along this line, it seemed that a LOT of guys really were not poling that much. They were using their trolling motors or wading. If you'd like a list of a number of similar boats and their manufacturers, let me know
regards, RichG TX

oh yes...p.s. Carolina Skiff now has a V bow in the 13/15/17 foot sizes ( JV17) as of 2006. RG
