Double XX Boats

[JamiePatterson]

The math of skeg, prop diameter, and water intake height isn’t an exact science. The tunnel sends it shooting up like a fire hose. I realize that you know infinitely more about an outboard motor wrench. I just have gobs of experience running these things on the Arkansas River chasing ducks. Misspent youth and all that jazz 😂

Try that with gravel instead of sand or silt.  I dare ya.       😅

No gravel in the Laguna. Mostly hard sand bottom.

👍 well there you go 😀 Since I don’t guide, the layout of fishermen hadn’t been something I thought about. I run the trolling motor and fish from the front deck with the guys with me standing wherever. I’m not worried about them at all 😂 I guess it would stink to be a paying customer standing in the middle of the boat. Makes perfect sense

Well your scenario is probably great for spin fishing but when you have 2 clients that want to sling double hook streamer flies you need some separation and you want to be the lowest profile in the middle of the boat or you are going to be digging a few hooks out of your head.

That makes perfect sense NB👍

That's a sexy looking drifter, but I'd forgo a tunnel Hull design.  

By raising a section of the hull you are just forcing the lower portion of the hull deeper.   You can prove that to yourself by making "hulls" out of 15" pieces of aluminum foil, putting a handful of penny's in them and floating them in your kitchen sink.   Regardless of the position of the outboard in relation to the hull.....you're still running the motor at the same depth (from cav-plate to skeg) ya know?      

It's a bit confusing, but think it through.   

In other words....Show me a shoal that you can run in a tunnel Hull....that CAN'T be run in a flat bottom Jon.  

ehhh, wrong there. a tunnel hull will definitely run shallower than a flat bottom, but it may not drift as shallow.

Regardless of what hull you're pushing....This is the absolute minimum amount of water you need for a prop outboard to safely clear an object at WOT....

2 cylinder motor 

 

6 cylinder motor....

Here is picture of a typical South Texas skinny water setup. The jack plate not only lifts the motor higher but sets it back about 8 inches from the transom. The prop sucks water up thru the tunnel and the compression plate keeps the water on the prop. Once on plane you can jack the motor higher where the bottom of the skeg is actually higher than the hull and still run. These boats are rigged with low water pickup nose cone to keep the water flowing.

Here is a video of one running over a 4 inch sandbar, which is common down there to get to some of the better fishing areas.

I almost forgot this old video that my neighbor, Matthew took running his boat in water that was less than a foot and some less that 6 inches... This is where we fished.

😂 Yeah you can hear it chewing sand!   Try that over gravel and rocks, I dare ya.

Guys on the Mississippi did that alot too.....until somebody invented these.....

Once again.... There ain't no gravel or rocks down there.

Whole point of this discussion is "necessity is the mother of invention". 

The South Texas guys have modified shallow running outboards over the last 60 years and have come up with some great innovations to get you where you want to go.

I think Double xx has a good idea also.
