Default Re: Bracket tub shape opinions

I could run the 21 degree deadrise portion farther up before the transition to 13 degrees. I avoid trying to slope the tubs bottom upwards as it goes back just because that seems harder to lay out in a way to build a mold.
I like that idea. It might provide a little more flotation. You can make a more dramatic reverse chine in it also if you want. I think the seamark has a bit of a reverse chine in it. Lets keep in mind that the shape of the flotation chamber is as imortant for boyancy as is the size. My bracket down side up.



I snapped a couple pics of the motor today to see exactly were my anticavitation plate sits. It is actually about 1.5-2 inches below the keel of the bracket.

The point here is, that anything above the waterline just add's weight and has no effect on flotation to help the boat sit level. Only what is submerged does have a effect.
Looking back I probably could have made the sides of my flotation chamber deeper thus providing more flotation. Also I probably could have mounted the bracket 1.5 inches lower.

Here are more pics:



Make sure you leave enough room for your transducer if it is going to be a transom mounted.



make sure that you can stand on it and have dry feet....



Why in this photo does it appear that the bracket could be mounted a little lower....



while in this photo it looks like the bracket is mounted just right....




Theres a lot for you to consider. It hurts my head to think about it.
