Title: trying to make my boat float
Post by: Coyotes-R-Us on June 05, 2019, 09:31:06 PM
[size=150]Ok it sounds dumb, but.
I'm adding foam flotation to the waterbug. 7'x14' 950 pounds catrermeran style airboat
2- 30"x31"x26" one in each cat along side the motor in back.
26"x 5''x 13 feet. down the middle between the cats,and the two aluminum pods added in back .There roughly 6"x20"x15". That's 72,100 Cubic inches.
41.72 cubic feet. That would displace 41.72 cf or water which is 2603 pounds.
I want to see if that will hold it up.
If I backed it in on the trailer and sunk the boat then un hooked the tie downs but keep the trailer under it with a bow rope and maybe
on the sides too to keep it from rolling.
Then what? If it floats or sinks to the trailer, do you think the trailer would hold the weight when I take it out? There is no extra weight on the trailer in the water , right?
I'd keep the motor mostly out of the water then pump it out.
To crazy ?

I have always been told to have a flotation device on while on the water.  I guess it should work for you boat as well.

If it's gonna float the trailer will come up off the bottom.

Floating with no water in the boat is the easy part.
The foam does nothing but add weight and takes up space till the boat fills with water.

Exactly.. the foam only helps if you sink.  Think the old aluminum canoes with the flotation blocks in the ends. All they were for was to keep the canoe neutrally buoyant in case of a flip over.

It should work the same for you. If ya hit something and sink it should keep you at the surface and off the bottom

How would you check it, test ?
Manufactured boats have predetermined amounts and standards .
I made mine from flat sheets of aluminum with out any directions.
