aluminum boat floatation - AluminumAlloyBoats

2021-11-25  The first alloy boat that I built - i put thru commercial passenger survey. It had to have flotation foam fitted. The naval architect who designed it used his program to calculate the volume under floor for foam fitting and compared that to the special calculation for buoyancy to work out how much foam was required under the floor.

Flotation Froth - an overview ScienceDirect Topics

15.3 Foam fractionation. Foam fractionation, also called protein skimming, air stripping and froth flotation, removes surface active (surfactants) dissolved organics and suspended solids, which may be produced in the culture system. If aeration is vigorous, the process can also drive ammonia and volatile components directly to the atmosphere.

Best flotation reserve method Boat Design Net

2017-3-31  Basically there are two ways to go. Spray foam (two part mixed pour foam) or block pre-made foam. Each has it's advantages and disadvantages. If this is a one off boat the best and least expensive way to go is block foam in boxes under the seats. You can buy it at any hardware store (blue or pink insulation foam) cut it to size and put it in place.
