Sheffield Insulations ( there is a branch near you, check Yellow Pages ) The standard blue foam used in the construction and building trade is the stuff you want. It absorbs less than 1% moisture. Easy to work, cuts with saw, hot wire and sands well. Won`t resist polyester unless with a barrier but OK with epoxy. Comes in various thicknesses in 8x4ft sheets (or metric equivalent). Oh yes, try to get some Corrosion-X for dipping your radio and electronic gear, from USA.

You basically want closed cell foam. Most DIY stores will have some variant. Such as the pink "Foamular", or the blue foam. I believe these types are called extruded polystyrene foams.

Open cell foam will gradually get waterlogged. I would avoid the white bead foam that can also be found in hardware stores.

Last summer I did some fpv-boating, just for fun. I made an airboat/swampboat because I had the parts for it. I'll share my experience..

The waves are difficult to compensate, the boat tilts in all directions, including up and down. Place the camera's in the center to minimize that. Wind and currents make the boat drift, causing rotation. When sailing the motor makes noise, could be a problem for wildlife approach. (airboat sounds like airplane, bad choice)
The low point of view causes the water to mirror/reflect. Think about backlight compensation when choosing the spot to shoot from, the sun also reflects on the water and hull (paint it black!). All this considered, the idea of a barge as platform seems logical.

Pointing the camera would need a video signal transmitted to the operator...

Quick compulation of the footage from the airboat, forgot to mute sound...
Hope it's helpfull...
