Seatback Buoyancy | Installation

The next job was to fill the interior of each seatback with foam to provide buoyancy.

As in the bow compartment, the preferred material is PIR (Polyisocyanurate) insulation board, obtained from a builders' supplier.

I had purchased two full sheets of 25mm board for the seatbacks, thinking it would be more than enough. In practice I used all of both sheets.

As in the bow compartment I used a finely serrated kitchen knife to cut and trim the pieces of foam.

Here is the starboard seatback, stuffed with foam.

This is the view from above.

I find it reassuring to know that there is an entire 2.4 x 1.2m sheet of buoyancy in each side of the boat!
