I made the seat backs from 8mm corcell M80under vacuum with 200gm plain weave glass each side.
The edge has a strip of the panel doubled up and a layer of 300gm uni carbon to each side to strengthen.
There is a recess made into the edge that will house LED strip lighting.
There will be a coloured night setting to not affect night vision as well as a white light for when at anchour.
So the main lighting in the cabin will be indirect.
It will also have a light above the dining/chart table for use when reading charts.
The seat backs were not taken down to the seats but join the hull further up.
This was done by applying a 100mm wide layer of glass, 50mm on the edge.
This was wet out with fast hardener and once cured but still green, put in place and the other half wet out against the hull.
When cured any gap was filled and glassed over.
