Note - the original plan to use WEST (i.e. saturate hull with epoxy) didn’t materialise because the result would have been too heavy. The lining is rubber paint and the Kevlar skin is not fully bonded to the hull. This saves about 2kg at the cost of some strength, but the result seems quite strong.
