The liner extends from the forepeak area to just aft of the engine
compartment and extends vertically about 2-1/2 feet above the bilge
. The liner is installed in the hull with epoxy
resin while the hull remains in the mold
and is still "green" to provide a chemical as well as adhesive
bond. The liner strengthens and stiffens the hull, particularly in the area of the keel
step and provides torsional rigidity that the hull alone, or reinforced with bulkheads alone, cannot provide. As a by-product, the structural liner also ensures the exact alignment of bulkheads and the furniture that provides stiffness and support for the deck
. In areas where one normally needs access to the hull, e.g. the bilge
sump, the liner is cut away before it is installed in the hull and the edges adhered to the hull with layers of woven roving. Those that decry the building methodology and generally ill informed and lack an engineering background to understand and appreciate the function of the structure. I'm sure the self appointed experts will disagree quite vigorously however.
