Because the old benches of the lifeboat were removed to make more space in the cabin a lot of transverse strength of the hull got lost. This is the reason why the deck broke out and the hull deformed when she sunk.

To add more strength to the hull 3 extra frames were laminated and glued into the hull with epoxy resin. Each frame exist of two pieces together forming the shape of the hull. Every piece is made of 6 layers of iroko, 7 mm thick, 50 mm wide and a length of 2 meter. A model, representing the inner shape of the frame, was made to laminate the pieces together.

Markings for the middle.

Metal strip to prevent breaking.

After 12 hours of drying the epoxy is strong enough to remove the frame from the model. Now the frame is ready to be sanded to remove any excess of epoxy. At last the frame is cut to it's final length.

Now the frame is ready to be fitted in place. A hydraulic jack is used to compress the frame in between the keel and the gunwale of the original lifeboat. Under the frame copper pipes are fitted for water drainage and electrical cabling.

Now that the frame fits perfect in position it is ready to be glued to the hull with epoxy. The frame is taken out for the last time and epoxy resin is applied. The gaps under the frame are filled with wooden wedges to fit perfect on the hull. After a few days of curing the frame will be ready for sanding.
