Duracell Project: Making the doghouse out of sandwich material


The transformation of the Duracell Open 60 is progressing and it's time to start manufacturing the new doghouse. This is an opportunity for an educational step-by-step on how to make a sandwich panel and install it on the boat.

Cutting of the roof side panels

After having taken the measurements and made the templates of the new roof which will be installed on his yacht, Matt is now working on the final superstructure. Constructed of foam and fiberglass sandwiches impregnated with epoxy resin, it will give the former race boat the comfort of a modern saloon deck.

The work begins by cutting the foam panels that will form the core of the material. Matt takes care to leave a few extra centimeters of material on the layout. This will allow the piece to be adjusted at the end of the assembly.

The panels are then laminated to the contact with two fiberglass fabrics on each side. The cutting of the portholes is done once the polymerization is finished.

A well prepared workstation

The secret of a neat and successful job is the organization of the workstation. Matt shows the one he set up for the occasion. From the heater to keep the epoxy at the right temperature to the cardboard protection of the work surface or the bucket of acetone for the tools, he shares with us his good habits.

He then details the preparation of the fabric strips that will be used to ensure the junction with the boat, by impregnating them with epoxy resin

Assembly of the doghouse

The side walls of the roof are finally installed on the boat. The deck has been sanded beforehand on the junction area, to allow the adhesion of the new fabrics. After some slight cutting to fit the boat's shape, a fillet joint is made with epoxy resin filled on the whole base of the panel. Then two strips of fiberglass, one narrower covered by a second wider, are put in place and debulked. The new walls are in place.
