For the structure of our sailboats, we use high quality plywood: CTBX, full Okumé, with Class-3 gluing. Thickness varies between 12 and 15mm, depending on the RM model.
The hull itself is in marine plywood, with panels of 15, 18 or 22mm depending on the parts and of course the RM model.
The laser-cut panels arrive at our French shipyard, in La Rochelle, ready to be assembled and glued.
The assemblage is done on a template mould, integrating the iron part which will support the keel(s).
It is done « upside-down » for a better holding and an easier access.
Gluing is done with a bi-component epoxy.
Then come the plankings, made of plywood too, (except for the RM1180, our 39-foot bluewater cruiser), which are mechanically held so that they fit with the hull shape.
