The interiors once again reflect the use of composite materials as having both an aesthetic and structural use and the pairing of these materials, with “exposed” treatment, serves to create a modern, light and airy interior. Compared to the “Koala”, “Sheliak” is roomier, since the layout includes two rather than three cabins. The technology used and the design choices made have all focused on safety, fun and comfort. One example can be seen in the centreboard step, which is located in the dinette, fore, where it is a furnishing item as well as a functional piece. Moreover, modern technology has allowed us to create a “transparent” centreboard step so that once the centreboard has been lowered; its visual impact is dramatically reduced. This craft has been built using unidirectional Kevlar and glass fibres impregnated with epoxy resin under vacuum and post-cured at 70° C on a variable density Airex core for hull, deck and fittings.
