Isophthalic acid (IPA) resins in the outer layers used during the laminating process ensure that the hull of a BAVARIA is of the highest quality. These offer effective protection against osmosis and thus promote longevity of the BAVARIA. The hull and deck of a BAVARIA is formed by sandwich construction with foam inserts. In sailing yachts the deck is reinforced with aluminium sheets where fittings are mounted. In the so‐called „marrying“ process shortly before the end of production, the deck and hull are screwed and glued together.
