SHANNON CONSTRUCTION TECHNOLOGY

Although every Shannon appeals to traditionalists from the waterline up, the timeless classic look is complimented by a yacht designed and built with the latest technology and material. As an example, Shannon has been using isophthalic gel coat since 1978, long before the "blistering" problems of production boats became public. Shannon pioneered composite core linear foam and biaxial laminate construction in 1981 to increase strength while reducing weight. Shannon removed all balsa wood coring on decks in 1984 and replaced balsa with closed-cell cross linked PVC foam to prevent delamination and rot from potential water migration. In 1986, Shannon began to use vinylester resin and epoxy undercoating for additional hull protection. And, since 2002, Shannon hulls have been reinforced with Kevlar and carbon hybrid laminates in areas subject to excessive impact in grounding situations. The US patent issued in 2004 for the SRD (Schulz Reverse Deadrise) hull design has been acclaimed as a revolutionary breakthrough in fuel efficiency and fast motor yacht performance. Windows on all Shannon wheelhouses since 2009 are armor plate heat tempered glass with ceramic coated edges permanently installed to the deck with Space Age adhesives rather than aluminum framed safety glass windows that can flex and fail in big seas. Every proven innovation in electric systems from AGM batteries to galvanic isolators to “smart” chargers and inverters are incorporated into all new Shannons. While many builders especially those in the Far East are still building boats with 1980’s technology, Shannon strives to incorporate the latest and greatest in equipment and systems -- always with the proviso that everything that goes into a Shannon has been proven to stand the harsh test of the open ocean.
