East Asia Composites has been commissioned by the Hebe Haven Yacht Club of Hong Kong to construct a 13 m motor launch.
The naval architect for the vessel is One2Three Designs of Sydney with the Australian office of CCG, an independent Diab Group company, completing the full structural design of the fibreglass and foam sandwich construction. The interior was designed by East Asia Composites.
The primary use of the vessel is for race management in the waters off Hong Kong, with a large open upper deck providing ample space for observing race starts and finishes. The aft wheel house deck has been engineered by CCG to ensure that the crew has the best possible view. The thick sandwich panel ensures that the deck has sufficient stiffness and reduces the need for an intrusive supporting structure for the main deck below. The aft deck structure has been strengthened to allow the vessel to act as a towing vessel for the club’s fleet of smaller day boats and sail training activities.
The structural design of the vessel conducted by the CCG engineers in Australia includes hull, deck and deckhouse laminates, as well as the supporting structure. Multiple engineering design methods were used, including classification rule programmes for the main structural elements combined with finite element analysis of the sun awning to reduce the weight and complexity of the structure.
The hull laminate is constructed with a combination of Divinycell HM and H series foam core material with vinyl ester infused E-glass fibre composite skins. The internal supporting structure of bulkheads and beams are sandwich panels and foam top hat beam fabricated with Diab's Divinycell H foam.
