Superyacht Adastra, 42.5m Power Trimaran
John Shuttleworth Yacht Designs Ltd.

The superstructure is carbon fibre with Nomex honeycomb core, the hull is glass/kevlar foam sandwich and the interior is light weight oak cabinetry using honeycomb panels. To help reduce weight, virtually every aspect of the boat is custom built. This includes carbon fibre hatches, portlights, ladders and even hinges, which are all built specifically for the vessel.
