All Kraken’s comprise of a one piece hull and integral Zero Keel which houses a sealed lead ballast bulb.

The hull lay up is built using 17-22 layers of composite engineered fabrics bonded together by vinyl-ester resins.

The general hull thickness is a minimum of 15mm.

Aramid fibre composites (Kevlar) is also used in all impact areas, the bow stem, the front of the keel and the keel base.

The hull topsides incorporate 25mm closed cell foam, the FRP foam sandwich which extends from 40cm (16″) above the waterline to deck level. This structure improves insulation and overall hull form rigidity.

A Kraken’s hull and structures exhibited no flexing.
