TRUTH NO. 4: NEVER GO TO SEA IN A BOAT THAT CAN SINK
Great Harbour Trawlers are unsinkable. We know what you are thinking. Unsinkable? That's what they said that about the Titanic. For the record, the Titanic was only unsinkable as long as her watertight bulkheads remained un-compromised by sharp objects such as icebergs.
Bouyancy is a key to seaworthiness. The reason Great Harbour Trawlers are unsinkable is twofold: 1) Unlike some trawlers, our boats are unballasted, and 2) Our decks and superstructure are cored with a wonderful, high-tech, composite material called Nida Core. Nida Core is lighter and stronger than the plywood used in many boats. Even better, it is so buoyant that it will compensate for the weight of a solid fiberglass hull and machinery, thus keeping the vessel afloat even if it is swamped with water.

Nida Core is a honeycomb of hexagonal cells bought in sheets. And though it is more expensive than other coring materials, it is also lighter. That reduction in weight allows Great Harbour to pass on fuel savings because less horsepower is needed to push the boat.
An added advantage is Nida Core's terrific sound-deadening qualities. The Yanmar engines we use are quiet to begin with. Put them under Nida Core and we guarantee dramatically reduced decibel levels in the pilothouse and accommodations. Not only is Nida Core proof against noise, but it is an effective insulator in both hot and cold weather with an R factor of 3.3 , or up to 5.5 with the foam-filled version.
