The Cape Horn 82' TriDeck
Built with redundancy in mind, the Cape Horn 82' Trideck was
designed to withstand the most grueling passages.
A heavy gauge, double-planked steel hull is utilized to ensure safety in the shallows, but it also increases the displaced weight beneath the waterline, resulting in added ballast and greater sea-keeping stability. To offset the weight of Cape Horn's hull, the superstructure is constructed from aluminum, which helps reduce roll momentum.
Sea keeping stability on this yacht is a by-product of a hard chine with active & passive bilge keel stabilization. A bulb is incorporated to add sub-surface length, which helps reduce pitching and its large expedition bow helps disperse spray in North Sea conditions. This provides excellent heavy weather capability and a seakindly motion that helps keeps a land-lovers lunch... down.
Poseidon redesigned her flared bow and this resulted in an increase in vessel length, which also improves performance. The bilge keels and stabilizers have now been relocated further aft for greater efficiency. The totally re-shaped bulbous bow now offers better heavy weather performance and projections indicate a potential 10% to 12% increase in fuel economy with the added bonus of a 1/2 knot increase in vessel speed in calm waters and a 1 to 1.5 knot increase in speed capability in moderate to heavy seas.
Bottom steel plating from her keel to above the waterline is now 5/16” to assure maximum tolerance against collision or grounding. Her other steel hull and deck plating has been increased in thickness to produce a stronger and more uniform fire resistant hull. And, the rudders have been re-designed for more protection against unchartered reefs.
Sea water transfer trim ballast tanks have been incorporated instead of the more conventional static lead ballast, which can not be removed to lighten ship when negotiating shallow waters or moved to accommodate trim needs at various cruising speeds.
