53' JFC Marine Lifting Keel Aluminum Expedition Sailing Vessel

COMMISSIONING YET TO BE COMPLETED WITH 38 ENGINE HOURS.
Maximizing security in a custom boat focuses on the risk of collision at sea and capsize in heavy seas. Colliding with a barely awash 250,000-lbs container at 7/8 knots will instantly sink a fiberglass boat but merely crumple the bow of an aluminum boat--which it is engineered to do but without intrusion of water. Dave Gerr, in his Elements of Boat Strength, points out that aluminum, for the same weight, is stronger than steel but being more ductile than steel is therefore better able to absorb energy. Welded construction eliminates leaky decks. Monstrous seas are not required to cause a capsize. In 2014, prior to her sinking in which all 4 crew perished, the 40' fiberglass deep fixed keel Cheeky Rafiki had reported 5 meter seas. A crashing beam sea can cause any fixed keel boat to pivot on her own keel into a capsize. A lifting keeler's ballast is low in the bilge; freeboard is higher and WL beam wider: AVS (angle of vanishing stability) numbers superior to many fixed keelers can be achieved. With the keel retracted the boat safely dissipates the energy of the crashing sea by skidding downhill with the rig's polar moments absorbing the roll energy. The concentration of weights gives lifting keelers unequaled seakindliness and the adjustable draft enables them to seek shelter in mangroves when tropical storms threaten. Swing keels, unlike lifting keels, incorporate the ballast thereby preventing the boat from being sailed safely when retracted. The lifting keeler constructed of aluminum has become the formula of choice for extended cruising. Jimmy Cornell, the cruising guru, has covered more than 200,000 miles in aluminum lifting keelers.
