Southern Cross is ready to go! It’s an Out Island 41 cruiser live aboard on steroids! As she sits she is move on ready. Also sail ready. All new standing rigging and Harken genoa furler with solid sails will get you sailing immediately. She has not been sitting. She is currently in use!
Equipment: New standing rigging, main and miz, 2023 New main mast running rigging New Harken genoa furler 2023 New custom s.s. main mast step New Highfield aluminum “v” bottom dinghy with new Tohatsu 9.9 4 stroke motor New - 2x 4D house batteries, 3 way battery controller, alternator, battery charger Hauled out August 2024, new bottom paint, blister free bottom! replaced 3 thru hull valves, refastened rudder plate, prop and shaft in good order. Rudder good shape. Foam in all interior cushions replaced, cooling memory foam. In good working order: late model bow thruster, windlass, large claw anchor, 225’chain, spare danforth anchor, air conditioning/heat, refrigeration, micro wave oven,3 burner stove,(oven needs repair), water pressure works but needs service. hot water heater, 2 heads, one electroscan, other holding tank, Engine Perkins 85 hp, runs well, starts everytime, Diesel generator Northern Lights, Sails - Main solid with stack pack lazy jack cover, genoa solid approx 130%. Mizzen used, light duty. Nav/Electronics - Garmin nav system, VHF, binnacle compass, Raymarine depth sounder (new transducer), Simrad Auto Helm with wireless remote (really nice) Full Cockpit enclosure
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64)2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Sloop or ketch. A somewhat rare OUT ISLAND model.
Probably from the same mold as the MORGAN OUT ISLAND 50/51.
(Unfortunately no picture at this time.)
