Lagoon 450S Catamaran For Sale By Owner Location: Cole Bay, Sint Maarten Asking: $599,000 (USD)
S/V Mystic is a US-flagged, 2018 Lagoon 450S Owner Edition catamaran, for sale by owner. The original owners are accomplished offshore sailors with 22 years of experience who have been cruising S/V Mystic through the Virgin Islands, New England, Florida, and the Bahamas since she was built. Mystic is currently in St. Maarten and ready for more adventures. Owners’ children are grown and busy, and business responsibilities make it difficult for them to spend as much time on the boat as they would like. This is their second lagoon catamaran, the first being a Lagoon 410, and they continue to love the brand. Mystic has been the perfect platform for us to make lasting memories with friends and family and we believe it is the best 45’ cruising catamaran ever made. We have traveled many thousands of miles in safety and comfort. Our only regret is that we didn’t order a Code Zero and Spinnaker when we bought the boat for more sail combinations in both protected and offshore conditions. The boat needs only the new owners’ personal gear and provisions and she is offshore-ready.
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)
