Lagoon 440 Catamaran For Sale By Owner Location: Palmas Del Mar, Puerto Rico Asking: $345,000 (USD)
S/V Nani is a highly sought-after and wonderfully maintained 3-cabin Owners Version, 2007 Lagoon 440 catamaran for sale by owners and has never been in charter. She has an enclosed flybridge that made sailing the Eastern Caribbean comfortable with spectacular views of the great open ocean. In addition, she features upgraded low-hour Volvo Penta 58 HP engines, a generous sail inventory, a full 48,000 BTU A/C throughout, and 800 amp-Lithium batteries with 1000 Watt solar, Spectra water maker, Washer, 7000 watt Onan Generator, that leave you totally self-sufficient. These are just a sampling of the upgrades she holds. Nani is bluewater capable and excellent for liveaboard.
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)
Replaced with the LAGOON 450.(2010?)
