Lagoon 420 Catamaran For Sale By Broker Location: Saint Augustine, FL, US Asking: $315,000 (USD)
S/V SUNBEAR is a Florida based 2008 Lagoon 420 catamaran for sale by broker.SUNBEAR is a nice example of the spacious Lagoon 420 with a 4 cabin layout. It has always been privately owned with no known charter usage. The design of the Lagoon 420 focuses on comfort. The light oak Alpi woodwork and the laminated wenge floor give a modern and relaxing feel. Access into the saloon from the cockpit through a sliding glass door on the same level. The longitudinal galley opens directly on the cockpit, it is the most convivial and practical area, fully equipped with numerous lockers. The layout of the two hulls in the 4 cabin version are symmetrical with a central double bed in each cabin, a washroom with separate shower, large hull windows, lockers, and overhead hatches.…
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)
When first introduced the LAGOON 420 was advertised as ‘the first series-produced sailboat with diesel-electric drives as standard equipment’.
A number of layouts available with owner or charter versions.
Offered for sale/charter from the Moorings company.
An updated version is the LAGOON 421, equipped with the more conventional twin diesel power.
Replaced with a new (2015) LAGOON 42. (listed here as LAGOON 42-2).
