43 Sailing catamaran for sale by owner. Pro Kennex 420 / 445 It was launch from the boatyard as a Pro Kennex 420 model. But it is basically a Pro Kennex 445 with shorter transoms. Same molds used, same hulls, interior, layout, width, installations, sail plan, everything. Please do not compare with wooden catamarans (plywood core or balsa core, like Lagoon, Fountain Pajot, etc) Price is USD 260.000.- / 223.000.-
6 cabins. 4 double berth with private head and shower 2 single berth cabins with door access from fore doble berth cabins and hatch access from deck. Located currently in Mexico (Isla Mujeres) on a private mooring (included in price, if sold while the boat is in Isla Mujeres). Most likely sailing plan is (in order to arrange for visiting): Panama (San Blas) from December 2021 to March 2022. USA (Florida) on April 2022. Altantic crossing to Portugal in May 2022. Ibiza from June to September 2022. Portugal (Algarve) from October to November 2022. Atlantic crossing, from Portugal to Caribbean, December 2022. Ready to sail anywhere in the world right now. The biggest catamaran cockpit of his range. The widest (24.7’ / 7.5 mts) catamaran of his range (this width if usually found in 50 foot or larger catamarans). Catamaran safety and stability is given by its width!!! There is no wood, plywood, balsa anywhere in the superstructure (deck, walls, bulkheads, reinforcements) of this boat. Wood and plywood was used in the interior furniture only. It is all built in polyester resin over Airex (closed cells PVC foam), using vacuum bag and infusion technics. Hulls below waterline are solid fiberglass. Very light, reliable and durable. All the bulkheads (8 per hull) are built in fiberglass over Airex sheets and glassed to the hull. Not sika-glued like most mass production catamarans. Designed by the world renowned Van Peteghem and Lauriot Prevost (VPLP). Was built in France in 1992. Complete refit in 2020

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)
