ALPHA IS FOR SALE
This iconic C Class Catamaran was commissioned by Fred Eaton, designed by Steve Killing (with input from Fred and Crew Magnus Clarke) and built by Multimatic Technical Centre in Canada.
Sailed by Fred and Magnus, she won the Championship in 2007.
Sailed by Glenn Ashby and Jimmy Spithill, she initially led the 2010 event, eventually finishing second to Fred and Magnus sailing Fred’s new C Class, Canaan.
She was then used by Team Groupama to assist in the development of their all-conquering foiling C Class.
Team Sentient Blue then acquired her at short notice to compete in the 2013 Falmouth ICCCC. Silver medallist Luke Patience and Paul Larsen (Sail Rocket and Team Invictus) shared helming duties, crewed by Sito Aviles…we learned a lot!
Her last regatta was the Geneva ‘Little Cup’ (new name for the ICCCC), where she won one race in light air, helmed by A Class Nordic Champion Thomas Paasch and crewed by Filip Walczak.
She has been stored in her custom 10m trailer (included in price) since then and is in excellent condition.
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)
C CLASS CATAMARAN rule began with the creation of the International Catamaran Challenge Cup, first sponsored, in 1960, by the Sea Cliff Yacht Club, located in Long Island, NY USA. The event, loosely called the Little Americas Cup, continues to this day, although only intermittantly in recent years. Among development classes, it is recognized as one with the fewest restrictions. Boats that are built to the C Class rule are among the most advanced and fastest sailboats in the world for closed course racing.
Restrictions are as follows:
A crew of 2.
Maximum LOA is 25’.
Maximum Beam is 14’.
Maximum Sail Area is 300 sq feet. (For the past 20+ years, the sails have been multi element solid wings with varying methods of control)
There is no restriction on weight or design of foils.
