This1971 Formosa Ketch 41 is a very sturdy sailboat. The current owner has lived aboard for 25 years. She a perfect bluewater boat and Catalina weekend cruiser.
This ketch was sailed to explore the local islands on a regular basis. The owner reports she’s very stable in 20-30 knots of wind.
An Izusu 60 HP diesel engine was installed to replace the 40 HP Perkins with black steel tanks. It’s very economical when the engine is used. A new 55-gallon plastic fuel tank was added as well as a new 35-gallon holding tank and 3 stainless steel 50-gallon water tanks.
This 41 has lots of space and the amenities necessary for cruising by a couple or small family. With ample room to sleep 6 comfortably, spend the night aboard your Famosa when you sail out to the islands or to your favorite spot.
This ketch is a great project boat. Everything works but she needs some TLC and paint.
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)
Also known as the YANKEE CLIPPER 41. ATLANTIC CLIPPER. Similar to CT-41, SEA WOLF 40, SEA TIGER 41.
