This 1980 Endeavour 43 Ketch, is located in Fort Myers, FL. The designer of the great boat is Designer: Robert “Bob” Johnson.
Most recently launched September 2020 at which time she received a new hull paint job and mechanical inspection.
Auxiliary power for the Endeavour is the Perkins 4-154 62 HP diesel engine, the Hurst direct-drive transmission (2013) and the Super Glide throttle and transmission cables installed.
Heating and cooling is delivered by the Aft 16K BTU MarineAir reverse Heat/Cool with LED remote panel.
The burners and bowls for the electric stove with oven were replaced June 2021, the microwave oven was installed in June 2021, and the six-gallon hot water heater was installed January 2021.
Holding Tanks: Forward 20 Gallons; Aft 20 Gallons.
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 √LWLA 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)
The Endeavour 43 comes from the first generation of sailboats from Endeavour Yachts, a yard that built its early reputation around simple, straight forward shoal draft designs with big volume accommodation and mediocre sailing performance. True to that formula, the Endeavour 43 was penned by Robert Johnson as a heavy displacement center-cockpit cruiser with large comfortable living quarters and a shoal draft optimized for Florida sailing. The boat was first introduced in 1978, offered in both ketch and cutter rig options, and had a production run that lasted to 1984.
Owners tend to rave about their comfortable well styled accommodations with healthy 6′ 7″ of headroom. The boat can accommodate at least 6 between its forward and aft staterooms and settee berths in the generously sized saloon. The aft stateroom is a particular favorite. Saying the boat has ample stowage is probably an understatement.
With a 33,000 pound displacement, comfortable motion is a given and the ride is very dry. Unfortunately the rest of her on-the-water capabilities do not match her dockside competencies. Windward performance is poor due to a shoal draft keel, she has enough weather helm to make self-steering a problem, and off the wind in following seas her large stern tends to get pushed around a bit.
