Seller's Description

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.

Calculations

Hull Speed
8.0 kn
Classic: 7.93 kn

Hull Speed

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.

Formula

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

7.95 knots
Classic formula: 7.93 knots
Sail Area/Displacement
16.0
16-20: good performance

Sail Area / Displacement Ratio

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.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
16.02
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
36.4
<40: less stiff, less powerful

Ballast / Displacement Ratio

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.

Formula

Ballast / Displacement * 100

36.36
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
343.4
275-350: heavy

Displacement / Length Ratio

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.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
343.42
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
39.5
30-40: moderate bluewater cruising boat

Comfort Ratio

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.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
39.52
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.8
<2.0: better suited for ocean passages

Capsize Screening Formula

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.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
1.75
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

From BlueWaterBoats.org:

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.
