A new Sea Pro watermaker has been installed, but has not been operated. Fresh water lines replaced last year. New holding tanks, hoses, and pumps for both heads. Electronics include Raymarine chart plotter, hydraulic autopilot, digital radar, Standard Horizon VHF with AIS, new Icom 802 SSB radio with auto tuner, and Pactor 3 modem. 420 Watts of solar to charge AGM batteries replaced in 2019. (4 house, 1 for start, and 1 for windless. Below she is roomy, with lots of light, and fresh air from the 4 hatches, and 22 opening ports. A large stateroom aft, with a vanity, four drawers, a large hanging locker, head, seperate shower stall, and storage areas. The forward stateroom has a double Pullman berth, 4 drawers, and large hanging locker, with an ensuite head, and storage. The boat is also equipped with an 8 kw gen-set, 2 A/C heating/cooling units, a combo washer/dryer, a 12 cubic foot fridge, and an 8 cubic foot freezer. The salon table has 2 folding leaves, and can comfortably seat 6 adults. 2 barrel chairs, and a settee with huge storage areas below, and behind, and a buit-in bar.

Equipment: LED lighting throughout the boat. 100 gallon fiberglass water tank. 2-90 gallon aluminum diesel tanks (presently full). An oil change pump system for gen-set and main engine. A 10 foot Achilles rib dinghy with a Honda 9.9 hp. outboard. A barrel shade to cover the cockpit, (by Shade Tree). 2 large storage boxes on the aft deck for hoses, elect. cables, dinghy pump, fishing gear etc. Lots of necessary spares included. In-water survey October 2020.

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.
