2017 Jeanneau 51

Listed
Expired
$449,000 USD

Seller's Description

Koa is a meticulously maintained Jeanneau Yacht 51 that received high praise in a 2023 survey, being described as in “Bristol condition”

Highlights of Koa Include:

Onan 4 Kw diesel generator with 121 hours!! Engine hours 1064 (April 2024) Air Conditioning throughout Standing rigging is described as new condition Running rigging 2022 Sails serviced in 2023 Safety gear for offshore cruising Removable davits Pantry with front loading freezer installed 10ft West Marine Dinghy 2022 9.8 Tohatsu dinghy 2023 Waxed hull and bottom paint April 2024

Her layout includes three cabins and two heads, with the master suite forward featuring a private head, a VIP starboard aft cabin, and a queen-size port cabin. The L-shaped galley and pantry make it ideal for extended cruising.

Its spacious and open cockpit provides excellent visibility from the twin helm positions. The electric folding swim platform/terrace at the stern offers easy access aboard and a relaxing spot for enjoying the sun.

Designed to be easily sailed by a shorthanded crew, the Jeanneau 51 offers upscale accommodations for couples or families, with ample storage space for gear and provisions. As the newest and smallest boat in the company’s Yachts range, the 51 is tailored for owners who plan to spend extended periods aboard, both at anchor and under sail.

In terms of performance, the Jeanneau 51 excels under sail. With only 10 to 12 knots of wind and sails sheeted tight, it can reach speeds of up to 7 knots while heeling onto its chines. Off the wind, her speed remains impressive, with the code zero, she can really fly

Calculations

Hull Speed
11.8 kn
Classic: 9.07 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

11.82 knots
Classic formula: 9.07 knots
Sail Area/Displacement
19.0
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.
19.01
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
29.9
<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

29.86
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
147.8
100-200: light

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
147.83
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
27.0
20-30: coastal cruiser

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
27.0
<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
2.0
<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
1.95
<2: better suited for ocean passages
>2: better suited for coastal cruising
