2018 JFA Yachts Long Island

Listed
Expired
$9,500,000 USD

Seller's Description

NDSE is hull #2 in the Long Island 85 series. In the constant search for weight reduction JFA Yachts paid particular attention to the use of light materials, including laminates on honeycomb cores for the construction of the interior, the hull out of aluminum, a superstructure made of composite, and the Mast and Boom are made of Carbon Fiber. This resulted in a lightship weight of only 56T for this 85’ performance, cruising catamaran. Delivered in 2018, NDSE was designed for circumnavigation through both poles, and has already been taken to Antarctica by her current owner. Whether you are cruising in the tropics or the arctic the NDSE is built to make sure you are comfortable and safe in all conditions.

Equipped with a carbon mast and boom, NDSE features a sail plan tailored for high-performance sailing together with hydraulic fittings on the flybridge which ensures she is easily handled, even with a reduced crew. Externally, the yacht offers a large aft cockpit with a relaxing seating area on starboard and a dining table on the port side, together with large sunbathing areas and a daytime toilet. In order to limit the overall weight of the boat, the use of teak was limited to the deck forward of the owner’s cabin, the aft cockpit, and the flybridge.

In terms of performance under sail, she is very quick…. The sails were made by the highly respected sailmaker “Incidences” using the latest D4 membrane technology in order to combine form with stability, lightness, and longevity. NDSE achieves 11 knots upwind and 12 knots under gennaker at 90 °, with 15 knots of true wind meaning that she is capable of very good daily averages when cruising.

French interior design house, Darnet Design, created a sophisticated yet understatedly elegant interior using natural tones. The furniture is in oak, contrasted by the addition of walnut with the space enhanced by the addition of multiple soft furnishings in bright colors to lift the entire space to another level and also allowing for an element of customisation by the new owner. The cockpit flows into the huge main saloon, with a bar on starboard and a more formal dining area on port side. Forward is the chart table which includes all the navigation equipment, significantly upgraded for global exploration by the owner, together with entertainment and excellent communication systems which allow for long stays on board.

The owner’s cabin occupies the entire beam of the boat, including a lounge area and large windows which flood the room with light and allow for splendid panoramic views as well as private access to the foredeck.

The port hull accommodates the owner’s bathroom, a children’s cabin with 3 beds, together with a guest cabin aft. The aft section of the starboard hull accommodates the 4th guest cabin. The forward section is dedicated to the crew with the captain’s cabin, a double cabin, and large galley with crew mess.

A 16’ tender aft of the cockpit is launched using a Tenderlift platform.

The many exterior lockers offer ample storage for fenders and mooring lines as well as an array of leisure equipment (inflatable longboards, Wakeboard, etc.). NDSE also has a large trunk overlooking the rear platform to store 4 bicycles as well as diving equipment.

Calculations

Hull Speed
5.6 kn
Classic: 6.21 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

5.56 knots
Classic formula: 6.21 knots
Sail Area/Displacement
13.4
<16: under powered

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.
13.39
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

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

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
494.9
>350: ultraheavy

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
494.89
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
32.1
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
32.07
<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
1.8
<2: better suited for ocean passages
>2: better suited for coastal cruising

Imported to the US by Harling and Ringstad, Staten Island, NY, in the early 1960’s.
