1991 Custom Bluewater Cruiser by Elephant Boatyard UK Fly Ian Howlett Aerorig

Listed
Expired
$90,000 USD

Seller's Description

A self-sufficient blue water expedition yacht, REV FLY is ideally suited for cruising remote regions of the world. Built to an exceptionally high standard with a focus on reliability and redundancy of systems from the start, this attention to detail has been maintained throughout her life. All major systems are fully backed up with secondary independent systems.

Launched in 1991, FLY has proved to be ideally suited for short-handed offshore cruising in extreme comfort. She has completed several transatlantic crossings, two single-handed. The unique rig design and powerful propulsion and thruster system facilitate exceptionally easy maneuvering in close quarters.

The offer is for a co-ownership interest in this small superyacht. Why charter when the cost of co-ownership is considerably lower? Each of the co-owners will have four weeks per year under their direction and options for additional weeks on passages and expeditions. Cruising grounds will change each season. Our plans for the next five years include expeditions to the islands in UK, Norwegian Fjords, Iceland, Greenland. Summers in the Mediterranean and winters in the Caribbean.

Ownership rights will be conveyed as shares in a for-profit corporation. Co-ownership shares will consist of rights to use of Fly for 4 weeks each year. Two weeks will be offered in the prime season, and two in the shoulder seasons. Scheduling of weeks will be managed by a corporate administrator with a rotating order of priority using a shared online schedule in order to ensure fairness for all owners. Each of the co-owners will have a specified number of shares in the corporation that is holding the Fly, and owners will have voting rights in the management of the corporation at regularly scheduled online meetings.

This offer represents significant advantages over chartering a boat similar to Fly. The cost to charter a 70’ sailboat $15-20K per week and is restricted to coastal cruising. Co-ownership in Fly will pay for itself in less than two years and will provide opportunities for rea expeditions.

Equipment: The design and build of Fly is of the highest quality. The original cost was over 2.1M. Replacement cost is nearly triple that. The raised areas in the ceiling give light below from multiple directions, giving Fly a very open and airy feeling throughout.

Calculations

Hull Speed
?

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

?
Classic formula: ?
Sail Area/Displacement
?

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: 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
?

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
?
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
?

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
?
<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
?

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
?
<2: better suited for ocean passages
>2: better suited for coastal cruising
