2019 Corsair F-24 MK I trimaran

Listed
Expired
$27,500 USD

Seller's Description

A famous sailboat designer once said “People sail for fun, and no one has ever convinced me that sailing slow is more fun than sailing fast”. Corsairs are sailboats for people who enjoy sailing fast. F-24s have an amazing record in the R2AK (Race To Alaska) and this F-24 has a current PHRF Rating through Bay Area Multihull Association of 93.

I recently took a friend out for his first sail on a Corsair. Reaching across San Pablo Bay he looked at me and said “I’ve never been on a sailboat doing 14 knots”. I said “Hang on, it gets better”. And it did.

They are versatile, well-balanced, safe and fun to sail. Corsairs fold up for easy trailering to extend your sailing horizons. “Stingray” has been on San Francisco Bay, San Pablo Bay, Lake Tahoe, Folsom Lake, Bellingham Bay and the San Juan Islands in Washington.

Well-equipped for short-handed or single-handed sailing. In very good shape “for her age” (she has always exercised regularly). Set up for overnight camping with butane stove, sink, porta-potty, inside berths, or pup tents on the trampolines

Comes with main, two jibs, screecher, assymetric spinnaker, 2019 9.8hp Tohatsu electric start, tiller clutch, tiller pilot, chartplotter/fishfinder, VHF, jacklines, USB ports, solar panels, solid trailer.

Calculations

Hull Speed
11.2 kn
Classic: 6.51 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

11.16 knots
Classic formula: 6.51 knots
Sail Area/Displacement
39.5
>20: high 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.
39.48
<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
61.2
<100: Ultralight

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
61.18
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
2.5
<20: lightweight racing 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
2.49
<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
5.9
>2.0: better suited for coastal cruising

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
5.89
<2: better suited for ocean passages
>2: better suited for coastal cruising

Mainsail area: 22.5m2/243 sq.ft.
Blade jib: 11.3m2/122 sq.ft.
Assym: 53m2/570 sq.ft.
