Seller's Description
This is my second Martin 243. It is more refined than the first one. It has a lot more work and evolution to it. Most people sell their boats when the sails are worn out. This is not the case with this Martin. In fact, a new jib has not even left the bag. I just acquired a Flying Tiger 10. Have not sailed it yet. I will not keep 2 boats. We just took the Martin 243 boat out two days ago and reaffirmed how much fun it is. Every single piece of the Martin is new. Shrouds, blocks, running rigging, new Kiwi Grip, you name iy: it is new. The bottom is terrific as are the blades. Trailer has a spare tire. There is a boat cover that covers the entire boat, past the waterline. Every system in the boat has been reworked. It is a boat you can step into and race.
- Single axle galvanized road worthy trailer, good brakes, repacked bearings, with spare tire
- Boat is still sailing, would still be racing if there were races
- Carbon mast, aluminum boom
- New square top main, 2 jib(s) one still unused,
- Two new kites (reacher and A/P)
- Extra set of practice sails, main in excellent/race worthy condition. 2 jibs (fair)
- 3 extra kites – practice worthy
- 6 month old shrouds
- All new running rigging – all are technical lines
- 2:1 white sails halyards
- Covers on shrouds, bones to make sure they stay fixed
- Gator on forestay
- New speedo
- Mast cover (for jib) on bottom of mast
- New rope bags (4)
- Ratchet blocks
- 4 HP two stroke Mercury outboard with external tank
- Multi point beam hoist
- Gin pole

Calculations
- Hull Speed

12.2 kn
Classic: 6.57 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
- Sail Area/Displacement

56.2
>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.
- Ballast/Displacement
-
29.6
<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
- Displacement/Length
-
46.8
<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
- Comfort Ratio
-
5.6
<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
- Capsize Screening
-
2.9
>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
Notes
Beam incl. wings 15’.
Sail Area:
Main: 318 sq ft.
Jib: 135 sq ft.
Spinnaker: 555 sq ft
Crew: 3-4 persons, Max crew wt: 700 lbs
