Design and Construction
The Martin 243 is a fiberglass monohull with solid hull and deck cores and a lifting keel. It has an 8.25-foot beam and draws a maximum of 5.75 feet. Its 29.66 percent ballast-to-displacement ratio and displacement-to-length ratio of 46.83 place it firmly in the ultralight category. The monohull has a lifting keel, allowing it to be dried out or trailered despite its racing draft.
That low weight is central to the design. The 450-square-foot fractional sloop rig drives a boat that weighs less than many trailered dinghies.
Rig, Performance, and Handling
The generous fractional rig gives the Martin 243 a sail-area-to-displacement ratio of 56.32, helping to explain the published verdict that it is a very high performer. It is reasonably stable and stiff—important qualities in a boat this light. However, the same authority notes a poor ability to right herself after a knockdown and a capsize factor of 2.92. Those figures mark it as a lively racer for upright-weather sailing rather than an offshore cruiser.
A comfort ratio of 5.62 and a hull speed of 6.56 knots complete a profile focused on speed in flat water rather than comfortable motion.
Accommodations and Auxiliary Power
Recorded accommodation data for the Martin 243 is almost entirely unknown. Headroom, cabin count, berth count, head count, and water capacity are all listed as unknown. The sources establish that the boat carries one engine, but its total power and fuel capacity are also unrecorded.
Given the boat’s established role as a racer, the interior is best understood as minimal shelter rather than a cruising layout.
Known Limitations
The Martin 243’s known constraints relate to its performance envelope. Its capsize screening figure and limited righting capability mean it demands a crew that understands its racing orientation.
Verdict
The Martin 243 is a purpose-built Canadian ultralight racer, designed by Don Martin and produced in a tiny run of fourteen boats beginning in 1998. It offers a racing-minded owner a stiff, quick fractional sloop, but its capsize and righting figures set firm limits on where it should be sailed.
Pros
- Very high-performance ultralight with a sail-area-to-displacement ratio of 56.32
- Reasonably stiff and stable for its weight class
- Lifting keel provides flexibility for trailering and drying out
Cons
- Poor righting capability after a capsize
- Capsize factor of 2.92 limits offshore suitability
- Accommodation and engine specifications are largely unknown
