The CM 1200 (frequently referred to as the Carroll Marine 1200 or the Nelson/Marek 39) emerged in the mid-1990s as a high-performance racing machine intended to bridge the gap between grand prix custom yachts and the then-nascent one-design movement. Designed by the renowned duo Bruce Nelson and Alan Marek, this 39.25-foot sloop was manufactured by Carroll Marine in Warren, Rhode Island. It was constructed using advanced materials for its time, typically featuring a fiberglass and Kevlar composite hull and deck, often with an epoxy resin system. The model's history is intertwined with the evolution of the IMS (International Measurement System) rule, where it was designed to be a "giant killer" in offshore and buoy racing. While Carroll Marine is often associated with Bruce Farr's designs, the CM 1200 represents a distinct collaboration with Nelson/Marek, yielding a hull that is significantly slimmer and more specialized for upwind performance than many of its contemporaries.

Sailing Performance & Handling

The CM 1200 is an unapologetic upwind specialist. With a deep draft of approximately 8.5 feet and a lean 12-foot beam on some variants (though other sources cite up to 13 feet), the boat is capable of pointing at angles that baffle owners of more conservative racer-cruisers. This extreme windward ability is supported by a fractional rig that many technical observers describe as "overrigged" for its displacement, providing a high sail area-to-displacement ratio (SA/Disp) in the mid-20s. This makes the vessel exceptionally "light" in the hands during 7 to 12 knots of breeze, where it can frequently climb over larger yachts.

However, this performance comes with a steep learning curve. The boat utilizes running backstays, a technical requirement for maintaining headstay tension in its high-aspect rig, which necessitates a coordinated and experienced crew. In light air under 4 knots, owners report the hull can feel "sticky," but it transforms as soon as the pressure builds. Downwind, while the CM 1200 is fast, it lacks the effortless planing characteristics of later designs like the Farr 40; in heavy air, it requires active mainsheet and traveler management to prevent it from becoming "a pig on stilts," a colorful term used by Sailing Anarchy contributors to describe its handling when pushed beyond its stability limits.

Interior Comfort & Variations

Consistent with its racing pedigree, the interior of the CM 1200 is functional and spartan. It was designed with a "firehose-clean" philosophy—utilizing smooth fiberglass liners and minimal wood trim to facilitate easy post-race maintenance. The layout typically provides basic accommodations for an offshore crew, including pipe berths or simple settee berths, a functional galley for passage-making, and a nav station. Headroom is adequate for a racing yacht of this size, but the aesthetic is industrial rather than luxurious.

There is significant variation in how these boats were finished. Some were delivered as "stripped-out" racers with almost no amenities, while others were marketed as dual-purpose racer-cruisers. This "magic size" marketing was noted by the Cruising Yacht Club of Australia, suggesting that while the boat was big enough for offshore comfort, its primary identity remained rooted in competition. The sibling model, the Nelson/Marek 36, shares many design DNA traits but is noticeably narrower and lighter, further emphasizing the design office's focus on speed over volume.

The CM 1200 maintains a presence in the "Hall of Fame" for regional offshore classics. The model, specifically the yacht Raven, is a recorded winner of the Quantum Coastal Cup, proving its mettle in demanding California offshore conditions. It is also a frequent mention in Latitude 38 archives as a formidable PHRF (Performance Handicap Racing Fleet) contender in the San Francisco Bay and Great Lakes circuits.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the CM 1200 with a focus on structural and cosmetic longevity, as these boats were built to be light and fast.

  • Gelcoat Peeling: The most notorious issue with Carroll Marine builds of this era is a poor bond between the gelcoat and the epoxy hull. This often results in the gelcoat cracking or "falling off" in large chunks. Many existing hulls have already undergone a full strip and refinish with Awlgrip or similar paint systems.
  • Running Backstay Maintenance: The rig relies heavily on the runners for stability. Inspection of the tangs, wire/Dyneema runners, and the deck hardware (winches and blocks) is critical, as a failure here can lead to mast loss.
  • Rudder Bearings and Control: While some owners debate the rudder's effectiveness in heavy air, most agree that the bearings should be checked for play. The boat's high-aspect rudder is under significant load when the boat is pressed.
  • Deck Core Integrity: Like many composite racers, the CM 1200 uses a cored deck. High-load areas around the traveler, winches, and stanchions should be moisture-tested to ensure no delamination or water ingress has occurred during years of hard racing.

The Verdict

The CM 1200 is a specialist’s tool—a sharp, responsive yacht that rewards tactical precision and skilled sail trim. While it lacks the "caravan" comforts of modern mass-production boats, its ability to outperform much newer designs on an upwind leg makes it a perennial favorite for the budget-conscious racer.

Pros

  • Exceptional upwind pointing and light-air speed.
  • High-quality Nelson/Marek pedigree at a competitive price point.
  • Durable Kevlar-reinforced hull construction.
  • Proven offshore track record in major regattas.

Cons

  • High maintenance requirements for the running backstays.
  • Known "Carroll Marine" gelcoat adhesion issues.
  • Extremely spartan interior not suitable for traditional cruising.
  • Demanding to sail to its handicap without an experienced crew.
