The Precision 15 CB is a quintessential American daysailer that bridges the gap between a high-performance racing dinghy and a stable family cruiser. Designed by the renowned naval architect Jim Taylor, this 15-foot centerboarder was a cornerstone of the Precision Boat Works lineup, engineered to be "small and simple" yet sophisticated in its hull form. Unlike many dinghies of its size that feature a towering, obstructive centerboard trunk, the Precision 15 CB utilizes an unobtrusively low trunk design, which maximizes usable cockpit space. This focus on ergonomics, combined with a relatively wide beam, makes it a preferred choice for sail training programs and families who require a boat that is easy to rig, launch, and forgive the occasional beginner’s error. According to Jim Taylor Yacht Design, the boat was specifically intended to offer a "big-boat" feel with a hull that provides more stability than the typical "tippy" dinghy.

Sailing Performance & Handling

The Precision 15 CB is characterized by its predictable, well-mannered handling, which stems from its generous beam and refined underwater profile. With a fractional rig and a simple three-stay arrangement, the boat is remarkably easy to tune. The centerboard configuration allows for a shallow draft of only 6 inches with the board up, making it an ideal vessel for beaching or exploring thin-water estuaries. When the board is fully deployed to its 3-foot, 8-inch depth, the boat displays respectable upwind tracking and a surprising turn of speed.

Because the hull is relatively light—weighing approximately 600 pounds—it responds quickly to sail trim and weight shifts, yet its flat-bottomed sections aft provide a stable platform that resists excessive heeling. In his design notes, Jim Taylor emphasizes that the boat was built to be "stiff and dry," a departure from the "wet" rides associated with smaller laser-style hulls. While it lacks the raw acceleration of a pure racing skiff, its ability to plane in moderate breezes ensures it remains engaging for experienced sailors.

The Precision 15 was also produced in a sibling variant: the Precision 15 Keel. While the CB (Centerboard) version is favored by those who trailer frequently or sail in shallow bays, the Keel version features a fixed 1-foot, 8-inch lead-ballasted keel. This sibling model offers significantly higher righting moment and is often found in sailing schools where "no-capsize" stability is a primary requirement. Despite the different foils, both models share the same hull and rig, maintaining the model's reputation for balanced helm and ease of control.

The Precision 15 has earned a sterling reputation within the collegiate and institutional sailing communities. It is frequently cited as a "gold standard" for community sailing programs due to its durability. While it hasn't been the subject of a major motion picture, its presence in technical sailing literature and as a recurring recommendation in "best of" lists for entry-level sailors has solidified its cultural footprint in North American yachting. The boat’s lineage is closely tied to the larger Colgate 26, another Jim Taylor design built by Precision, which is the primary trainer for the U.S. Naval Academy.

Known Issues & Buyer’s Checklist

While Precision Boat Works is celebrated for its "quality built-in" philosophy, secondary market buyers should perform a focused inspection on several key areas common to the 15 CB model:

  • Centerboard Pivot & Trunk: Inspect the pivot pin and the trunk for signs of stress or leaks. Because the trunk is integrated into the cockpit floor, any impact damage from striking underwater obstacles can lead to hairline fractures in the fiberglass.
  • Deck Core Integrity: While Precision used quality materials, the deck is a sandwich construction. Check for "soft spots" or delamination, particularly around the mast step and the chainplates, which can occur if the hardware has not been re-bedded over the years.
  • Rudder Hardware: The kick-up rudder is a convenient feature for shallow water, but the hardware and pintles can develop play. Ensure the blade locks down firmly and that the kick-up mechanism is not seized by salt corrosion.
  • Mainsheet Block Attachment: Some owners have reported that the mainsheet attachment points on the cockpit floor can experience high loads. Verify that the backing plates are secure and that there is no cracking in the surrounding gelcoat.

Community & Resources

The Precision 15 benefits from a dedicated and active owner community. The most prominent resource is the Precision Owners group, an informal but technically savvy network of sailors who share maintenance tips and rigging modifications. Technical support and original replacement parts, including sails and hardware specifications, are still managed through Precision Boat Works, which continues to support the fleet despite the cessation of new hull production in 2018.

The Verdict

The Precision 15 CB is an exceptionally well-engineered daysailer that serves the dual purpose of a stable teacher and a spirited performer. Its Jim Taylor pedigree ensures it sails better than most boats in its class, while the Porter brothers' construction standards have allowed the fleet to age gracefully.

Pros:

  • Unrivaled Cockpit Space: The low centerboard trunk creates a spacious environment for up to four adults.
  • Ease of Launching: A light towing weight and simple rig make it one of the easiest boats to move from trailer to water in under 20 minutes.
  • High Stability: The hull shape provides a secure feeling that builds confidence in novice sailors.

Cons:

  • Limited Performance Ceiling: Advanced racers may find the hull a bit heavy compared to modern carbon-fiber dinghies.
  • Centerboard Maintenance: The internal trunk design can be difficult to access for repairs compared to a simple daggerboard.
  • Market Rarity: Because they are highly valued by sailing schools, well-maintained used models often sell quickly at a premium.
