The Precision 18 is a 17foot 5inch trailerable sloop drawn by Jim Taylor and built by Precision Boat Works, pairing a shoaldraft keel with a selfcontained centerboard so the hull can be dried out or launched from a ramp yet still stand up to a breeze with 350 pounds of lead ballast inside 1,100 pounds of displacement selfcontained centerboard with lead ballast. Production ran from 1984 through 2019, and roughly 500 were completed. What Taylor delivered is a small boat with the accommodations and rigging discipline of a far larger design, aimed at sailors who want to tow, launch, and camp aboard without stepping up to a keelboat they cannot trail.

Design and Construction

The hull carries a spring to the sheer that reads as attractive rather than utilitarian, and the bow shows a sharp entry that promises a clean parting of the water forward spring to the sheer and sharp bow entry. Beneath that topside, the ballast lives in a shoal keel as lead, and the centerboard is self-contained rather than hinging through an exposed trunk into the cabin. With the board up the draft is just 1 foot 6 inches; with it down the boat reaches 4 feet 3 inches, a range that lets the same hull gunkhole in a creek or windward-tighten offshore. The 7-foot 5-inch beam and 15-foot 5-inch waterline give the modest envelope real stability, reflected in a ballast-to-displacement ratio near 32 percent and a capsize screening figure around 2.88.

Rig and Handling

The fractional sloop rig stands a 22-foot 4-inch mast to a masthead 27 feet above the design waterline, carrying 145 square feet of sail — 85 in the main and 60 in the jib, with a 150-percent genoa option at 72 and a spinnaker equal to the whole working area at 145. End-boom sheeting keeps mainsail control simple, and every control line is led aft for ease and safety, so the crew works from the cockpit all lines led aft for ease and safety. The standing rigging tells the story of a running production change: older boats use fixed-eye forestays and upper shrouds of 18 feet 6.5 inches with lower shrouds of 10 feet 1 inch, while newer hulls adopt a toggle-fork forestay, upper shrouds shortened to 17 feet 10 inches, and lowers at 9 feet 4 inches. The Portsmouth DPN of 99.5 and a PHRF of 282 place the design firmly in the small-fleet racing conversation.

Accommodations

Below, the cabin is no palace but owners report substantially more room than the Precision 16, enough to sit up straight and stretch out for a nap under 44 inches of headroom. A large cooler doubles as the step down into the cabin and handles food and drink for a weekend. Sleeping is arranged as a pair of 68-inch quarter berths and a V-berth whose centerline runs 76 inches and which stretches 81 inches parallel to the hull side; the builder's literature claims room for four. Ventilation is generous, and the cockpit itself is roomy at 76 inches long at seat height. The head is a dealer-supplied Thetford Porta Potti.

Trailer and Ownership

The boat is well matched to trailering life, with a 320-pound trailer riding on 205/65/10 five-lug wheels behind a 2-inch coupler and shipping 86 inches wide. Owners report the Precision 18 is about as large as one would want to keep on a trailer and rig each time out, which frames the ownership model: a launch-and-go weekender rather than a marina-bound 30-footer.

The Verdict

The Precision 18 is a thoughtfully proportioned small sailboat that punches above its length. Taylor's layout gives a trailerable hull genuine overnight capacity, while the centerboard-and-shoal-keel combination removes the usual either-or between ramp launch and windward ability. The led-aft rig and roomy cockpit make short-handed sailing safe, and the construction details — lead ballast, self-contained board, sharp bow entry — speak to a serious little cruiser-racer rather than a bathtub daysailer.

Pros

  • Shoal keel with self-contained centerboard spans 1'6" to 4'3" draft
  • Lead ballast and 32-percent ballast ratio in a 1,100-lb hull
  • Led-aft control lines and end-boom sheeting for cockpit-safe handling
  • Cabin with sit-up headroom, two quarter berths, and a long V-berth
  • Trailerable at 320 lbs with standard 2-inch coupler and 86-inch width

Cons

  • Cabin headroom of 44 inches limits standing comfort
  • About as large as practical for rig-each-time trailer sailing
  • Literature's four-person claim stretches a 17'5" hull
