The Precision 18 is a 17foot 5inch trailerable sloop designed by Jim Taylor and built by Precision Boat Works. Production ran from 1984 through 2019, with roughly 500 boats completed. Taylor packed the accommodations and organized rigging of a much larger design into a small boat for sailors who want to tow, launch, and camp aboard without moving up to a keelboat they can’t trail.

Design and Construction

The hull has an attractive spring to the sheer rather than a strictly utilitarian profile. Its sharp bow entry promises to part the water cleanly forward spring to the sheer and sharp bow entry.

A shoal-draft keel carries 350 pounds of lead ballast, while the centerboard is self-contained rather than hinging through an exposed trunk into the cabin. This arrangement allows the hull to dry out or launch from a ramp while still standing up to a breeze, with 350 pounds of lead ballast inside 1,100 pounds of displacement self-contained centerboard with lead ballast.

With the board raised, draft is just 1 foot 6 inches. Lowering it increases draft to 4 feet 3 inches, letting the same hull gunkhole in a creek or improve its windward ability offshore. The boat has a 7-foot 5-inch beam and a 15-foot 5-inch waterline. Its ballast-to-displacement ratio is near 32 percent, and its capsize screening figure is around 2.88.

Rig and Handling

The fractional sloop rig has a 22-foot 4-inch mast, with the masthead 27 feet above the design waterline. Working sail area is 145 square feet: 85 in the mainsail and 60 in the jib. A 150-percent genoa option measures 72 square feet, while the 145-square-foot spinnaker equals the entire working sail area.

End-boom sheeting keeps mainsail control straightforward. All control lines are led aft for ease and safety, allowing the crew to work from the cockpit.

The standing rigging reflects a production change. Older boats have fixed-eye forestays, 18-foot 6.5-inch upper shrouds, and 10-foot 1-inch lower shrouds. Newer hulls use a toggle-fork forestay, with upper shrouds shortened to 17 feet 10 inches and lower shrouds measuring 9 feet 4 inches.

A Portsmouth DPN of 99.5 and a PHRF rating of 282 place the design firmly in the small-fleet racing conversation.

Cockpit and Accommodations

The cockpit is roomy for a boat of this size, measuring 76 inches long at seat height. Below, the cabin is no palace, but owners report substantially more room than in the Precision 16. Its 44 inches of headroom allow occupants to sit upright and stretch out for a nap, though not to stand.

A large cooler doubles as the step down into the cabin and holds food and drinks for a weekend. Sleeping space consists of two 68-inch quarter berths and a V-berth. The V-berth measures 76 inches along the centerline and 81 inches parallel to the hull side. The builder’s literature claims accommodation for four. Ventilation is generous, and the head is a dealer-supplied Thetford Porta Potti.

Trailering and Ownership

The Precision 18 is well suited to trailering. Its 320-pound trailer rides on 205/65/10 five-lug wheels, uses a 2-inch coupler, and is 86 inches wide for shipping.

Owners report that the Precision 18 is about as large a boat as they would want to keep on a trailer and rig for every outing. That helps define its ownership model: it’s a launch-and-go weekender rather than a marina-bound 30-footer.

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 avoids the usual choice between ramp launching and windward ability.

Led-aft controls and a roomy cockpit support safe short-handed sailing. Its lead ballast, self-contained centerboard, and sharp bow entry mark it as a serious little cruiser-racer rather than a bathtub daysailer.

Pros

  • Shoal keel and self-contained centerboard provide draft from 1 foot 6 inches to 4 feet 3 inches
  • 350 pounds of lead ballast and a ballast ratio near 32 percent in a 1,100-pound hull
  • Led-aft control lines and end-boom sheeting support cockpit-based handling
  • Cabin has sitting headroom, two quarter berths, and a long V-berth
  • 320-pound trailer has a standard 2-inch coupler and an 86-inch shipping width

Cons

  • Cabin headroom of 44 inches rules out standing comfort
  • About as large as practical for sailors who rig their trailer boat for every outing
  • The literature’s four-person claim stretches the capacity of a 17-foot 5-inch hull
