The 35foot J/35, drawn by the Johnstone name, has been one of the most successful racing boats of its size since the 1980s. Introduced in 1983, it remained in production through 1994, with more than 330 hulls built. Sail America inducted it into the American Sailboat Hall of Fame as one of the most popular onedesign racercruisers ever produced. Despite paying little attention to the rating rules of its day, the J/35 became the most popular racercruiser rated under the IMS rule and a perennial club winner under PHRF.

Design and Structure

Short overhangs make room for a long waterline, while a relatively low, flat sheerline and low cabin house keep the profile sleek. The boat measures 35 feet 5 inches overall, with a 30-foot waterline and an 11-foot 8-inch beam.

Both the hull and deck are balsa-cored, using end-grain balsa between layers of biaxial and unidirectional fiberglass cloth. Tillotson-Pearson International built every U.S. example and was among the first production yards to align fiberglass strands with the load paths.

A molded fiberglass main bulkhead takes the rig loads and provides athwartship strength. Fiberglass floors support the mast step and carry the bolts for the external lead keel. Hulls built after 1988 used vinylester resin in the outer laminate layer and carried a 10-year transferable blister warranty. Buyers could also order new boats with an American Bureau of Shipping certificate.

Rig, Performance, and Handling

A moderate, well-balanced rig sits on a Hall Spars mast with rod rigging. Tiller steering was standard, although some later boats had wheels.

The J/35 balances well on every point of sail and responds quickly to the tiller. It’s also quite forgiving of mistakes by an inexperienced helmsman or crew. With a PHRF rating around 70, it proved 50 seconds per mile faster than a 16-year-old Carter 36. Tony Lush and Francis Stokes also sailed J/35s singlehanded across the Atlantic.

Auxiliary power comes from a Yanmar 3GM diesel turning a standard Martec folding propeller. Originally rated at 22 horsepower, the engine was redesignated as 28 horsepower after 1985. A 20-gallon fuel tank provides roughly 150 miles of range.

Cockpit and Accommodations

Practical Sailor described the large cockpit as principally designed for a racing crew. It also lacks cockpit coamings.

Below, the interior is Spartan by cruising-boat standards. A forward V-berth was optional on early boats. Just aft, the head is to port, with a hanging locker and bureau to starboard.

The saloon has two comfortable settee berths and an optional fold-up table. The port-side galley includes a two-burner alcohol stove and sink. Opposite are an icebox and a chart-table top. Two large quarter berths extend beneath the bridgedeck and cockpit.

Eight opening ports, two hatches, and the companionway admit light below. Even so, some crews find the lack of standing headroom forward of the main saloon unacceptable.

Refits and Ownership

Used-boat shoppers should be aware of the Yanmar’s rating change from 22 horsepower to 28 horsepower after 1985. The standard Martec folding propeller and tiller are keeper items. On boats ordered new with one, the ABS certificate is a useful provenance document.

The one-design class structure keeps spares and tuning knowledge accessible.

Verdict

The J/35 is a purpose-built racer-cruiser that trades creature comforts for speed, balance, and a structurally advanced balsa-cored shell. It suits sailors who want IMS and PHRF competitiveness without a tender, rule-chasing hull form.

Pros

  • One of the most successful racers of the 1980s; a Hall of Fame inductee and an IMS and PHRF favorite
  • Balsa-cored hull with load-aligned fiberglass and a molded bulkhead
  • Vinylester outer laminate and a 10-year transferable blister warranty on post-1988 boats
  • Quick, forgiving helm and a balanced rig
  • Proven in singlehanded Atlantic crossings

Cons

  • Spartan interior with limited standing headroom forward
  • No cockpit coamings
  • Nearly 7-foot draft limits access to shallow water
  • Racing-oriented cockpit and a minimal galley compared with dedicated cruising boats
