Oyster SJ35 Buyer's Guide
The Oyster SJ35 is a Stephen Jones–designed IOR ¾ Tonner built by Oyster Marine between 1983 and 1985, with just twenty-seven launched. On the used market she presents as a rare, race-bred 35-footer: fast in light air, tightly built, and far from a typical cruiser. Anyone inspecting a specific hull should understand both her racing origins and the practical limits of a 40-year-old fibreglass racer.
Layouts on the Used Market
The SJ35 was offered with two cabins and berthing for eight, a high guest count for a 34-foot-8-inch hull that reflects her early-eighties dual-purpose brief rather than cruising comfort. Each boat carried custom joinery, so interior finishes vary hull to hull. With a beam of 11 feet 5 inches she is roomier than most similar racers, but the low Motion Comfort Ratio of 17.4 means the accommodation was never engineered for soft motion offshore.
Equipment and Common Upgrades
A buyer should treat rig and systems on each hull individually where no upgrade history is known. The original fractional sloop rig carried about 563 square feet of mainsail-and-jib area anchor, with halyards near 109 feet and sheets around 35 to 87 feet depending on position. Any buyer should verify the actual winches, sails, and electronics fitted rather than assume a standard inventory.
What to Inspect
Published draft varies with load from about 6.6 to 6.9 feet per one review, while the builder states ~6.3 feet — sources differ, so confirm the keel-and-rudder geometry and the fin keel root for signs of stress or previous repair before purchase. The hull is solid fibreglass; inspect for prior collision or grounding damage given the deep draft. With only 27 built and a 1983–1985 build window, verify the hull number against the known production run and check the custom joinery for water ingress or delamination in a boat now decades old.
Availability and Buyer's Takeaway
The SJ35 appears only rarely for sale, so buyers should watch for the occasional hull reaching the brokerage market.
- Confirm hull number against the 27-boat 1983–1985 build run
- Inspect fin keel root and rudder for racing-damage repairs
- Check custom joinery for damp or delamination
- Verify actual rig, sail, and electronics inventory on the hull
