San Juan 7.7 Buyer's Guide
The San Juan 7.7 is a 25-foot-ish fractional-sloop from Clark Boat Company, designed by Don Clark in the early eighties, with a solid fiberglass hull and a roomy cabin for her length. On the used market she appeals to a buyer who wants low upkeep and easy close-quarters handling rather than a steadfast offshore tracker.
Layouts on the Used Market
A shopper should expect the standard Clark hull: a beamy 9.5-foot body on a 25.75-foot deck that ranks as roomier than almost all peers. The fin keel draws about four feet by load, keeping her eligible for shallow marinas.
Equipment and Common Upgrades
With no equipment brief on file, the only hard references are the original rigging specs. A buyer should check that halyards (mainsail, jib, and spinnaker) are 24.2 meters by 8 mm and that sheets are 10 mm in the lengths given for the boat, since worn or wrongly sized running rigging is the most likely thing to need immediate replacement.
What to Inspect
The 7.7 has no structural or osmotic defects, so a viewing can focus on the two design traits that shape ownership. The fin keel gives up directional stability next to a long keel, so sail the boat or watch her on a mooring and confirm she does not wander excessively or feel twitchy on the helm. The rig is significantly overrigged for the class, so inspect mast, chainplates, and deck reinforcement for any sign of being worked hard by the large sail area, and verify the standing rigging matches the 8 mm halyard and 10 mm sheet sizes.
Availability and Buyer's Takeaway
Before you commit:
- Confirm the hull is sound fiberglass with minimal seasonal wear
- Sail her to check fin-keel wander on the helm
- Verify rigging sizes against original 8 mm and 10 mm specs
- Check the overdriven rig has not stressed chainplates or deck
