Tartan 3100 Buyer's Guide
Shopping the used Tartan 3100 means looking at a Tim Jackett–designed, Tartan Marine–built fiberglass masthead sloop from the mid-1990s, a 31-foot fin-keel boat whose moderate-racer numbers and 40-percent ballast ratio make her a sensible coastal cruiser-racer rather than an expedition vessel. Buyers on the brokerage market will find her almost entirely within the United States, and the usual caveats of a 30-year-old production fiberglass boat apply.
Layouts on the Used Market
The 3100 carries a fin keel and a masthead rig on a 31-foot hull with a roughly 10.9-foot beam, which yields a predictable mid-size interior volume for the class. The boat’s 9,030-pound displacement and 3,600-pound lead ballast imply a solidly built lower hull, but the available material does not describe the cabin in detail.
Equipment and Common Upgrades
Most boats on the market will commonly carry a chartplotter, radar, autopilot, air conditioning, and hot water as factory or dealer-fit equipment for comfortable coastal use. Often-seen sail additions include a gennaker or spinnaker for downwind speed; a few owners have added an asymmetric spinnaker or electric winches as upgrades, but those are less common. A buyer should verify the genoa-sheet and halyard condition given the 96.8-foot 3/8-inch halyards and 31.3-foot 1/2-inch sheets specified for the original rig.
What to Inspect
The measurable figures a surveyor can check against original spec are the rigging lengths and diameters and the immersion rate of about 989 pounds per inch immersion rate; a boat sitting far off her lines may indicate undocumented added weight or tankage. Beyond that, standard fiberglass inspection applies. She is a 31-foot fiberglass sloop whose limits are published facts, not hidden faults.
Availability and Buyer's Takeaway
The Tartan 3100 is typically found in the United States. For a buyer, the practical checklist is short: confirm the masthead rig and fin keel are intact, check the 3/8-inch halyards and 1/2-inch sheets against wear, verify the commonly fitted electronics and climate systems function, and note that a gennaker or spinnaker is a frequent bonus rather than a guarantee. She is a sound Jackett coastal design whose limits — a 2.10 capsize screen and 6.8-knot hull speed — are published facts, not hidden faults.
