1980 Tartan 37 – Tourmaline

Vessel Overview

Tourmaline is a striking example of the legendary Sparkman & Stephens-designed Tartan 37—widely respected as one of the finest performance cruisers of her era. Elegant lines, responsive sailing manners, and timeless proportions make this yacht as impressive under sail as she is at the dock.

This particular vessel is one of the sought-after deep keel Tartan 37s, offering exceptional upwind performance and offshore capability. Thoughtfully upgraded and carefully maintained, Tourmaline blends classic craftsmanship with substantial modern improvements including a fully renewed lithium electrical system, updated electronics, new canvas, refrigeration, plumbing, and recent rigging upgrades.

Currently moored in Seattle’s Shilshole Bay Marina, with a transferable slip available to the new owner for up to one year.
