Tartan 37 Blackwatch Ketch
Description
The Tartan 37 Blackwatch (also known as the Black Watch 37), designed by renowned naval architect Ted Hood, was produced from 1965 to 1970 by Douglass & McLeod and Tartan Marine, with 32 hulls built. This masthead yawl (often misreferred to as a ketch due to similar split-rig aesthetics) is a wood-coachroof variant of the standard fiberglass Tartan 37 sloop, offering enhanced traditional styling, stability, and light-air performance for coastal/offshore cruising—sleeping 5–6 in a mahogany-trimmed interior, and valued for its classic lines and seaworthiness.
