Mariner 50 Pilothouse

Mariner 50 Pilothouse

Description

The Mariner 50 is a pilothouse motorsailer (often called the Mariner 50 Pilothouse or Mariner 50 Motorsailer) built by Mariner Yacht Co. (USA) in the late 1970s (e.g., 1979 examples documented in listings), with very limited production (exact hull count low, likely in the single digits to low teens due to the niche market and company history). It features a heavy, fiberglass hull with a pilothouse for all-weather protection and visibility, a full or modified keel for stability and tracking, a ketch or sloop rig (ketch common for balanced handling), and a spacious interior suited for extended coastal or offshore cruising/liveaboard use—known for its sure-footed motoring, dry ride, and comfort in rough conditions, though not a pure sailboat (power-focused with auxiliary sail capability).
