1984 Mason Cutter

EXECUTIVE SUMMARY

Tortuga is hull #59 of Al Mason's celebrated Ta Shing–built 43, a heavy-displacement bluewater cutter with the long overhangs, high bow and flowing sheer that made the design a classic. She has been thoughtfully upgraded for shorthanded passagemaking: a 76 hp Yanmar repower, a 2013 rig refit with new standing and running rigging, reefing lines led aft, an electric halyard winch, and a removable inner stay that converts her from cutter to sloop. Freshly detailed and polished, now afloat in Southport, NC, and newly fitted with Velair reverse-cycle air conditioning (2026), she carries 200 gallons of fresh water in stainless steel tanks, shows the care of attentive owners, and offers a proven offshore platform at a compelling price.
