1980 Alberg 37 MKII

Spirit is a 1981 Alberg 37 Mk II, a respected bluewater cruiser with the strength and elegance Carl Alberg’s designs are known for. She has been thoughtfully maintained and upgraded, making her a reliable choice for extended cruising or local sailing. Her 30 HP Isuzu diesel shows only 309.9 hours, and recent service included replacement of the rear engine mounts. The Doyle sail plan consists of a roller-furling jib, main with two reef points, and a mizzen, supported by a Harken Mark III furler and updated rigging components. A 2021 electrical refit included a 450Ah battery bank, new cabling, Blue Sea panels, galvanic isolator, Smart Plug, and mast wiring, providing a robust and modern power system. Electronics include an Autohelm 3000 autopilot with spare, Nexus wind instrument, Lowrance sounder, and Horizon Eclipse VHF. For comfort aboard, Spirit carries a Sigmarine diesel heater, Shipmate stove, and Raritan hot water heater. Her ground tackle is equally dependable, with a Bruce anchor, Simpson Lawrence manual windlass, and ample chain and rode. She was most recently hauled and painted in August 2025 with Interlux Micron CRC ablative, and a professional survey at that time confirmed her hull to be in excellent condition.
