2004 Grand Harbour 58

This 2004 Grand Harbour 58 is a three-cabin pilothouse motor yacht built from fiberglass. Twin 500 hp Yammer diesel engines provide cruising at 9 knots with a top speed of 18 knots. The boat is equipped with a bow thruster, Wesmar active fin stabilizer system, and a Northern Lights generator. An aluminum fuel tank and robust mechanical systems support extended cruising.

The layout centers on a full-beam master suite amidships, with two additional cabins and three heads throughout. The raised pilothouse offers all-weather visibility and command of the vessel. Recent updates to the battery system include dual 315 Ah LiFePO4 batteries on the port bank and dual 200 Ah AGM batteries to starboard, charged through dedicated Renogy DC-to-DC chargers installed in October 2025.

In 2026, the engines, generator, and transmissions received complete oil and filter service. New engine and hull zincs were fitted, shaft seals were replaced with new Sure Seal units and spares, propellers were pulled and refurbished, and rear transmission seals were installed. The Wesmar stabilizers were serviced with new fin shaft seals. Hull and main deck gel coat repairs were completed, and the bottom was refinished with new paint. Electronics upgrades include new Icom and Standard Horizon VHF radios at the helms. The watermaker was updated with new Dow SW-2540 membranes, and various seating was recovered. The battery system was fully upgraded in October 2025, replacing older Crown 6V units with the LiFePO4 and AGM configuration noted above.
