Lady Geraldine ~ 2003 Sunrunner 3700 Sports Cruiser ~ Gold Coast
Picture this. It's Saturday morning, lines are off, and 640 horses are pushing you out through the heads with nowhere to be and all day to get there. The air conditioning is already running below, the BBQ is packed, and your crew is exactly where they should be.
Lady Geraldine is a 37-foot Sunrunner Sports Cruiser built for exactly that kind of day. Twin Mercruiser V8s, fully rebuilt and with a certified 100-hour service completed in August 2025 by Hope Island Marine Services, a Kohler 240V generator, Cruisair air conditioning, two double berths and a cockpit that was made for entertaining. When the anchor goes down and the teal water comes up around the swim ladder, nobody is going home early.
Over $15,000 in servicing, detailing and mechanical work was completed just prior to listing. She has been compression tested, antifouled, fully detailed and rated above average for her age by an independent marine surveyor. Receipts and Condition Report available on request.

Engine
This vessel is powered by twin Mercruiser 6.2 MPI 8-cylinder petrol engines delivering 320HP each, paired with a stern drive system that reaches a top speed of 29 knots and a steady cruise of 22 knots. Both main engines show balanced usage at 822 hours (Port: M326581, Stbd: M320913), while a Kohler 6KVA generator with 920 hours provides reliable offshore power. Maneuverability is significantly enhanced by a Craftsman 12V bow thruster, and the electrical configuration is supported by three AGM5593 batteries dedicated to engine cranking and the house bank.

Navigation and communication are handled by a reliable suite of electronics, centered around the Raymarine A70D multifunction display. This unit integrates a high-resolution chartplotter, depth sounder, and GPS, providing clear and accurate positioning for coastal or offshore voyages. Complementing the digital systems is a classic Silva Type 100 compass for traditional heading reference. Communication is managed via a GME G-Com VHF radio, ensuring clear contact with other vessels and shore stations.
