Recent Service & Refit History

April 2026 · Most Recent Haulout
Full Haulout & Bottom Service — Royal Palm Marina, Fort Lauderdale
Sea Horse was hauled at Royal Palm Marina, Fort Lauderdale in April 2026 — the most recent haulout prior to listing. A comprehensive below-waterline service was executed covering antifouling, corrosion protection, and full anode replacement. Every zinc and sacrificial anode on the vessel was replaced — a critical maintenance item for saildrive-equipped vessels that speaks directly to the owner's diligence in protecting against galvanic corrosion. She is clean, current, and ready for immediate survey and sea trial.

Atlantic Towers Super Sail Arch — Professional Installation
A Atlantic Towers Super Sail Arch ("Tower in a Box") was professionally installed in Fort Lauderdale, Florida — a structural upgrade that fundamentally expands the vessel's capability and offshore readiness. Built from marine-grade Schedule 80 aluminum with a pre-tensioned arch design, the unit is through-bolted at four points with full backing plates and epoxy bedding. It now serves as the permanent mounting platform for Sea Horse's B&G Halo 24 radar, WS310 masthead wind instrument cabling, and the dual solar panel array installed in the January 2026 refit.
