58-Metre American-Built Support Platform — Explorer Conversion
190 ft (58 m) · North American Shipbuilding · Built 2000 · ABS DP-1
129 × 35 ft of open working deck rated for 1,300 long tons of cargo — the blank canvas for a beach club, garage, tenders and a submersible.
Twin Ulstein props and a 1,200 BHP bow thruster on a DP-1 system — hold station over a dive site or tender launch.
ABS ✠A1 / ✠AMS classed and loadline-certified, built to USCG Subchapter L — a proven, ocean-going supply hull.
A Bassan & Benedetti conversion concept already drawn — two new superstructure decks, owner's suite and beach club.
A young, American-built supply vessel (2000) with a wide clear deck and DP — a manageable, cost-effective route into a global explorer yacht.
Standard capability is built into the hull today; optional systems are engineered in during conversion.
The Yacht Channel · Project Atlantis — the platform and the conversion brief
Bassan & Benedetti have already sketched the conversion: two new superstructure decks added to the proven supply hull, hosting owner and guest interiors above a full-beam beach club and a working deck built for adventure.
The hull, machinery and class are proven. The conversion adds volume and finish for owner-standard global expedition service. In outline, the concept includes:
Conversion concept — Bassan & Benedetti Yacht Architecture & Design. Indicative scope; final arrangement to owner specification.
The supply hull as she operates now — bridge, machinery and accommodation already built to commercial ocean standard.
Detailed specifications, the general arrangement, the Bassan & Benedetti conversion concept, pricing and the complete gallery are released to registered principals. Register your mission brief — it goes straight to Paul M. Madden.
