2015 Lagoon 450F “Clapotis” — Fully Upgraded & Never Chartered
$525,000 USD • VAT & Mexican Duty Paid • San Carlos, Mexico • Dockage Included
S/V Clapotis — Lagoon 450F, Hull #389
A beautifully maintained, extensively upgraded 2015 Lagoon 450F offered for sale by her private owner in San Carlos, Sonora, Mexico.
Clapotis is a never-chartered, privately owned vessel with a strong maintenance history and substantial recent investment in her electrical and cruising systems. She is USCG documented, VAT and Mexican duty paid, and held in a single-asset LLC.
Perhaps most importantly for a buyer planning to cruise Mexico or the Sea of Cortez, the existing San Carlos dock/slip is included with the sale.
WHY CLAPOTIS?
Never Chartered • Private Ownership • Extensively Upgraded
Clapotis has never been placed into a charter fleet. She has been privately owned and cared for, with significant upgrades made specifically to improve reliability, comfort and off-grid cruising capability.
The 2025 electrical upgrade transformed the boat’s energy system with a 1,600 Ah LiFePO₄ house battery bank and Victron power-management equipment, providing a modern, highly capable electrical platform for extended cruising.
The boat is also equipped with Starlink satellite internet, making it much easier to stay connected while cruising.
DOCKAGE INCLUDED — A SIGNIFICANT VALUE
Finding suitable dockage for a large catamaran can be difficult, particularly for a vessel approximately 46 feet long with a beam of roughly 26 feet.
Clapotis is offered with her existing San Carlos dock/slip.
Current slip fees are approximately $7,920 per year, making the included dockage a substantial practical and financial benefit for a buyer who wants to begin using the boat immediately.
The existing location also provides an excellent base for exploring the Sea of Cortez and the many cruising destinations of the Gulf of California.
MAJOR 2025 ELECTRICAL UPGRADE
One of Clapotis’ strongest features is her substantially upgraded house-power system:
- 1,600 Ah LiFePO₄ house battery bank
- Victron MultiPlus II 3,000W inverter/charger
- Victron SmartSolar MPPT charge controllers
- Victron Cerbo GX monitoring system
- Victron GX display
- Two Victron Orion-Tr Smart 30A DC-DC chargers
- Solar charging
- Wind/hydro charging capability
- Bridgeport Magnetics isolation transformer
This system provides substantially greater battery capacity and modern energy management for comfortable cruising without depending on shore power or running the generator continuously.
CONNECTIVITY
Starlink Satellite Internet
Starlink is included with the boat.
This provides high-speed satellite internet capability while cruising and is particularly valuable for owners who want to work, communicate, stream entertainment, monitor weather or simply remain connected while away from marinas.
SAILS & SAILING EQUIPMENT
Clapotis comes equipped for a wide range of cruising conditions:
- New tri-radial mainsail
- New tri-radial genoa
- Incidence Gennaker
- Asymmetrical spinnaker
The combination provides excellent flexibility for both conventional cruising and lighter-air sailing.
CRUISING SYSTEMS
Generator
Northern Lights diesel generator, maintained and ready to support extended cruising and onboard electrical demands.
Watermaker
Spectra Catalina 340Z 12V watermaker, providing onboard freshwater production and reducing dependence on marina water supplies.
Navigation & Communications
- B&G Zeus3 navigation systems
- B&G V50 VHF
- Modern Victron electrical monitoring
- Starlink satellite communications
ENGINES & PROPULSION
Clapotis is powered by twin Yanmar diesel engines with SD60 saildrives, providing the maneuverability and redundancy expected of a cruising catamaran.
The boat has been maintained as a private cruising vessel rather than operated as a charter boat.
ENTERTAINMENT
The boat includes a Fusion Marine Audio system with JBL amplification and multiple onboard speakers, providing quality entertainment throughout the vessel.

A TURNKEY SEA-OF-CORTEZ CRUISING PLATFORM
Clapotis represents an opportunity to acquire a well-equipped Lagoon 450F with substantial recent investment already completed.
Rather than starting with an older cruising catamaran and immediately facing major upgrades to batteries, charging, inverter capacity, communications and cruising equipment, the next owner can take advantage of the work that has already been done.
And unlike many boats offered for sale, Clapotis comes with existing San Carlos dockage, an increasingly valuable benefit for a large catamaran.
She is ideally positioned for cruising the Sea of Cortez, Mexico’s Pacific coast and beyond, while her size, equipment and accommodations make her equally suitable for extended family cruising.
