A modular, solar-powered floating home designed for Caribbean cruising. Ships in 3 containers, assembles in 2 weeks, costs 60% less than comparable yachts.
The Caribbean Drifter combines proven marine engineering with modular construction to create an affordable, safe, and comfortable floating home.
Two 40ft modular pontoons provide exceptional stability and shallow draft. The wide beam (24ft) creates a stable platform that minimizes rolling motion in Caribbean seas.
The elevated solar canopy provides 12kW peak power with 40kWh battery storage. Designed for 100% off-grid operation including propulsion and desalination.
The catamaran's wide stance and high bridge deck clearance allow it to slice through short-period waves with minimal motion. Computer work and cooking continue uninterrupted.
Long-period swells allow the vessel to ride up and over gracefully. The flared hull sections above waterline provide increasing buoyancy, preventing sudden drops.
Every dimension and system has been optimized for Caribbean conditions and modular shipping.
Multiple layers of protection ensure your family stays safe, even when systems fail.
Each pontoon has 4 watertight compartments. Loss of any 2 compartments still maintains positive buoyancy.
6 structural beams connect pontoons. Any 3 can support the platform in emergency.
Low center of gravity with cabin weight below waterline center. Cannot capsize in normal conditions.
5ft freeboard keeps deck dry even in 15ft seas with breaking waves.
Two independent 20kWh battery systems. Either can power critical loads (navigation, communications, watermaker).
Two independent motor systems. Either can maintain steerage and provide 1+ mph propulsion.
Watermaker + rain catchment + 200 gal storage + emergency hand pump for seawater.
VHF radio + satellite messenger (InReach/Spot) + cell phone + EPIRB.
Watertight bulkheads limit flooding to 1/4 of one pontoon. Remaining buoyancy exceeds 200%. Platform remains level.
Emergency solar maintains navigation lights, VHF, and GPS for weeks. Manual backup for water. Sea anchor for drift control.
Run before the storm at 2-3 knots. Sea anchor + drogue system. Solar canopy designed to shed wind. Low profile minimizes heeling.
Targeting 60% lower cost than comparable living space in a traditional yacht.

8 pontoon sections, structural beams, deck panels, hardware
Pre-fabricated cabin module (split for transport), interior fixtures
Solar panels, batteries, motors, electronics, water systems
Bolt pontoon sections together using provided hardware. No welding required. Float pontoons individually at boat ramp.
Connect cross-beams to pontoons. Install deck panels. Platform is now floating and stable for cabin installation.
Lift cabin halves onto platform (requires small crane or come-along system). Bolt together and seal joints. Connect plumbing and electrical rough-in.
Install motors, batteries, solar panels, watermaker. All systems are pre-wired with plug connections. No electrical knowledge required.
Test all systems. Sea trial. Safety briefing. You're ready to cast off.
Skill Requirements: Basic hand tools, ability to follow instructions. All specialized work (welding, electrical) is pre-completed at factory. Average handy person can complete assembly with 1-2 helpers.
