Steps
Choose the Right Vessel
Look for a sailboat 30+ feet or a trawler with a spacious cabin. Prioritize a sound hull, working engine, and good bones over cosmetics. Get a marine survey before purchasing.
Estimated time: 21 days
Hull Inspection and Repairs
Haul the boat and inspect the hull for blisters, osmosis, and damage. Repair, sand, and apply fresh bottom paint. Check through-hulls, rudder, keel bolts, and propeller shaft.
Estimated time: 14 days
Upgrade Electrical System
Install a robust house battery bank (lithium preferred), solar panels, a shore power inlet with charger, and a proper marine electrical panel. Wire for LED lighting throughout.
Estimated time: 10 days
Plumbing and Water Systems
Install or upgrade fresh water tanks, a watermaker (for offshore capability), water heater, and a marine head with holding tank. Add a sump pump and bilge pump upgrades.
Estimated time: 10 days
Refit the Galley
Upgrade the galley with a propane stove with oven, a 12V refrigerator, deeper sinks, and better counter space. Add fiddle rails and secure storage for rough conditions.
Estimated time: 7 days
Cabin Comfort and Sleeping
Replace or upgrade berth cushions with high-density foam cut to shape. Add ventilation hatches, fans, and LED reading lights. Install storage nets, shelving, and organization systems.
Estimated time: 7 days
Safety and Communication
Install or verify fire extinguishers, CO detector, life raft, EPIRB, VHF radio, and navigation lights. Register with the Coast Guard and secure liveaboard marina slip.
Estimated time: 7 days
