What makes this boat special for us

While we cut our teeth sailing dinghies and monohulls on the San Francisco Bay, we decided that a catamaran is what we wanted to cruise aboard full-time. Sailboat design are a series of trade-off. We prioritized on protected helm, single handed sailing, build quality, and off-grid redundancy; over a versatile sail plan, helm visibility, and interior finishes.

Protected helm for single-handing

After several offshore passage on catamarans with either exposed outboard helm, or an elevated sport helm, we realized we wanted a helm that's located low and centered. Aboard the cockpit of the 1370, a single crew can trim and reef the jib and the mainsail from the protected bulkhead mounted helm. The trade-off is the reduced helm visibility which we plan to augmente with low-light and thermal imaging cameras.

Construction method

The hull is vacuum infused vinyl ester resin on PVC foam core using hybrid e-glass and carbon fiber. The carbon fiber bulkhead is tabbed and glassed onto the hulls. The interior furnitures modules are bonded and glassed. This results in a generally stiffer and more rigid build with lower displacement, as compared to comparably priced production catamaran. The trade-off is a relatively spartan interior.

The boat is equipped a 16kWh lithium bank charged with 2.3kW solar on a large coachroof with built-in rain-catchment system. A pair of 2.5kW alternators will quickly top off the battery as a backup. A 40GPH DC watermaker with easily sourced parts will supply additional freshwater. An all-electric galley is paired with an outdoor gas bbq for cooking. All systems are designed for extended cruising with backup systems in case of failure.
