Great layout for cruising and sailing.

Board from the sugarscoop stepped transoms on either ama. Main cockpit area spans the full 23’ beam. Steering stations to either side of the cockpit, with full controls and navigation equipment at starboard helm. Aft is a traveler, optional netting underneath the integrated stern arch, which supports the solar array. Radar dome and aerials to port. All cockpit and deck areas are self-bailing.

Enter the main cabin areas through the sliding glass doors located forward of the cockpit and to the left of the main helm station.

The main interior cabin deck spans the two amas and allows the living area to be part of the action! At the entrance, reefer/freezer is to port, followed by generous counter space and easy access to port side steering cables. Galley continues across and to port, followed by navigation station, carbon-fiber dinette table and general seating in the main cabin. The amas are accessed by the main cabin area by carbon fiber steps down to either port or starboard.

Port and starboard amas: Forward storage areas accessed via watertight type hatches followed aft to heads with composting toilets and shower facilities. Portside ama has more carbon fiber steps leading up to generous twin sleeping area. Midships on either ama are sinks. Full aft are the master cabins with raised sleeping berths and engine access under each berth.

All systems are readily accessible and therefore easy to maintain!

Note: Starboard forward upper cabin window above the wraparound seating area needs repair/replacement.

Two master staterooms, one in each ama, located full aft. Each stateroom is equipped with generous queen-sized berths.

Access to each engine is below the berths.

Sleeps a total of 6 people in 3 cabins.

MARIANA was built over a 5-year period in Oregon by her owner using Systems Three Silvertip epoxy resin, tri-axial fiberglass and CoreCell foam. Nothing cheap was used in its construction – all epoxy build. Two centerboards are provided under each ama and provide directional stability as well as the ability to beach the vessel.
