Interior Layout

A major advantage of the Mainship 40 Sedan Bridge is that this model offers an interior with very few steps or stairs, making her a safe choice for a family with young, active children as well as easy to manage for an older couple. Overall, this is an expansive floorplan for a 40-footer.

Entry into the main salon is just a couple steps down from the cockpit level through a sliding door in the aft bulkhead. There is a large L-shaped settee to starboard, spacious U-shaped dinette to port and the galley is forward to port.

Continuing forward and down one step, you enter a hallway. To port is a guest cabin with bunk berths. To starboard is a large head with a very large separate shower stall.
