Cabin-Sleeper Conversion
The cabin features the ability to convert the berth
cushions to a sleeper.
Notice there are 3 sets of scalloped cut-out
supports on the inside edge of the berth seat
bases.
PORT
BACKREST
SCALLOPED SUPPORTS
See the photo above showing 2 of the 3 sets of
scalloped supports. There are 3 stainless steel
bars that fit into these scalloped supports to hold
the sleeper cushions. They are located on a rack
in the cabin starboard storage compartment under
the cushion. Note that the bars are all the same
length.
Install each bar into each set of scalloped supports.
Remove the port and starboard backrests from
the bolster by pulling up. Insert them across the
support bars to form the sleeper. The backrest flat
side should be forward.
To convert the sleeper back to the standard cabin
layout reverse the process.
