Below the forward cabin on the Alwest 370 is sufficient space for a sleeping cabin. This was planned for in the original design by the addition of side portlights and an air scoop from the forward deck.
This area can either be twin 5 ft long single children’s berths or an almost queen size crosswise berth.
Headroom is obviously limited, with about 24” from mattress to ceiling above, but with adequate lighting and plentiful air circulation this provides a comfortable sleeping area that does not have to be taken apart each day and does not take away from the other living spaces.
The layout chosen for Catherine Ann is based around a 60” wide by 80” long by 7” deep Queen mattress. This allowed space for storage compartments at the head and the foot of the bed, but required every inch of space right out to the hull skin, to achieve the 80” length along the forward edge. The forward corners of the foam mattress needed to be cut back on the lower side, but the top surface is completely rectangular.
