Our table does not fold down but is does facilitate a double in the main salon
. The settee is L shaped and the table is supported on 2- 2" Ø SS pipes which have a flange which faces the settee and is at the level of the settee "base". The two SS pipes have pipes inside them which have the flange to attach the table top. These two pipes can slide up...and are set at the desired height by sliding in a 1/4" Ø ss pin into one of a series of vertical holes drilled through both pipes (like those extending poles) raising the table height and permitting room for inserting the back cushion which serves to "widen" the berth. A plywood
panel which lives under the settee cushion is removed and then inserted to rest on the two pipe flanges and a long teak
batten at the front edge of the settee. The main support pipes are connected with a pipe and they each have a flange which is bolted through to the floor. The look like an H from the side..with flanges in the bottom to bolt to the sole.
This turns our settee which is about 28" deep to a 48" wide double berth. You can't roll out either! And the table top is still available to put things on.. and the berth is a bit more "private".
It takes no more than 2 minutes to set this up.
The description sounds a bit complicated, but it is a very simple mechanism and we can even remove the table top and leave the base pipes behind... but there is no need to and no need to store the table. You can even have it set for breakfast and go to bed!
I think the boat maker had this fabricated but it is not very difficult to have it made up... a few welds and some drilling and the right size pipes... a piece of plywood
and you don't even need another cushion!
If you are interested I can take some pix and email
you.. Let me know.
