The support of the seat on the photo is a cheap improvisation and will be exchanged for a more solid model, also of course adjustable in height.
After a lot of fiddling we have fixed the original table with a single central table support (stainless steel) on the hatch of the engine compartment. The counter base of the screw connection consists of a larger aluminium plate below the sandwich of the engine compartment hatch. Table and table leg together are removable after loosening a clamping screw. We were able to continue using all elements of the original Amel 54 table: aft support, side extension and side extension support. To be honest we will replace the original table top with a lightweight top by opportunity as the whole construction is quite heavy.
The hatch to the engine compartment can be opened with the table folded down, whereby the opening angle is somewhat smaller than originally: the table will hit the mast at a certain angle. Alternatively you can take away the table and the hatch will open as usual.
