Do you have a photograph of the “Gap?”
I’ve not seen a Bavaria yet that didn't have a helm seat, other than my own B36(2002) for a brief period while it was a charter boat, and during which time one of the charterers had stood up quickly, caught the bench seat which was rested across the gap area. At the time the rope securing had been released while berthed, and had not been tied back on before going sailing. The seat fell down into the bathing platform area of the sugar scoop before falling over side, and at which point the charterers realised that it didn't swim. A new bench seat was ordered from the importer, and the cost was something over £300 at the time. The replacement seat was secured in place with a bungee cord where both ends were permanently fixed to the boat so that it couldn’t be untied or accidentally lost again.
