While the hull is still in an upside down position it is a convenient time to make the fillets that supports the horizontal parts like the cabin floor, settees and chart table.
Looking for a material that is able to follow the hull shape and in the same time remains horizontal I found Styrodur insulation foam to be the suitable material. All positions are marked with a laser and the mold is formed by the Styrodur which is supported by temporary pieces of wood. Because of the light weight of the Styrodur it is easy to fix with a 3M spray glue.
Folding strut: to satisfy my curiosity I did a rough alignment check of the folding strut and it seems to be OK (at least at the Port side) A photo is here.
