As the light metal hull is reinforced with various frames and stringers, the bulkheads are not load-bearing and therefore only have a separating function. This means that the interior layout can be designed completely freely. As a rule, this makes an aluminium boat almost a one-off construction. Combined with a canting keel, the freedom in the choice of area is also limitless: shallow waters can be navigated, in supposedly full bays you can still find a place in the shallows, or you can lay the boat with the bow on the beach and it can fall dry. Aluminium and canting keels are the supposed domain of the French shipyards Allures and Aubat with their Ovni models. Supposedly, because there are similar products in Germany. In Emden, the Benjamins yacht shipyard produces upmarket aluminium products up to 80 feet. The BM 40 Clipper from Berckemeyer-Design is a new addition to the programme. The ship with the multi-buckling frame has a surprising three rudder blades, which should ensure a clean flow through the propeller. A bathing hatch and equipment rack characterise the look at the stern. The saloon is characterised by the centreboard box, which takes on additional functions as a second kitchenette with washbasin and technical locker. Two comfortable armchairs provide comfort for the crew on longer passages and in the harbour.
