There is no doubt that the shiplet’s central submarine hull – a drain pipe – needs some face lifting for the next iteration of the protoype. On its topface we add another tube as a lifting body, which also hosts the carbon-fibre slats that will connect to the side tubes and mount the fin stabilizers. The removable nozzles at nose and tail get vertical fin-formed pylons to connect to the deck and a nice portwhole at the fore to host an under water camera.
