Our vision of a “sailing submarine” aka a sailing ship with a submerged hull requires a set of sensors and actuators to compensate the absence of stabilizing buoyancy, caused by minimizing the ship’s volume near the water surface. While the design is supposed to reduce the response to sea state and minimizes the stalling bow[…]

In free-style scale model prototyping one can daydream into that microcosm, where you can do miraculous pointy-headed things you could never do in full size reality. A good example for this is to use air balloons from the jamboree store to level and balance the shiplet’s position and mass distribution inside the tubular ballast tanks.[…]

Inspired by the Dyna-Rigg, designed in the 1960s by the German engineer Wilhelm Prölß, we decided to equip the shiplet with likewise sviveling, but static sails. We will use radio controlled servos to manually rotate the konvex profiles within our pivoted mast supports, also to test detrimental positions and situations. To start with, we use some[…]

Finally the shiplet got painted. Sincere thanks are given to Cadus for providing the space for the paint job and to Tuomo for providing the coloration. Now we are of course really eager, ney, we are thrilled, excited, super curious, on tenterhooks, … (!!!) to find out, if all our calculations and estimations about downforces[…]
