Dear psubbers, Some answers to Ian questions... First...ships are build and turned operational at in a bit different way than TV sets or washing machines...UC3 is a whole new design and lots of things must be altered and adjusted during tests that only happen after we start to sail her. Status now is that we are running in her surface engines, and no attention has yest been given to dive controls and or the control of her electric motor. Its all in the engine room - for weight reasons, but not yet connected. Things take time you know... Initial test of the surface engine indicated that its by far big enough with is 56 kW, since at an output in the 15 Kw range we make 5 knots. We have a very big 1.2 meter five bladed propeller, and it it very efficient. The "sink the Freya" mission of august 10 got us sailing some 35 nm, using about 20 liters of fuel. One reason that we canot test the max speed is that we had ( like anybody else building a ship from zero ) to guess the gearing ratio engine to propeller. This ratio depends on a number of parameters such as the hydrodynamic properties of the hull, that canot be calculated by amateurs. Our gues turned out to be to on the safe side, as it is we cant get the engine at full load because the gearing ratio is to high...essentially she is faster than expected, and we need the adjust - its like running a car in the sekond or third gear if you anderstand... Exact same was the case for Kraka. She was adjusted and now runs close to perfect. As it is however we can sail and enjoy going long with a very low fuel expence. We traveled 35 nm ysing 20 liters going 5 kn. We can bunk some 3000 liters and travel...some 5000 nm !
