We have previously discussed how we have dealt with the design of flow and pressure distribution at the bow. We now look at the critical design of the aft end of the vessel. The flow around the stern is of very great importance as this will influence not only drag, but also the propulsive efficiency of the propeller. In an ideal situation a propeller would prefer to have ‘clean’ water flow towards it without turbulence and at the same speed as the boat is travelling (Speed of

As discussed in previous sections, the ethos of the design of the bow can be seen to be similar to that of a Bulk Carrier, in that both vessels are looking to maximise internal volume, in our case to ensure the largest internal volume for accommodation, in the Bulk carrier it is clearly volume for cargo. Fuel consumption for the Ship Owner is paramount and in our case energy consumption for propulsion is also key - so further parallels in requirement. Using this design approa

We at Floating Ohm, started without a pre-conceived idea of what the hull form should take other than the limits observed in the previous commentary relating to physical restraints and application. In Naval Architecture we use non-dimensional characteristic coefficients in order to be able to compare different sized vessels. One such coefficient is the Froude number (Fn - see note below for the definition) which enables us to compare the hydrodynamic characteristics of differ
