Katana has the same waterline beam as Octave. Canoe body maximum depth has increased by 2.4mm. Maximum cross section area is unchanged, staying at a value that has proven optimal.  Moving some midsection area from the turn of the bilge to the bottom of the hull gives a midsection that returns to being as close...Read More

A sneak preview of our next RM design: Katana. Katana is an evolution of Octave, incorporating improvements in several key areas. The individual changes are small, but sufficiently numerous to cumulatively warrant a new designation. This decision has been made with existing customers in mind as it will give them a clear option when placing...Read More

As mentioned previously, the choice of tooling material and shape depends on the construction process of the parts to be moulded. To decide on construction method we look at the desired properties of the finished product.   The hull can be thought of as a box girder that has to resist global bending loads and...Read More

Graphic visualisation of hull wave height around a candidate shape. These simulations are very intensive in terms of processing power, so must be used selectively to keep time frames realistic. Fortunately we are in good hands. More will be revealed soon.Read More

Just a quick progress report for those of you who are regular followers. Design work is going well with some very interesting insights already in the bag. A promising hull concept has been identified and tests have started on a family of variants.The opportunity came up to run some more advanced simulations than we had...Read More

Having chosen a hull and foil geometry, the next task is to execute the carefully optimised shapes accurately and efficiently. Class rules mandate a minimum overall weight of 75Kg for the complete boat with no other restrictions on material and shape above the waterline.  Keeping weight at rule minimum is very important for performance as...Read More
