There were a couple of sleepless nights last week, as the NW coast was hit with a big SW front. This is the weather Bass Strait is infamous for. Gusts of over 100 kph were recorded in Devonport. It was the first big test for our temporary shelter. Thankfully we came through relatively unscathed. We opted to do inside work as our shelter is open at the ends, and wind blown rain can find its way in. We decided to make a start on the rudders. These are made up of 10 laminations of 9mm plywood, shaped with electric and hand planes into the correct shape. Later the two halves are glued together, encapsulating the 50mm stainless steel rudder posts. They are very solid as they are designed to take some of the weight of the boat, when on the hard. Compared to mono-hulls the rudders are tiny for a 12m yacht (400mm x 530mm). This one advantage of cats. The steering loads are spread between two rudders, and cats by their nature are more directionally stable than monos. The flip-side is that they do not tack as well as monos. However: the ability to have two engines, makes them much easier to manoeuvre in tight confines, such as marinas. Mono’s need forward movement at all times to maintain steerage way, whereas a twin engined cat can turn on her own axis.
