Just spent fun time trying to clean my hull from mussel type growth.
We were sailing last week and seemed a bit slow under sail but very slow at our cruising revs when under engine.
I was convinced that the problem would be mainly growth on the prop but found it fairly clean. The rudder had a lot of clusters on it and the hull especially where if shapes down to the prop.
Just trying to get my head around the issue, is there a difference in water flow behaviour and performance under sail or under engine?
