G'Day Rafael, If I've understood correctly the axis of the propellor is at right angles to the length of the boat like a bicycle not like the prop on a plane! Does it matter which direction you turn the propellor? Is the lean turn a coriolis effect? Also are the points at bow and stern on the axis (coaxial) with the tubular hull? Would love to see pictures of this. Certainly food for thought - thanks!!
