The Cheshire cat helms a boat across a four-dimensional lake. The water's surface has three directions in it, so a turn has a direction as well as a size: the stick is the rudder, right turns right, up turns ana, down kata. The throttle is on the right (E and Q). Round the buoys in order. A boat here heels two ways, so it needs hulls spread both ways: three in a triangle. Behind you, Kelvin's V is a cone, and your slice cuts it.
par: the oracle's time round · difficulty /10: timing, w, rudder and heel (how) · boat: try the catamaran or the skiff on any course · kata
