A boat in a controlling position may drive another boat beyond the mark, out of the zone, and all the way to the edge of the racecourse to gain a tactical advantage.
Kinda like what Jimmy did to Deano last year at Mark 1, then the next race Deano did to Jimmy.
I can remember at N20 Nationals in Pensacola several years back Boog driving Alex/Nigel all the way to a pier on the shore. Nigel was soooo pissed.
