You can snagg your daggerboard or rudder on the rope and tow the bloody thing halfway to the windward mark as long as the bouy itself does not touch you.
Inadvertently snagging an anchor line and dragging a mark is a far cry from swimming underwater and deliberately moving it away from your boat to avoid contact. The first is accidental and cannot reasonably help you. The second seems (at least to me) to be an advantage gained unfairly.
