Seems reasonable, but the logic would lead to not allowing ANY helm changes during a race. Not unreasonable for buoys, but potentially problematic for longer stuff.

The second you can take that skipper off the helm at all, you have a potential significant advantage, with no way for monitoring.

Just thinking out loud ....
