The rule is twice round the lake or 20 minutes if other people are waiting.  Only 4 boats on the water at one time – so if you are waiting head over to the launch area so that those already riding know that you are waiting.

If you are out on the water please be polite and don’t keep people waiting – keep your eye on the launch area to see if anyone is waiting.
When returning to the beach have your spotter raise an arm so that a waiting boat knows that you are heading in and can start to lineup for take off.
