What does the "Ok" symbol with a ski in hand indicate for a skier?

The "Ok" symbol with a ski in hand indicates approval of the current speed for a skier. When a skier gives this sign, it communicates to other skiers and boat operators that they are satisfied with their speed and are prepared to continue without any adjustments. This is particularly relevant in water sports, where coordination between the skier and the boat driver is essential for safety and enjoyment.

In contrast, the other choices present different signals. For instance, a request for an immediate stop would typically involve a more urgent signal, while a warning of incoming obstacles would require a different gesture altogether to ensure clear communication about potential hazards. Encouragement for faster speed might involve a more dynamic body language or hand signals that indicate a desire for increased pace, rather than simply signaling "ok."
