Safety obligations
The practice of towed sports behind a boat is regulated for safety reasons. Among the rules imposed, one of the main ones concerns the crew. Indeed, while a buoy or a water-skier is towed behind the boat, there must be at least 2 people on board. While the pilot controls the throttle and the trajectory, the crew member must keep a constant watch on the person on the skis or buoy and warn in case of a fall. He or she must also be able to release the trailer.
An exemption is provided for holders of a state water skiing certificate, who can remain alone on board.
In our case, if I do not have a state license, answer C is the only correct answer.
Other obligations should be noted. In the case of towed buoys, the towing vessel must display a 2-meter orange flame. The buoy must be brightly colored and all crew members must wear life jackets. The boat is not exempt from speed limits and must therefore generally evolve beyond 300 meters from the coast. Particular attention is paid to the environment.
