Question: 1 / 400

When passing under power lines and bridges, sailboat operators need to be aware of the __________.

Wind direction

Water depth

Masthead clearance

Sailboat operators must be particularly conscious of masthead clearance when passing under power lines and bridges. The mast of a sailboat can be quite tall, and if the clearance is not sufficient, it could result in damaging the mast or causing a dangerous situation by colliding with the power lines. This awareness is crucial for safely navigating under structures, as a lack of attention to mast height can lead to costly and hazardous consequences. Understanding the height of both the sailboat's mast and the bridge or power lines ensures that operators can maintain safe navigation clearances and protect both their vessel and any associated infrastructure.
