问题 Boaters will see advance warning of a storm if they know what to look for in the clouds. If there is a high cloud formation with a dirty bottom and a tall, stringy top, a storm is on the way. In that case, it is important not to try and outrun the storm but to head for a protected area. If a boat does get caught in a storm, a bucket or any kind of drag should be attached to the anchor line. As long as the occupants sit or lie on the bottom of the boat, they should be safe. Many people have fallen overboard and drowned because they stood up, swung their arms, and shouted for help.
