A chart shows 3 ft of water over a sandbar. Which measurement of your boat tells you whether you can cross it without touching bottom?
Beam
Freeboard
Length overall
Draft
Show the answer
D. Draft
Draft is the vertical distance from the waterline down to the lowest point of the boat (often the propeller or keel), so it is the least depth of water the boat needs. Freeboard is measured upward from the waterline and says nothing about clearing the bottom.
A passenger falls overboard while the boat is underway. What should be done first?
Throw a flotation device and keep the person in sight
Jump in at once and swim to help the person
Put the engine in reverse and back toward the person
Radio a Mayday before doing anything else
Show the answer
A. Throw a flotation device and keep the person in sight
The immediate steps are to shout 'man overboard', throw something that floats, and have someone point at the person continuously while the operator turns back. Backing toward a person puts the propeller next to them.
