General information of the road” on page 4. ● Stay informed about the weather. Check weather forecasts before boating. Avoid boating in hazardous weather. ● Tell someone where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you return. ● Use common sense and good judgment when boating. Know your abilities, and be sure you understand how your boat handles under the different boating conditions you may encounter.
General information are waterway rules which apply when you are driving your boat. These rules are used internationally, and are also enforced by the United States Coast Guard and local agencies. You should be aware of these rules, and follow them whenever you encounter another vessel on the water. Several sets of rules prevail according to geographic location, but are all basically the same as the International Rules of the Road.
General information Meeting If you are meeting another power vessel head on, and are close enough to run the risk of collision, neither of you has the right-ofway! Both of you should alter course to avoid an accident. You should keep the other vessel on your port (left) side. This rule doesn’t apply if both of you will clear one another if you continue on your set course and speed. Overtaking If you are passing another vessel, you are the “Give-Way” vessel.
General information or trawls are considered to be “fishing vessels” under the International Rules. Vessels with trolling lines are not considered fishing vessels. Fishing vessels have the right-ofway regardless of position. Fishing vessels cannot, however, impede the passage of other vessels in narrow channels. Sailing vessel right-of-way Sailing vessels should normally be given the right-of-way. The exceptions to this are: 1.

Stop engine before refueling. Refuel in a well-ventilated area. Refuel portable fuel tanks off the boat. Take care not to spill gasoline.
General information ● ● ● ● ● dry rags. Do not overfill the fuel tank. Tighten the filler cap securely after refueling. If you should swallow some gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get immediate medical attention. If any gasoline spills onto your skin, immediately wash with soap and water. Change clothing if gasoline spills on it. Touch the fuel nozzle to the filler opening or funnel to help prevent electrostatic sparks.
