Chapter 4: The Legal Requirements of Boating
Obstructing Navigation

Vessel operators should always be considerate of other vessel operators even when stopping to anchor or moor.

Floating docks are common in Idaho and are designed for use by ski boats, boaters, and those involved in a boating activity.

Keep in mind that it is illegal to:

• Operate any vessel in such a way that it will interfere unnecessarily with the safe navigation of other vessels on the waterway.
• Anchor a vessel in the traveled portion of a river or channel in a way that will prevent or interfere with any other vessel passing through the same area.
• Moor or attach a vessel to a buoy (other than a mooring buoy), beacon, light, or any other navigational aid placed on public waters by proper authorities.
• Move, displace, tamper with, damage, or destroy any navigational aid.
• Obstruct a pier, wharf, boat ramp, or access to any facility.
• Fail to obey the navigation rules.
• Fish or sunbathe on docks where vessels are being launched or otherwise in use by boaters.

If you are operating a power-driven vessel in narrow channels or on fairways of the Western Rivers and are heading upstream (against the direction of the current), all vessels coming toward you from the opposite direction have the right-of-way and you must give way as necessary to permit safe passing.

Homeland Security Restrictions

Recreational boaters have a role in keeping our waterways safe and secure.

• Violators of the restrictions below can expect a quick and severe response.
  • Do not approach within 100 yards and slow to minimum speed within 500 yards of any U.S. Naval vessel. If you need to pass within 100 yards of a U.S. Naval vessel for safe passage, you must contact the U.S. Naval vessel or the U.S. Coast Guard escort vessel on VHF-FM channel 16.
  • Observe and avoid all security zones. Avoid commercial port operation areas, especially those that involve military, cruise-line, or petroleum facilities.
  • Observe and avoid other restricted areas near dams, power plants, etc.
  • Do not stop or anchor beneath bridges or in the channel.
• Keep a sharp eye out for anything that looks peculiar or out of the ordinary. Report all activities that seem suspicious to the local authorities, the U.S. Coast Guard, or the port or marina security.

In March, 2005, the U.S. Coast Guard officially launched America’s Waterway Watch to encourage the boating public to report suspicious activities in our nation’s ports and waterways. America's Waterway Watch simply asks anyone who works, lives, or recreates on the water to keep an extra eye out for any suspicious activities. Anyone who spots anything is asked to call the National Response Center's 24-hour hotline, 1-800-424-8802 or 1-877-24WATCH. The National Response Center is comprised of 16 federal response agencies that have various skills to respond to different incidents.

To Report Suspicious Activities: Call the National Response Center at 1-800-424-8802 or 1-877-24WATCH

For Immediate Danger to Life or Property: Call 911
