Rules of the Waterways: What Paddlers Need to Know

ALWAYS wear a Personal Floatation Device (PFD) and attach the board to your body with a SUP leash.

Paddle with a friend, don't paddle alone. 

Carry a communication device - marine radio or cell phone - in a waterproof, floating case.

Check weather, tides, currents, channels, hazards.  Know your water before you go out.

BE AWARE of your surroundings.  You may be the only craft on the water or may be sharing the channel with a large container ship, tugboat, sailboat, fishing vessel, motorboat.  Whatever the circumstance, your awareness of other traffic may make the sole difference in the safety of everyone on the water.

Paddlers do not travel as fast as motorized vessels.  Do not assume that you can pass ahead of oncoming boats.  The safest way for paddle craft to cross the path of any other boat is astern (behind it).  Cross another boat’s path as a group, do not straggle across a channel or in front of larger and faster vessels’ paths.

Busy waterways  have lanes of travel - this is ALL of the San Francisco Bay and it’s marinas, channels, estuaries, canals.  Know the area you plan to paddle.  Buoy markers will line a channel on either side, when returning to harbor a boat must keep the red channel markers on it’s right side and the green channel markers to it’s left (Red Right Return).  This will help you know where you should expect larger boats.

The depth of the channel may limit deep draft vessels.  Deep draft vessels cannot maneuver out of these waterways, you can and must stay out of their way.  You should only paddle in a boating channel to get across it.  If you must paddle in a channel stay to the far side, do not paddle in the middle of the channel.  The safest place to paddle is outside of boat channels.

If you do get caught close to a larger, faster vessel get as far out of their way as possible.  Aim for the back of the boat if you are making a crossing.  As you encounter the wake turn the front of your board into the wave, get to your knees if you feel unsteady.  You are much less likely to fall off if you take the wave head on, not from the side or from behind.

In the marina area paddlers do not have the right of way.  As a paddler you must give way and get out of the way of all boats.  This is also true out on the Bay.  Paddlers DO NOT have the right of way.

All paddlers must follow Marina Bay Yacht Harbor and Coast Guard board sport water safety rules.
