Voyaging Tip #11 Bridge Clearing by Laser

Make sure there is room to clear the mast and antennas before attempting to pass under a bridge. This is particularly important when the tide is high. Stop the vessel just before passing under the bridge then compare the laser range to the top of the mast with the laser range to the underside of the bridge. There should be an ample difference to allow for clearance of antennas. If there are any doubts don't chance it. Wait for low tide and laser range again to be absolutely sure of clearance.
