Bridge Clearance - Regal 3300 Owner's Manual

Rules Of The Road

BRIDGE CLEARANCE

Be aware that your vessel requires a specified bridge clearance height.
This height is a measured estimate from the waterline to the top of
the highest object usually the power tower, radar or the masthead light
depending on what tower equipment is installed. All canvas should be
in the stored position. The estimated height can change because of
variances in the loaded condition of the vessel. An easy way to measure
bridge clearance is to have someone place a long straightedge such as a
piece of wood at a 90 degree angle across the highest point of the boat
with the boat in the water. Then with a tape rule measure the distance
straight down (90 degrees) to the waterline. Take this measurement with
the fuel and water tanks 1/2 full and only 1 person besides yourself on
board. This will give you a safe measurement. As your boat is loaded
down with people the bridge clearance will be slightly lower.
Some bridges are tendered. Know and use the proper bridge signals
when approaching these bridges (see Bridge Signals on Page 2-4).
You can also monitor and communicate on channel 13 of a VHF radio
for bridge information in most domestic locals. Other bridges are
marked with a clearance measurement and you are on your own. After
determining your vessel will clear the bridge proceed with caution at a
safe idle speed. Keep your eye on vessel traffic at all times in order to
react quickly. Resume a safe speed once clear of the bridge structure
and acknowledgment of clear visibility.
Use common sense regarding bridge clearance because bodily injury and
property damage could result if a mishap occurs with a bridge structure.
