DRAINAGE SYSTEMS
7.1 General
All water is drained by gravity to overboard thru hull fittings located in the hull sides above the
waterline. The drain thru hull fittings are equipped with PVC ball valves that are always open under
normal operating conditions. All drains, including the cockpit scuppers, are connected to the thru
hull valves. In the event of an emergency, the valves can be closed to prevent sea water from
entering the boat through the drainage system. It is important to check and operate the drain valves
at least annually to make sure they are in good condition and operating properly. You also should
check the drain system frequently to insure it is free flowing and that the hoses on the thru hull
fittings are secure and not leaking. Please review the drainage schematic to become familiar with
the location of the thru hull drain valves.
SITUATIONS REQUIRING ONE OR MORE DRAIN VALVES TO BE CLOSED CAN BE PO-
TENTIALLY DANGEROUS TO THE BOAT AND YOUR CREW. IF THIS OCCURS, DISTRIB-
UTE PERSONAL FLOTATION DEVICES TO THE CREW AND TAKE ALL NECESSARY
SAFETY PRECAUTIONS, INCLUDING NOTIFYING THE COAST GUARD, UNTIL THE PROB-
LEM IS FOUND AND CORRECTED.
