2003 GRADY WHITE 330 Express
Here is a check list/procedure list that I use on my 33 Express. If desired, gives you a starting point to make a list for your boat. Good luck!
At Dock:
With shore power connected, switch under rear starboard gunnel must be in the “on” position.
Main Panel In Cabin – Flip on shore power switch (versus generator) when 110 power is coming into boat. Switch on battery charger to charge 4 house/starting batteries if needed.
To use generator, open seacock under stern deck plate, switch on generator option (versus shore power) on main panel, switch on blower on main panel, and start generator with start switch.
To use AC/Heat, generator or shore power must be active, A/C seacock under stern deck plate must be open, flip on AC switch on main panel, and turn on and operate system from control/thermostat panel in the cabin above am/fm radio.
There are 2 master battery switches (in cockpit bulkhead compartment) for four engine/house batteries. Note that when the battery charger main panel switch is on (with shore power or generator) it will provide charging as needed to the house/starting batteries.
When Leaving Boat at Dock - close 3 seacocks (Generator, AC inlet & main bait tank) at stern. Close both seacocks (stock bait tank & head discharge) in cabin floor under rear berth. Switch both master battery switches to off.
When Running:
BEFORE DEPARTING FROM DOCK, ANCHORAGE OR MOORING, MAKE SURE THE STERN LADDER IS STORED ON THE AFT BULKHEAD AND THE GENERATOR AND AIR CONDITIONER SEACOCKS ARE CLOSED.
Before departure, unplug 110-shore power cord and flip switch under gunnel to “off” position. Turn “off” shore power switch on main panel. Turn cockpit starboard battery switch to “1” and port battery switch to “2”. Note - when running, engine alternators will charge all 4 batteries, when battery switches are in the above positions. Note – the 2 port batteries power the port motor; the starboard batteries power the starboard motor, generator and house devices. When anchoring/docking overnight, charge the batteries as full as possible before retiring. Turn off non-essential DC power drains at night, especially the refrigerator. During the night, keep the DC power switch & the cockpit switch panel switch activated on the main panel in the cabin to insure that the bait pumps and the anchor light stay on (both switches must be activated on the cockpit switch panel).
Head use – To discharge toilet wastewater in holding tank, open head discharge seacock and use key operated panel on the head wall to macerate and discharge waste water. Make sure to close discharge seacock immediately after emptying holding tank or seawater will flow back into the holding tank. Note - when running, always close discharge seacock or seawater will be forced into head holding tank and fill it with sea water.
