MAIN ELECTRICAL PANEL AND SYSTEM
240/120 Volt 60 cycle 3 phase system.
The panel is fed by 2x 100 amp shore cords with Glendening system and two Cat generators
The shore power is fed through a 40 KVA Atlas power conversion system.
The main panel is a split buss system which allows you to run the ship off of one or two cords, one or two gen sets or a combination of them. The generators are sized so that one set can run the vessel under normal use. There is a ground monitoring system integrated into the panel.
The system is backed up by a Trace 4000 inverter system which is fed from a 10 8D battery bank (house system). The bank can be charged via the inverter or the main engines. The inverter feeds selection of house services including all of the refrigerators and freezers on the vessel, selected lights and power outlets through out the vessel. The inverter allows you to go dead ship for over 72 hours giving you the ability to shut down all systems when at anchor or dock and leave the vessel for shore excursions secure in the knowledge that basic systems are operating and all food is being kept to temperature. Should you lose gen power while at sea you have a extended amount of time to bring systems back on line while still operating on selected AC power systems.
The DC panel is separate from the AC panels.
All pump controls are remote located in there own control panels.
A Alfa Laval Model MIB 303 fuel cleaner is integrated into the fuel transfer system and mounted on a drip tray. All fuel can be transferred through the Alfa Laval from and to all tanks. The Alfa Laval system can be set up on long trips to draw fuel from the two main tanks (4000 gal each) to feed the day tank, the day tank will then over flow back to the main tanks to create a continually circulating system of clean fuel and assures you that your day tank is always cool and full. The day tank holds 980 gals and will supply fuel for 44 hours at cruising speed. This allows you to transfer fuel every 24 hours and still have a 20 hours in reserve. The Day tank is set between the main fuel tanks and surrounded by fuel on 3 sides. The fuel in the larger tanks acts as a heat sink to help keep the fuel in the day tank cool and at a constant temperature for maximum efficiency of the engines. The fuel transfer value system is easy to use and there is a tray mounted above it for storage of small items.
There are a total of 5 fuel tanks which include: two main tanks and a day tank in the engine room and also a mid tank and a forward tank. Fuel can be transferred using a 120 vt high speed pump, the Alfa Laval or a 24vt back up pump.

Each anchor has 400' of 5/8 stud link high test chain
There are stainless chain lap guards on the deck with integrated drains and a stainless rub guard on the stem.
The CQR runs centerline forward on the main deck and clears the bulb when dropped or retrieved under normal conditions. The Navy anchor is mounted in a anchor pocket on the port side with the chain running through a 6" stainless tube. This give While both types of anchors work well in a broad spectrum of bottoms this system gives you the choice to pick the best anchor for the bottom as your primary holder, hard sand, better to use the CQR, soft mud like what is found in St Barths use the navy anchor. The fact that one anchor is running off the vessel from a higher position also means there is less of a chance of the chains rapping. The higher CQR is also much easier to run a snubbing line to.
There are 2x port and stb large stainless cleats with two stainless line guides per side.
Both anchors have an integrated fresh water wash down system. The chains are self stacking, the spurling tube is stainless and bell shaped and there is a minimum of 2' drop between the deck and the chain. There is easy access to the chain lockers from the forward crew quartered.
