Plumbing & Wiring Details..

(All layouts & circuits are under development and subject to change without notice)

Name	Description
Main Distribution	The main distribution of 12volt cabling around the boat with circuit breakers and switches. There are two battery banks one for "engine' and one for "house". All can be charged from either the engine or from solar panels. There is no provision for connection to shore power. A 240volt pure sine wave inverter is included for micro wave etc.
Air Con. Wiring	The Air conditioning has two cables fed through a conduit in the back of the wardrobe. One is a 7-way and one is a 2-way. Connections and colour codes are shown. Some cables are doubled because of the current drawn by the fans vs the current capacity of the wire
Ballast Tank Control	There are two ballast tanks. One forward under the Galley floor and one Aft, under the bed. Each can be "Full", "Empty" or somwhere in between. Indicator lights are provided and switches to fill or empty the tanks as well
Helm Control	There are two helm controls. One in the saloon and one on the flybridge. Each consists of a four-way joystick. Left and right movements steer the boat to Port and Starboard respectively. The "up" or forward position blows the horn. Since only one helm position can be active at any one time, the "down" or back position "claims" control of the helm in case it was previously used from the alternate location
Tank Level Gauges	There are three tanks that have level gauges - black water, drinking water and main fuel. (The removable fuel tanks are not included). Given that the tanks have an irregular shape, a non-linear to linear coversion is required to accurately drive bar graph displays.
Rudder Position Sender/Display	The angle of the rudder, at any given moment, is detected by a set of Hall Effect ICs positioned above a magnet mounted on the rudder quadrant. There are four red LEDs for degrees of Port helm and four green LEDs for Starboard. A white LED indicates Midships. A second complete set of LEDs duplicates the display for the Fly Bridge helm position.
Steering Motor Stall Protection And Rudder Drag Control	If the rudder is stalled hard to Port or Starboard, the power to the servo motor is cut and is only allowed to be re-applied in the non-stalled direction. The rudder drag brake is applied whenever the servo motor is inactive to avoid immediate self-centrering.
