Some technical information .....more to follow at a later time....... updated March 2002
12v electrical distribution panel. 9 fuses, battery monitor. Simple but I am happy with it.
The 12v distribution panel is located on the side of the cupboard, by the stern door (just visible below right).
The water pump (Whale universal), filters and accumulator tank (air filled bottle) are located under the rear step
The pump hunts a little when a tap is only partly on, otherwise no problems.
Electrical cables running front to back of the boat either run along the join between roof cladding and wall cladding (right photo), or between the upper wall cladding and lower wall cladding. Photo left shows some (lighting) cables in plastic conduit. Conduit is essential where cables can come into contact with foam. A further tongue and groove cladding board, suitably cut down in height, covers the cables and can be easily removed for inspection etc.
Other cables are run under the windows. The side cladding protrudes lower so the cables can not normally be seen. These 3 photos are all views of the same area.
On one side of the boat I ran gas and 12v cables. The other side 12v, 240v and water pipes.

This view also show the gas pipe, 30mm away from electrical cables which are in conduit (safety).
View of conduit and gas pipe support.
Cable sizes. I used 2.5mm² cable throughout, except to the fridge and TV where I used 8.5mm². I first thought 8.5mm² unbelievable large, but after reviewing volt drop calculations and fridge supplier instructions you realize how important cable size is. The bigger the better (less voltage drop).
Vehicle Wiring Products at Derbyshire (0115 9305454) produce a well illustrated mail order catalogue. Prices are reasonable and delivery quick. I purchased most of my 12v electrical items from them.
It is surprising how much cable is required. I purchased 2 x 100m drums (1 black, 1 red) of 2.5mm² cable, and have just 15m remaining.
The longer the boat the larger the cable size required as the cable lengths will be longer.
Window Trims
This photo shows finished wood trim around inside of windows.
I made the window trims from two wood moldings glued together, like a picture frame. One hockey shaped molding one oval molding. 1st the outer hockey moldings are secured. Then the inner oval molding. This photo has the top oval missing.
This photo show the two pieces of wood moldings. One Hockey, one oval. Each approx 16mm wide. They are mitered at each end.
Wood Moldings are available all good DIY outlets (B&Q, Wicks etc). Both moldings are available in different sizes, some windows had larger gaps than others, so I used different size moldings accordingly. The bottom quarter round infill is made from a 50mm wide thin molding, then routered to the diameter of the window frame.
