Electronics Cabinet Carcase

Last weekend, I cut, glued and screwed together the cabinet carcase for what is intended to be “electronics central” for the boat. This cabinet will house the main units for devices that have remote control heads. The main cpus of devices such as computers, radios, etc will be in this cabinet. Freshly assembled. Next, some …

More Batteries!

It has been decided, and executed: the aft-most dinette riser base cabinet will be used to store batteries. As the contents of the cabinet cannot be readily accessed, its storage is best used for occasionally accessed items. It will be used to store two battery banks: Engine Start Bank – the box is big enough for one …

“Upper” Port Side Conduit

Not wanting to waste empty space if I don’t have to, I installed conduit up inside the bulwark (which would normally be empty). There are two runs of one inch conduit, stacked one on top of the other. Both originate from the engine room. The top conduit, runs all the way to the forward anchor …

Considering Design Changes

I think in some post, way back, I stated that we would not have a ‘dedicated’ nav station. Instead, we would have the main dinette double as the nav station. My reasoning behind this is 1) I think a ‘navigators throne’, as they so often seem on boats, is kind of silly. Especially when you …

RFI Gremlins: A Preemptive Strike

On the small boat we run amateur radios, including HF equipment, when on the water. Despite modern radio electronics, HF equipment is very susceptible to RFI (radio frequency interference) generated by all sorts of devices (computers, navigation electronics, refrigerators, etc). With all the modern appliances and electronic doodads that are finding their way onto boats …

BEP Distributed Power Switching

Australian marine electrical equipment manufacturer, BEP, is producing products for electronic distributed DC power switching called CZone. I always liked the look of BEP products. Very clean. This particular system seems different in that it uses NMEA2000 as the primary data buss. Seems every other maker has their own proprietary data wire and protocols. Details …

Playing With Software

Been playing with Maretron’s N2KBuilder program. It is a software package that aids in the design of NMEA2000 networks for boats. Somewhat like a CAD program, you can place N2K devices on the drawing and connect them with cables. The software will tell you if and where there are problems with things like connections, cable …

Wiring Begins…

Not really wiring intended for “voltage”, but wiring nonetheless. This is the wiring for the tank level sending units and RF ground plane. The tanks came with standard WEMA senders with a short pigtail wire with solder tinned bare ends. I extended these with 18/2 wire to the port side of the boat at two …

Gadgets on a Boat

Today, laptop computers, flat screen monitors and large flat screen TVs are becoming the norm in today’s modern household. And, they are finding their way onto boats. Behold a new generation of small, low power, projection units. Just think of all the weight and wiring complexity you could save it you had one of these …
