At the best of times the cables and terminals must put up with a combination of the omnipresent salt atmosphere and vibration the United States Coast Guard requires fuel tanks to be tested at up to 25 G's ; at the worst of times these cables may be totally submerged in bilge water, or dripping with engine oil, or cooked at high temperatures. All too often, salt infiltrates terminals and wicks up conductors, causing corrosion and electrical resistance; vibration causes copper conductors to work harder and fracture; and oil and high temperatures degrade insulating properties, leading to short circuits. As electrical efficiency declines, equipment fails, and in worst cases fires are started. It makes no sense to install high-quality, marine-rated electrical and electronic equipment on boats without at the same time using high quality, marine-rated cables and terminals to power the equipment. In the marine environment, "high-quality, marine-rated" is determined by the following: Tinned conductors, in which every strand of a cable is individually tinned to minimize corrosion.
Installing alternate power sources Installing alternate power sources By Bob Pingel Solar, wind can power a boat at anchor with system that take up less space than ever There is no greater pleasure than anchoring your boat and lingering as long you like. At face value this seems like a simple proposition, but our lives have gotten a little complicated. A crew at anchor will want to run the fridge, music, lights and more, and this all takes electricity. Thankfully, technology has advanced to where these systems can run indefinitely given ample sun and wind. Your time at anchor is only limited by water tankage and the beer in your fridge.
Jack Tyler Taking European AC Power onboard will be an essential capability for all but the simplest boats and crews out cruising today. And depending on how simple or complex your choice, you are likely to find it easier to modify your AC system before departing your homeport, or it might make more sense to await your arrival in Europe before your AC modifications. Can I plug in?
