Electronics

Back in the day, each electronics unit aboard your boat did what it did, and never the twain did meet. Your depthsounder told you the depth, your radar showed what was around, your GPS told where you were, and so on. Today, of course, most electronics can be connected to onboard networks.

When my flexible solar panel gave up the ghost early last summer, I was surprised at how much motoring it took to replenish our Norlin 34’s two Group 27 house batteries after they’d been run down by a week of sporadic bilge-pumping (caused by a slow leak around the keelbolts, ahem).

In 1982, I mounted four ARCO Solar M-55 monocrystalline panels to a stainless steel frame above the dodger on my Ericson 41 sloop, Wind Shadow. On sunny days during the hours closest to noon, my amp meter indicated an 8 to 10 amp charge. Before and after the midday feast, the flow tapered to 2 to 6 amps.

Back in the 1990s when I was cruising full time and living aboard a 1964 Pearson Alberg 35, my electrical system was dirt simple. I had two 100AH wet-cell batteries, a battery selector switch, a 30-watt flexible solar panel and a multimeter. When I wanted to know how the batteries were doing, I put the

As part of the gradual replacement of outdated systems on our Norlin 34 project boat, it was time to look at communications. As any radio manufacturer will tell you, the problem with VHF radios is twofold: they are inherently reliable, thus tend to be a long way down the list of essential upgrades for owners of older boats. As long as you can use Channel 16 in an emergency or call your launch

A few years ago, I left my boat’s two lead-acid batteries on board over winter. It wasn’t intentional—an early snowfall led me to cover the boat up sooner than anticipated, and I just never got around to taking the batteries off.After three months of freezing New England winter, I suddenly remembered they were still on board. I snuck down to the yard one mild Saturday and hooked the

Having a VHF radio on a boat is always a good idea. It allows you to communicate with other boats, marinas, and rescue services if necessary. I have two on my boat, one a handheld and the other a fixed set. Fixed sets have a maximum radiated power output of 25 watts, while handhelds normally have a maximum output of 5 watts. The more power a transmitter has, the farther its signal can travel. The

As part of a major refit of our BoatWorks Bailout boat, a 1983 Ericson 34, we installed an up-to-the-minute electronics package. It was easier than expected.By Mark CorkeInstalling a new pedestal from Edson gave us space for a number of instruments, with the C80 display taking center stage. The C80 acts as a chartplotter, radar display, and, with optional modules, can be
