Sulfation surprise

by Nigel Calder, Posted June 23, 2008
"The two group 27 batteries on my boat are both four years old. After charging, all cells have a specific-gravity reading of 1.225 +/- 0.005 and about a 75 percent charge.

Unfortunately, there isn’t enough room to install

Go for the green wire

"I’m rewiring my Cal 2-27 and have reviewed the advice given by Don Casey in his Sailboat Maintenance Manual. He mentions grounding the green wire of an AC system to the engine’s ground terminal, but I’m not sure where to put the green wire on my engine, an outboard with an electric starter and a 6-amp alternator. Do I even need one if I install ground-fault circuit interrupter (GFCI)

Beat the Wrap

Many furling gear problems can be traced to one simple cause

By Peter Nielsen

The last thing you want from your furling gear is for it to jam up in a rising breeze – or at any other time, come to that. I must be some kind of roller-reefing Jonah, because it’s happened a few times on boats I’ve been sailing aboard. On two of those occasions, halyard wrap was to blame.
