More Zinc Please...

We hauled the boat today and I went up and looked it. Every thing looks great below the waterline, except the zincs are way past gone; (about) 30% left. We have two zincs on the shaft. Both zincs are held on by two bolts and on both one of the bolts (and the nuts holding them in) were eroded away and gone.

I am a little surprised since were are on a mooring and we don't have a a lot of electronics on our boat, standard sailing instruments, autopilot, radar, radios, but no electric head, a/c, winches. We use the boat every weekend and run the motor about 50 h a year and only for roughly 15 minutes to get into and out of the mooring filed. Our mooring field has a lot of boats, but I am no where near a marina.


Add more zincs next year?
Am I having too much stray current and if so, how to find and isolate?
