1. Which has the potential to cause the greatest electrolytic damage
(pun intended!):

a. 110 VAC line
b. 220 VAC line
c. Satellite dish
d. Phone line

Phone line, I think - it's DC.


2. Whats the difference between an expensive dockside isolator ($$$)
and a hardware store ground fault interrupt circuit breaker?

The dockside isolator doesn't trip when it rains?


3. What's the one thing that can ruin your entire electrolysis
prevention setup?

a. Tying neutral and ground together on the boat.
b. Unbalanced third leg at the marina junction box
c. Adjacent boat having neutral and ground tied together
d. Each adjacent boat using the opposite side of the split 220V.

I'm tempted to think D. My boat might be fine, his boat might be fine, but,
together, they're sucking the lifeblood out of each other.


4. If your dockside isolator trips can you be electrocuted when
stepping aboard a steel boat from a metal dock?

Seems doubtful - the circuit is insulated cable to the isolator, and there
it stops. The metal dock and boat should be at roughly the same potential -
at least very close to ground.


5. Does water moving along a steel hull increase electrolytic action?

Is it salty?


6. What is the airspeed of a laden swallow?

African or European?


7. What is your favorite color?

Depends on my mood. Some pastel shades based on Ultramarine Blue are quite
nice.
