Complete refit of 93 Lund Tyee GS...bonding question

[jlake1958]

greetings crew!
i have completely disassembled my 1850 Tyee GS and ran into something I am not sure about. After removing the deck boards and replacing, I discovered a green wire from the fuel tank sender and it connects to a screw on the metal fuel filler port of the boat. I see that abyc indicates this could be a bonding connection. I am ignorant of bonding and am unclear whether this is indeed used to deal with stray electricity or if it is for some other purpose.
If my boat is always trailered to use it is a bonding system important if the electrical systems are installed to CG and ABYC standards?

Bonding is connecting 2 more item to the same potential.
Grounding is connecting 2 or more items to same earth potential.

Yes, bonding is important while trailering, probally more important when refueling on a trailer vs refueling when at a dock.

Just my opinion, in 2, he is assuming water does not conduct. When the engine is in the water and tin hull is in the water, both the engine and hull are at earth ground potential. They are both in phyicsal contact with ground.

The rest seems accurate.

It may very well be accurate, I wouldn't know, but one thing for sure is...I gotta headache reading all that !! Lol...now then, any questions on machining ??? Lol..
