For what it's worth, most everyone at the marina where I kept my boat which  
was in a county park had GFCI problems when they first arrive, as did most  
every guest from other yacht clubs. The county specified that all the  electric 
has to be GFCI protected. The actual fix to the problem was  universal. The 
problem is that all the boats with problems had inverters. he  inverters can be 
configured at least two ways. One is for neutral and ground to  be tied 
together, the other for them to be separated. The inverters come from  the factory 
with ground and neutral tied together, this automatically trips the  shore 
power GFCI. I have an Interphase inverter. It has a screw that can go into  one of 
two holes. In one hole the ground and neutral are tied together, in the  
other hole they are not. By going to the hole where they are not tied  together, 
the problem with tripping the GFCI was eliminated. Every boat  that had the 
tripping problem and had electricians come to fix the problem ended  up with a 
similar solution.
