I purchased a showboat from Stan in 2019, the boat was constructed in 2017.  Recently when switching the power on in the boat, I experienced an extreme electrical short that caused my cables to meltdown between the batteries.  I fear I was close to having the boat catch fire, I managed to remove the cables from the battery while using fire extinguisher and battling smoke inhalation.  I hired a certified marine electrician, and he found many issues with the wiring including lack of adequate circuit breakers, use of automotive wiring and not marine rated wiring.   He also found GFCI line and load reversed.

I was fortunate to meet and visit Stan and know this is not what he intended for his beloved Rhodes 22, I fear the quality control was absent in his later years.  I wanted to get this information out to owners and suggest you might want to have a qualified marine electrician review your wiring.  Hopefully, my situation was a one-off scenario.
