I "inherited" a 30 year old sailboat and with it, I inherited the problems of the former owner. I called Ross at Cranky Amps and he came to see my boat at my marina. He did some troubleshooting... and gave me the options. I hired him, and he was clean and quick. He called after to ensure I was happy and understood how to use the new products... and was even patient when I asked him to "reteach" me.
