I know this isn't performance related. But I just got 2000 34 foot Mainship Pilot and the company is out of business and I need to replace the fresh water tank. Was hoping to maybe find someone who may of worked there or is familiar with them. I called Marlow boats who took over Mainship but they were no help at all

Try contacting Scott Franzoni at Marine Specialties at 609-618-8620
He worked for several Boat Builders including Viking and can probably figure out how to do anything.
