New of course to this forum and new to boat life also... We purchased a 1980 Bristol 42' in February ... It was in the work yard when we bought it, and of course still is (surprise! surprised!) We are however living aboard, so we can work on it every day. We have much experience repairing/remodeling RV's, but none on boats... We thought our experience would be interchangable.... Found out quickly " not so much!!"... We are familiar with RV plumbing and 12v systems but are completely baffled with most of what we are looking at here!! My "go to" has been the internet for years now, but I'm not finding much of help there... The Bristol 42 is said to be a great trawler, but I can't find any specifics on the water/sewer system... My first question is does anyone know of a source for owners manuals, schematics, floor plan prints?? anything that would help us understand the systems?
