Hey all, I’m trying to figure out the Hull ID number on an old 1970’ish Nautaline Houseboat. The placard in the engine compartment ((see attached) is pretty beat up. I can do a rubbing of it and probably get the numbers in the lower left hand corner, but I won’t know what they are associated with (ie which one is the hull ID). Any other tricks or resources for figuring this out? Thanks!
