I am trying to find out what is the BOTTOM PLATE thickness of my Aluminum 1975 Roamer 60'... I've read somewhere that the side plates are 3/16" of 5086 Alum. and the bottom plate was 1/4" of the same on smaller model Roamers but I don't know if the same thickness were used for the Roamer 60' or not? Question was raised by USCG inspection. Any quick help is appreciated. [Email and Phone nr are deleted, use PM!] Thanks in advance and Merry Christmas all!
