It's written as decimal so 13.6' is 13 6/10 feet. If that's 13' 7.5" then
you're good to go. It is NOT 13' 6"...

I am looking for information on how rig dimensions are written.

I see on the rig layout for my own boat that the J=13.6' and I=44.1'
does that mean 13'6" and 4' 1" or 13' 7.2" and 44' 1.2"?

Thanks for your help,
