Looking for some guidance in adding spray rails to a 1971 20ma

don't. no need. better uses of your money and time. and holes below waterline, and if you don't have access to the inner hull to thru bolt, then your screwing. its not the fun kind of screwing either you'll figure out in a few years. never seen em ever glassed without some form of screw or bolt. it violates the KISS principle. did i say its below the waterline? on a 20 how many bilge pumps u have 1 or 2? 1 is none like they say in some circles.

you have some spray, dress warmer, get grundens, build a console/doghouse. its a 20 footer its gonna bet wet.
