I agree having owned several 16's that adding a grab rail would be a big f-in PITA to do. Having said that I guess anything could be done using a 7 year old to hold a nut. I've pressed our kids into duty on this stuff many times before. I once had our middle boy wedged in to my Ultra 23 when we were rigging it. It was hot as hell and he swelled up. I had to gingerly pull him out by his feet but we got him back out of there.
So this presents an interesting turn in the 1964 road. The first (3) boats built in 1964 don't have deck grab rails. Both Michael Aronow and Brownie comment on that. Brownie in fact says he was chucked out of a 16 twice because he did not have a rail to grab onto as a passenger.
