ditto stern railing
79' H27 here and the stern railing is the same way.. Through bolted through the toerail, one piece stantions with nuts underneath.Even at my size of a wopping 5'10" and 130lbs, these were hard to get at at and so I solicitated my girlfriends daughter to hold the wrench underneath while I performed the duty topside and while I was at it, cured my water leak from aft.Chuck, while I was at it, I had also removed the stern toerail and reseated it, along with the stantions and that seemed to cure all my standing rain water & washing water leaks (so long as you don't point the hose into the vents)..P.S.An 8 to 10 year old kid in the cleared out starboard locker can actually just sit in there and bear with you.
