Removing the Stanchion Hold Down Nuts
By the already replied posts, seems that the stanchion bolts method into the deck of your Cherubini 27 is much the same as on my Cherubini 36. There is a small gap between the interior liner and the hull/outer deck. I can reach up and feel/access the nuts from inside. To date, I only have re-done a couple of my stanchions that I knew were leaking deck water inside. The rest: later this summer before the rainy season starts.Useful socket set items to have are extra deep sockets (can't remember the nut size sorry) and several different length extenders (3", 6" & 12" in my case)between the socket and the rachet wrench. Different lengths are useful (actually necessary) because the recess, access angle, and obstructions below each stanchion's deck through bolts is/are different. Getting the nuts back on their bolts from underneath is a challenge. You don't want the person up on deck holding down the bolts to turn them with the phillips head screw driver too much or your newly applied and still wet caulking might get wisked away from around the hole. So instead, its best to keep the bolt immobile and instead screw up the nut from underneath. For the stanchions that I have done, I was able to get the washer and nut on from below without turning the bolt. Getting the washer on and then threading the nut on to the bolt needs to be done by feel rather than by sight and it helps to have long fingers. Have a few extra washers and nuts on hand... In case some fall down between the interior liner and the hull while attempting to thread the bolt. Patience and the ability to resist frustration are other useful tools to have for this part of the project. While threading the nut on to the bolt, you will get caulk on your fingers. Useful to have a roll of paper towels within reach.
