Hi all -I have a few leaking chain plates - probably all of them so I am going rebed them all this spring. I am wondering if I could rebed them while the mast is still up. I would obviously do them one at a time and support each side with a halyard. My real concerns are the side-stays that run all the way up...do you think its safe as long as I support the mast with a halyard to a rail base? I wave a Catalina 30 with 2 lowers and 1 upper on each side along with a headstay and backstay.Thanks in advance.Rob
