My last boat had roller furling genoa. Now I find myself working to feel safe at the bow for sail changes with hanked-on sails. Question is, what do you do to stay stable, while still having two hands to get the sail hanked-on? I have a bow pulpit and single lifelines that attach to the base of the pow pulpit.
On our recent Gulf race, a crewmate and I went to the bow in some relatively bucky seas (5'-6') to change out the headsails when the wind came up. We were short-tethered into jacklines and on our knees and did okay.
However, we weren't dealing with any big water over the bow - which would have been a very different story I'm sure.
