That is an interesting maneuver…I have a CDI furler with integrated halyard that would be hard to lower under these circumstances…so my choices would be to try and roll it up by hand, or your circle technique. Good one to remember.I’ve seen this method done and then I had a chance to do it myself.
Drive the boat in circles letting the wind push the sail around the furler. It takes a while but it does work.
When the sail is wrapped around the furler, lash it up tight, recover and rewrap the sheets if needed. Correct the issue then unfurl and continue to sail.
Yes. Just do it the old fashioned way and drop the sail.My first go to would be to drop the sail while head to wind. Having completed this maneuver many many times, it is my go to. In high winds, I will be wearing my PFD and be tethered to the deck while working the sail.
In a rush lashing the sail to the lifelines serves. If the conditions are likely to last, and green water is not rolling over the foredeck, then pushing the sail down into the forecabin through the forward hatch is a good trick. If the bow is breaking serious waves, opening the hatch is a no no.
As with most boating challenges there are options that you employ or as is often the case discover, because you now have a need.
