None, it comes down smoothly. I make it pop out when I'm ready. The line needs to be short.

I did experience a very dangerous situation once. When I first installed the mast step, I just inserted it into the mast and used it. It didn´t have anything to keep it in place. But it didn´t really seem that it would get out by any mean. And it worked fine for two or three days, even with some decent wind. Then one day I decided to push the boat to slide it into the water, and I pushed right on the mast base, making it rotate backwards and come out of the mast. I don´t remember if it rotated all the way or not, but by miracle the mast stayed vertical and I could lower it with the help of other people in the beach, without killing anybody..

And last week I was sailing in light wind and saw a shroud hanging free.. fortunately the leeward one.. I managed to keep the boat on the same direction and re-attach it. One of the plates of the adjuster was bent, so it was open like a V. By miracle the pin was still there and I could put it back in place and get a ring from another piece of hardware. All that a few meters from the shore, unable to change direction..

I suppose that the adjuster was twisted when I raised the mast and got bent. Then the ring received too much pressure and was cut. Or maybe it just got out somehow, who knows. Now I have something else to double check after I raise the mast. I wonder if there are transparent shroud andjuster covers..
