If you are an average boater not living out on the hook and not expecting to anchor out in a major blow of long duration the ultra or wasi ball swivel is probably more than up to the task. As with all SS and metal fittings regular inspection of the swivel or any other fitting on your anchor is a good Idea. Almost everything on a boat can and has failed at some time. That does not mean that part should not be used. The circumstances and the likely hood of failure has to be weighed. Masts fail that does not mean all masts should be deep sixed. Unless of course if you have a trawler whatever that is.
