....also if used by the knowledgeable members here there more common usage with encourage more the unaware to use them.
I think I follow what you meant. If one knows what it means and uses the anchor ball, others may follow. Fair enough. However, what value does that provide in actual collision avoidance, beyond compliance. Compliance could also be accomplished by removing the requirement from the ColRegs, at least for any recreational vessel.
No one is likely to find data on this. However, wouldn't we like to know if any collision at anchor could have been prevented by the ball. Seems so unlikely.
Iíve been struck while moored by a 60í charter cat. If that clown (a professional captain) went forward to put up a ball it would have been quite evident to him he had inadequate swing.
I don't know, Out. Seems like a bit of a stretch. Do you sell anchor balls?
Are you saying we can all better tell our swing radius from the bow than we can from the cockpit? I take it this vessel, as would be common for a cat that size, had a remote windlass and didn't already have to go to the bow to deploy or set a snubber. I think 90+% of boaters have to go to the bow anyway.
I've had boats swing into me, although, it's been in a mooring field that went dead calm. Everyone swinging randomly, so nothing anyone could really do but sit in the cockpit, with a beer, and fend off for a few hours. I was also hit at night, by a boat that broke free from it's mooring in a high current area. Did 7k worth of damage, but the offending vessel was unmanned. No ball or light could help.
