">>> [size=5]The secret life of anchors[/size] >>>
If you 're like us, every time your anchor drops into the water and disappears, you wonder what happens. Does it flip around? Does it sink into the floor or does it grab something? What happens when the wind shifts? Does the anchor hold in the previously set position or does it move and reset?
Intrigued by these question, Steve Goodwin from SV Panope set out to find answers. He experimented with rigging a float and GoPro camera to a dozen different anchors. Then he dropped each one on multiple types of sea floors with different scopes to see what happened. And "see" is the important part. He even went the further step of simulating 180 degree swings to record what each anchor does in that situation.
Fair warning - starting along this video watching path will melt away hours of your time.
Steve has made all of the videos available on a YouTube Channel. The latest, #56 in the series, is a compilation of many of the other videos. It will give you a great feel for the work he has done on this and can be seen here: https://youtu.be/l59f-OjWoq0
From that video, subscribe to the SV Panope channel to be notified when new videos are submitted or to view the others in the series. There are more detailed videos for each type of anchor.
This type of information collection and sharing is the essence of the boating community. Steve shows no bias for a particular type of anchor. The goal is collecting real information and showing the raw videos. What he has created is a valuable resource for all boaters. Thank you, Steve!"

Thanks for sharing George - indeed interesting viewing, and confirms precisely what we have seen, found and write about!
The guy must have spent ages working on this!

Hi George, That was a fun video. I am curious about why there was no Rocna included in the testing. Maybe I missed something as I tend to go into a bit of a trance after a while. Dick Stevenson, s/v Alchemy

Quite right Dick. Steve 's site carries the comment that he did not test a Rocna because he did not have one!

Hi George, That is a shame. I suspect it would have acted quite like the Spade and the Manson, but it would have been nice to actually see. Dick
