The big Forfjord (65 pounds) with the "Deep Set" test. Except for the last moment of the test, it appeared that the anchor was going to stay put - and it probably would have had the anchor not rolled over.

Note: The pull of the anchor rode remained almost perfectly aligned with the initial setting of the anchor.

Next is the Manson Supreme undergoing the "Deep Set" test.

Unfortunately, great clouds of turbidity obscured much of the action.

Next is the Manson Supreme at the "Sand/gravel" site with 2.5 to 1 scope.

Unlike the "sandy mud" site (which is very consistent), this area is quite varied in composition. I noticed that during the SUPER Sarca test (Video #48) the size of the larger rocks was much larger than other nearby areas. See lower right of this photo:

The seabed in the area of this Manson Supreme test is free of larger rocks and seems to have the lowest ratio of rock/sand of all of the tests at this site. This test was conducted within 200 feet of the above Sarca test site.

Here is the 44 Pound Spade at the sand/gravel site. 2.5 to 1 scope. I timed this test to occur at slack current. This made it easy to conduct the 180 degree course reversal test. Unfortunately, the lack of current caused some turbidity at the end of the test.

Steve, your effort has not gone unnoticed, best 40 minutes spent on my computer in a long time.

Thanks.

 
Great summary video! Thanks very much for all the work that you've done.

Of course we won't mind if you come back with part two, testing more great anchors like the Rocna, Vulcan, Ultra, Kobra, Delta or the Boss :) :rolleyes: :D

Very interesting!

In the video, it looks like the "blob" of mud became fastened to the anchor fluke in front of the shank. That blob looked to be very well attached. Could this blob have been acting as a deflector, and making the anchor behave like a plow (ie. Delta) rather than a scoop?

Full disclosure: I purchased a Rocna over the Manson Supreme partly because I never believed in the use of the rock slot. Instead, I have a trip line attached to the trip spot on the back of the anchor shank. [EDIT] This is the hole above the tandem anchor attachment point that is NOT labeled in the diagram below.

I see that Rocna has modified the design since I purchased mine, and now has two trip line holes drilled in the back of the fluke.
