Anchor Roller Test Lab: Final Results

Well, here it is. This is the geometry data from the mock up testing finished last weekend. I will let the picture speak for itself. Turns out things could be simplified from the initial drawings I put together. Only the aft roller need be adjusted. I guess this why one does experiments and mock ups.

The aft roller positions will stow all four types of these anchors and will self-launch when released.

Also, the Windline rollers used in the mock up will pull through a 3/8″ chain, with a standard galvanized shackle attaching to the anchor shank, without difficulty.

    RJ, You have done a great job! It's great to see that I am not alone in spending time and effort to get it right.
    I am not working to suit all types though, just one, Rocna, but at least three different sizes which means roller adjustment fore and aft. The I just have to build the stern set up.

    Thanks Tom,

    You know, if you stare at something long enough the obsession sets in.

    I think you know what I mean! lol!

    Excellent empirical testing, RJ! You've saved yourself a couple frustrations repeated hundreds of times and I appreciate your generosity in sharing your knowledge gained.
    Cheers to your new roller!
