the rocna anchor came out best in all these test..
It's not obvious which anchor is the best!!! Why the results of the Hydrobuble are missing?? It was the best results!!!..
Tests have been stopped at about 5000 lbs.. if the tests wouldn't have been stoped what would have been the results then??
May be the results should have been corrected in relation with the size of the anchors, for example, the Fortress tested was much bigger than all others anchors, Same comment for the Rocna which was much bigger than the Spade..
