The naval architect Tom Colvin (RIP) had two 150 lb fishermans with all stud link chain on his junk rigged aluminum 48'r. I think it was 28k lbs. Those anchors flukes buried deep on just about any sand/grass bottom and hooked on rocks. Their weight was a big assist in getting the flukes to dig so deep. I swam on his anchors several times to see how they reacted in storms and hey never budged. He cruised with them all through the islands down to s america and back without problems.
