Mantus Retrieval Hole?

[rgesner]

I'm debating between Mantus and Rocna, and just noticed this difference.

The Mantus anchor website describes the hole in the crown of the shank of the anchor as "Used to rig emergency retrieval line or tandem anchor set up"

Peter Smith's extensive article on tandem anchoring:
Two to Tandem: Maximizing Holding Power by Tandem Anchoring
says:
"Most anchors have a hole near their crown. However, this is not an attachment point for a tandem rode! It is for a trip line. Never use it for the tandem anchor, as it will unbalance the primary anchor when load is applied. It is also frequently not strong enough, intended only to take the weight of the anchor itself. From one cruiser: “I’ve torn the trip hole out of a 110 lb CQR. Mexican panga caught the float and pulled it at about 25 knots. No corrosion, just ripped the shackle right through the steel of the anchor.”

The Rocna is designed with its tandem attachment point low on the shank, just above the fluke. The Rocna also has its retrieval line attachment point on the back of the fluke itself, where it should be more effective.
