I have tried 3 gizmos to attach the bridle to the chain, and all have their plusses and minuses. I'm considering trying a soft shackle, and wanted to see if anyone has had experience with them and how well they work on a boat our size.
I've tried:
Wichard chain hook. Compact, easy to use, doesn't come off, but too light for a 110,000 boat in my opinion. I've heard of them bending on a selene although that never happened to me.

Mantus M2 chain hook. Beefy, strong, but it takes 3 hands to attach it to the chain, it doesn't go through the bow roller very well, and the rubber straps need to be replaced frequently.

Mantus M3 chain hook. Seems pretty strong, fairly compact, but the snap shackle doesn't work well making the pin difficult to pull out. The split ring on mine got all bent and I can no longer use it to pull the pin out.
