When I first joined the WhatsApp Knysa group, there was a lot of discussion about chain hooks. I don’t remember what people were recommending, but we were just at the Annapolis sailboat show, and saw the Mantus M3 chain hook.
It’s a beast, and it won’t come undone. We are ordering one for our 550.
We have given up on anchor chain hooks. After looking at them in quite a lot of detail, they are far too complicated and prone to coming off.
Our solution? A simple D shack through the chain to the snubber. We use a galvanised d shackle, as it’s going onto a galvanised chain. … and we have dropped a few…
It sure is a beast … That said I prefer there M2 hook … except for the awful rubber strap locking system which I replaced with a velcro strap which last between 3- 5 months and then i just replace it with another one and then redo the velcro on the old one and its good to go again! … Just make sure you rotate the locking pin correctly as it looks like the same locking system they use for their mooring ball bridle. Now that i think of it you can now probably use your M3 for both your chain and mooring ball … which is a bonus!! We really like the mantus products and lots of their stuff.
