The Mantus M3 chain hook is the piece of hardware connecting your snubber or bridle to your anchor chain — and unlike a plain chain grabber, it actually stays there. We've run this one for two years of daily anchoring, and it's been a massive upgrade over both the standard hook it replaced and the older Mantus we used before it. GoodKit-recommended, no hesitation.
What a chain hook is supposed to do (and usually doesn't)
When you anchor, you take the load off the windlass by hooking a bridle onto the chain and cleating it off. The hook has one job: hold on. The trouble with a standard grabber is that the moment the chain goes slack — the boat swings, a gust lets off, the bow drops into a trough — the hook can fall right off. Now your bridle is dangling, the load is back on the windlass, and you may not notice until something has already gone wrong.
The Mantus solves that. It latches around the link and stays latched even when the chain is completely unloaded. It does not fall off. That's the whole point, and it's worth the price of admission on its own.
Beefy, secure, built to last
It's a serious chunk of stainless — about three pounds of heavy duplex steel. After two years in salt water, ours shows no wear. Against a standard grabber it's not a close call; against the previous Mantus hook it's still a clear step up. If you anchor regularly, this is the upgrade you make once and never think about again.
The one quirk — and the fix
Honest note: it can be sticky to open, mostly after sitting underwater in one anchorage for a long stretch — salt and a little growth stiffen the latch. The fix is easy: squeeze the clamp arms together while you pull the pin. Tension comes off the latch and it pops open without a fight.
The bottom line
At around $129 it isn't cheap, but a chain hook is a safety item — the one thing keeping your bridle on the chain while you sleep, right alongside a good anchor alarm. The M3 does that job better than anything we've used, it's built to outlast the boat, and its only downside has a two-second workaround. A GoodKit pick.
- Latches to the chain even when slack — the bridle never falls off
- Three pounds of duplex stainless, no wear after two years
- A massive upgrade over a standard chain grabber
- Gets sticky to open after long soaks (squeeze the arms, pull the pin)
