We were fishing yesterday so no dive gear. Also had no buoy to drop the line with. I've never had an anchor stuck like this so I wasn't exactly prepared for it.

I think if I were leaving the boat unattended I would want to know it was there when I surfaced not that I advocate any boat left unattended we always have one boat man at least, anchors are designed to hold some better than others.set the anchor with a trip as said and last man up has a look to see that it hasn't got fast.

As a diver Ive yet to have a boat drift away. Most divers go down the anchor line to check the anchor, if need be I will wrap the chain around a rock. Most divers will only dive a small area around the anchor of around 30-40m in the slackest of tide. I have considered double anchoring and should probably do it in the future.


Didn't you have a gps or phone you could take the position from so you could return on scuba ?

Yes lost anchor location is in the GPS. I'm making plans to go get it.

I'm looking at a grapple anchor for fishing. I might just make one. Lighter and bendable for never stuck retrieval...or something like that

Not used one but use something like this then if it gets stuck the idea is you can pull till it bends and frees it self! Good for fishing on wrecks or reefs not for anchoring up and leaving the boat!

One simple way to do this with the anchor you have (assuming you get it back):

Fishing - shackle the end of the chain to the trip point. Using cotton or hemp cord (or zip tie), secure the chain to the pulling end of the anchor. This works best with an anchor without movable flukes like a Bruce or your Delta, where the chain can be stretched tight from the trip point to the holding end. Then the cord only has to hold against lateral forces, not the main pull.

If anchor is stuck fast to the bottom, secure the rode up tight and then power upstream to break the cord. At least that is the theory. This will require some experimenting to get the right cord and the number of turns through the chain link that will hold when you want it to but break when it has to. You have an advantage being a diver, you can test and observe the anchor with someone topside to run the less interesting part of the testing.

Diving - just move the end shackle from the trip point to the holding end of the anchor leaving the cord out of the system.

I was thinking that a fishing anchor might be worth looking at but they would probably not break out if stuck in a rock reef since the slider does not go all the way to the retrieval point in most anchors:Example And I am not sure that the shackle would reliably slide up the stock reliably.

I've never done it, but a buoyed retrieval line as mentioned above is the other option. To me they seem more trouble than they are worth, but I have never lost an anchor (knock on wood).

yeah, the recovery line option seems like it's just one more thing to get in the way, I like to keep it simple.

you have jogged what passed for a brain in my head, I could just make some quick modifications for fishing. I have a burly swivel attached to the shank end so I can't move it easily but I could just run the chain back to the retrieval point and slap a second shackle on there. I could probably just use it that way (backwards) for fishing, I don't need super holding power. or I could run it back up the horn and zip tie next to the doubled up chain.

I have a pile of stuff coming from Amazon, new delta, grapple, extra rode for the grapple, new thimble for the old anchor line. If I retrieve my lost anchor I'll send it all back

I have a giant (military issue that came with the boat) and little danforth I can use for the retrieve. I'll have a crew on the boat so I don't have to worry.

Jason, when you saw Delta anchor, that's a plow right? As others have said, Bruce is used by most I know. And rather than zipties, they use relatively heavy gauge metal wire. It will eventually trip, but seems a little more substantial than plastic?

I really like CaptnRoy's idea. Captroy, does the extra line out cause hassles with tangling or wrapping in kelp?

I've used Danforth on boats with no trouble also.

No, the buoyed tagline isn't a problem at all, firstly, it's much shorter than the regular anchor line, just long enough to let the buoy (small fender) reach the surface...

And you toss the buoy & tagline in the water first and then drop your anchor in, so the tagline and anchor line don't ever have a chance to tangle...

Pretty simple and time-tested....
