Suitable anchor for a AI/TI ?

Twice now I have been caught in tidal current whilst needing to deal with a fish (or this time, a seagull that liked the look of my lure & got truly hooked,) but I had no way of anchoring. I have read various reports on the shortfalls of grapnel anchors, but what other options are suitable for use on a AI/TI?

Hi mickeymouse, which size do you recommend?

I reckon the 1kg job will be enough, along with 2m of chain, That's what I am getting for a TI (plus usual addition of rope 4-6 times depth)

I have one of the 1kg Coopers and it seems to work fine.

What Mickey said ^^^

I've got a 1kg jobbie with 1m of chain.

Thanks all for your input. I did purchase a 1kg nylon Cooper anchor & attached it to 2m of 5mm chain & 50m nylon rope. I was very disappointed on my first use of the anchor. It just would not hold on a sandy bottom. A few friendly emails with Cooper anchors convinced me that I had chosen the right anchor & I should give it another go.

Suspecting that a light (too light? 2m of 5mm) chain may have been the problem, I trialled my trailer chain (3m, 6mm). On the next outing, the anchor held beautifully. I anchored in a course muddy/sandy bottom, 15kt wind, 2kt tide. It held so well, I had to really pull hard to get it out! I have since used the anchor in many different scenarios, different bottoms, with fantastic results each time.

So the moral of the story seems to be, with a light anchor, don't skimp on the chain and when anchoring, use a 7:1 scope. (The 3m of 6mm may be over kill, but its what I had).

Thanks Cooper for your support (and offer of 100% refund if I wasn't happy).

I tried to post a reply but it went "somewhere" LOL.

Another way to improve anchoring efficiency is to attach a smallish weight to your retrieval line (connect this to the anchor line outboard of any bow fairlead you are using) and send it 15-30 feet down your anchor line. This will achieve two benefits
* improve the holding of the anchor be effectively lowering the rode angle (imitating a longer anchor rode), and
* act as a shock absorber, softening the pull on either end due to wave action.

Me too with the above advice. These work well without chain and are boat friendly when getting in and out of the hull..Pirate

Those anchors look well built and very portable! Unfortunately, there is no US distributor. Larry Cooper emailed me that he has contacted Hobie but no one has returned his calls. This looks like it would be a great opportunity for the Coopers and Hobie.
