Are any of you using an anchor?
Hi Locked in. I still haven't dived from my yak - just kayak around usually trolling a handline. However, I do have an anchor and some thoughts about it -- others will probably disagree. Each to they're own.
My anchor is a cheap but good 1.5 Kg K&S folding anchor (grapnel style). I have equipped it with a stainless steel shackle, a weak-link (but tied so not currently "active" -- weak-link: good for angling bad for diving), a short galvanised chain (from a very big shark hook) and a good quality but inexpensive (3 or 6 strand?) sinking, nylon rope - around 6-8mm. Can't recall how long the rope is but its pretty long 30-60m. At the boat end I have a thick bungee the same diameter as the rope (like your surf leash), as a shock absorber -- I had it hanging around for several years. I also have a lobster pot marker buoy (salvaged from the beach) on the end.
HOWEVER, that's OTT and I usually don't carry it because it's too big & too much hassle. That's not good. The usual recommendations for boat anchors e.g. get a big one, use a strong, long rope & chain if you can are all still good -- but I think you can & should scale it down, quite a lot, for a kayak - depending on your plans (if you prefer heavy seas, big heavy yaks, deep dives, etc. adjust accordingly).
Here's what I would do different if I were starting over:
- get a smaller anchor (I certainly would not go any bigger than my 1.5Kg one, which is plenty big enough). The common 0.7Kg size might be a bit small though.
- I'd use a thinner rope, possibly shorter (as I don't dive deep & rope can take up a lot of room). Mil-spec. nylon parachute cord is very strong for its diameter. Miles mentioned you can get a marine version (he used 3mm on his reels). Or RAs cheap, strong poly float line. Something strong & cheap around 4-6mm is probably ideal for a kayak IMHO.
- forget the chain, shackle & buoy (& possibly the bungee), just tie directly to the anchor on with an anchor bend & check the end regularly. This greatly simplifies the rig, reducing bulk, weight & cost (good if you have to abandon it). You can use you buoyancy aid or spearing float instead of the marker buoy, if you need to leave the anchor in place for some reason.
- get a small stuff sack to store it in (e.g. kids swim bags from Tescos £1, or something smaller).
The main advantage of the above would be that it would greatly increase the liklihood that I would carry the anchor & therefore that I would use it.
Just my 2 cents worth.
