Kobra II Anchor

[NapoleonDynamite]

 

Bought a Kobra II 14 kg anchor for a 60' narrowboat, it hasn't come with the shank bolt, is that usual, am I supposed to source something suitable?

Also the photo above showing the welds on the underside, is that normal?

Cheers all.

 

 

 

Also, theres 3 holes in the anchor, I've lined the one up that the bolt goes through, what are the other 2 for?

Best have a look on their website, is it second hand?

[Alan de Enfield]

The different bolt holes are to alter the setting angle to make it suitable for different 'bottoms' (sand, gravel, rock, weed etc etc)

 

The hole above the anchor is to attach the trip-line,

 

From memory one adjustment is 30 degees and the other 45 degrees.

 

There is a lot of good info online - look at the manufacturers website or chandlery website.

 

The folding version was altered and only available on the under 10kg anchors as testing showed the Kobra  adjustability was found to be a weakness with heavier boats.

 

The folding version :

 

 

 

 

My Kobra II (note the II on the stock)

My kedge anchor is a Bugel, and the spare anchor a Bruce.

 

 

 

 

In a boat magazine anchor test the Kobra gave the second best performance of all types tested, and was given the 'best value' anchor tested.

Hmm, It's in the shed now, I'll check tomorrow, but it only seemed possible to line up the one hole. The plastimo site doesn't really give much info, says the shank must be bolted before use, but doesn't say if that bolt is included with the anchor. As it's strength is a fairly important part of the things make up, I'd have thought they'd have supplied or stipulated something specific?

I'm struggling to remember if mine has that long cross-bar (welded onto the two flukes)

 

If you look at the picture of the folding Kobra I'm wondering if your was a 'folder' originally that has had the folding mechansim removed.

 

I'm 200 miles away from the boat and won't be going before mid-March, if you haven't got it sorted I'll get mine apart and photo'd.

[NapoleonDynamite]

Don't think it's been modified, better not have been! It's got all the Kobra II stickers on it, the welds just looked more untidy than I'd expect. My main issue is the missing bolt, or not?

Bought online from  a chandlery in Liverpool, which is the other side of the country and they're closed until Monday, guess I'll try them then. Thanks.

It looks like its made of aluminium.

 

Must be the camera effect.

 

 

I know it is galvanised steel but usually this shows up on pictures. 

 

 

 

Welds look a bit crap.

It's surprisingly heavy for 14kg, feels the same as a 20kg sack of coal. Maybe my coal supplier is on the fiddle.

[magnetman]

Also the one Alan de E pictured seems to have a weighted end on the fluke.

Mine has a weighted end to the fluke. I don't like the look of that one, but it is a bit cold and dark outside to take a photo, maybe I will in the morning and post it.

All the above is why I bought the (non-folding) 10kg Kobra -- plenty big enough for a 60' narrowboat, or a 12m seagoing boat as on the data sheet... 😉

I found a place that sold the 14kg one for less than the 10kg one, so I figured if yer gonna have one, might as well have a big un.

I agree, if you can lift it, then it' not too big.

Paid £60 fo my 14kg one about 5 years ago.

I'm reasonably sure one of these anchors tied to the stern line and chucked in will save me in most of my emergencies on the northern Oxford.

Unlikely. That one is certified only to work downstream of kew bridge.

More likely, my knot would come undone and I'd career into the offside bank at 0.01mph and cause untold damage to a twig.

You don't do much river cruising then ?

[magnetman]

Speaking of anchoring there was an anchor failure on a canal quite recently and the vessel ended up across the chanel. Unfortunately it happened when the pound was high. 

 

Owners left to do something else. 

 

The CRT eventually S8 and removed the obstruction to a remote site. 

 

The Boat was called the Ever Taken. 

 

 

This is what the demons at the CRT do. Beware. Get a proper anchor. Wire the shackles !

Really???!!!! 

 

Did the owners have to come back on the ferry? Or the Chanel Tunnel?

It's plummeting now. Stand by for diesel prices to soar....

Nope. Canal boater, moi.

 

CANALWORLD forum IIRC....

 

 

[magnetman]

 

There were arguments around whether to go via the Chanel tunnel or the Boss tunnel.

I use brass wire rather than cordage.

Oh bugger. I've been in the wrong place all this time. Can you kindly direct me to the river world forum?

Sure. Its either...

I use a marine grade soft stainless steel wire, don't know how much it actually does, but the theory is good.

 

I also have a swivel in the anchor chain to stop it getting twisted as the anchor drops.

Opinion of the usefullness is divided but its there, if it does nothing it doesn't matter, it not eating any meat.
