Anchoring

What weight anchors did you gentlemen get?

I selected the 15 lb. This may seem light but this is a big anchor for it's weight and the recommendation on the Manson website is that it is suitable for boats up to 30ft. This choice was supported by research which indicates that in good ground, with 25ft of chain, the holding limit would be 50 knot of wind provided that the scope was increased to 5:1.

As with all things to do with anchoring there's lots of factors to consider but I feel that there is a good safety margin for conditions I am likely to encounter.

Thanks Keith,

I think I may invest in a new anchor. And your reccomendation sounds good.

Thanks

Phillp,

I chose the 4kg Oceane with 25 ft of 8mm chain and 50m 12mm dia nylon for my main anchor. Just fits in the Mk III locker.

My spare (and kedge) is 5kg Flook.

They both have about 600sq/cm area.

Calculations on Flook website suggest 60 knots for either should be fine.

Certainly 30 knots was no problem at all.

The nylon is magnificant for taking out all shock and I always use 5:1 scope.

Cheers,

Tom

I anchored on Sat night in 6 metres of water and a very light breeze and stuck tight.

But I still think I will get a new anchor.

This thread prompted me to do a little research about these new generation anchors, & its seems there is quite a battle in the marketplace between the Manson Supreme & the Rocna, I read a few reviews & the main complaint was (with both the above anchors), was that they sometimes dragged up 10-15lb of mud on them. however weight for weight, & the fact they apparently set instantly, & will re-set if dragged in a different direction, they do seem worth a look if looking for a new anchor, if I didnt mind spending the price id go for the Rocna, probably the 22lb as the main anchor, anyone got one?
You'd have to check if your bow roller set-up will take the anchor, but there is quite comprehensive info on all those aspects on the manufacturers websites.

cheers

Hi All,

I had an interesting experience this weekend when on anchor in the Camden Haven River.

We had a 20knt NNE at right angles to the 3knt+ tidal flow.

The result of this that SEAKA was doing 360's around the anchor

First I removed the boom tent, no result. Then I closed up the cockpit awning, still no result.

Sitting there with SEAKA going all over the place I wondered if I should heave too!

BINGO, it worked, SEAKA settled down head to wind [the wind being the stronger at that point]
and never moved. Later that night she headed into the tidal flow when the wind dropped.
Tried the helm over the other side with the same results.

I think this was a combination of wind over tidal flow at 90 degrees.

As a post scrip, when I raised the anchor the next morning, I found that it was wraped up in chain from having done those 360's. So the second lesson from this was, if you do a 360 or almost so:-

You should assume that your anchor is fouled by your chain and you should re-anchor

Personally, if the buoy is banging occasionally against the hull that would mean that there is not a lot of wind or tide movement and that you're not stretched tight or going anywhere, unless of course the mooring has broken free and you're drifting with it an unlikely occurrence. After checking that I'm not drifting that would be a perfect way to have peace of mind. The mooring buoy won't hurt the topsides.

the manson supreme, best anchor around, use lots of chain about 6 to 1 and you'll be right in a cyclone!!

Have decided to buy a Manson Supreme.

Will report how I go.
Thanks
