What Anchor?

Advice please.
What anchor (type and size) should I have for my boat.
I will anchor in reasonable shallow water although the sea-bed will vary enormously.
The boat will weigh about 3.5 tons and is 9.5m long.
Should I have two anchors?
The boat is not likely to be moored at anchor in adverse weather conditions.

have a look at Spade anchors.
www.spade-anchor.co.uk

They are expensive, but if you have a 30K boat, why risk it with a 20 anchor?

Has anyone else any experience of this product.

Cough, cough, splutter, splutter! If you can get hold of a boat likes Brian's for 30k you'll find you suddenly make a lot of friends on this forum - me included. (That, or you'll get a visit from the boys in blue!)

You're making a good point though.

the books always say that the fisherman anchor is poor but when we were fishing all the time at anchor in strong tides that was the type we used cos it would dig thru weed,hook round rocks and dig into sand. However they do not stow that well. we have a bruce type anchor on one of our boats which is a one piece no moving parts anchor and is excellent. Not keen on CQR anchors as the have a moving part that can trap your (or more importantly "my") fingers. Dont like danforths for the same reason plus they tend to "kite" away as you pull 'em in.

Hmmm. Maybe you get what you pay for.
The Spade aluminium 7.0kg is 219 Excl. Vat.

Hi folks

Umm, a 7.5kg anchor on a 3.5 tone boat sounds light to me, unless its alloy.

I use a 10Kg Bruce on a 7.8M which weights maybe 1.5-2.0 ton

The other big thing to consider is the length & weight if chain.

A smaller anchor with lots of heavy long chain will perfom better then a heavy anchor with little light chain.

If it was me I would go for somthing around 15Kg with about 10M min of 3/8 chain. and the rest on 16 or 18mm rope.

As for two anchors YES, but maybe the second could be smaller, maybe 7.5Kg

My main is a 10kG bruce, 10M 5/16 chain +30M 14mm octoplat.
Second is 5Kg Bruce, 10M 1/4 chain +30M 12mm nylon.

The last thing about anchors is think of the tubes. Their are a few nice good peforming anchors out their which have some sharp points, Fortress, Brittany, Delta etc for example.

I like the ones with big round edges like the Bruce, CQR and other ones that bounce of tubes and not into them

Regards Gary

Sound advice from Gary. Brian you want as much chain to go with your anchor as you can practicably carry - at least 10m of chain.

I'm just rekitting three rescue boats for my sailing club and am unsure what anchor gear to buy. Bear in mind the job of the anchor is quite different to what we might expect of it (ie unlikely to be used), but must preform in an emergency never-the-less.

Space (and weight) are of a real premium, these boats are 16-18ft and have 30-40hp engines.

The operating area is not very deep, so i was thinking 15m rope (10mm) + 5m chain. Not sure of the anchor type - i like the danforth 'coz it folds well!

Any comments?

I'm also replacing the tow bridals and lines. Here are my thoughts:

Bridal - lenght tailored to boat, stainless caribner type arrangment each end with eyesplice onto rope. 10mm octoplat.

Tow-line - 6m of 10mm octoplet, unsure what to have on the ends. Although quick release is a nice idea the weight of a stainless fitting on the bridal is underisable i think. Equally a cariber on the bitter end would be nice but i don't think it's ideal for throwing to a casulity sailing boat (they hurt!).

Again any suggestions invited.
