Mini Anchors
« on: April 05, 2009, 05:19:14 AM »
I have to buy an anchor to carry in the B 1-2 & want to get one that European Classe Mini safety inspectors will approve.
Have they ever said that an obviously too light, aluminum, 2-3 lb anchor with 10' of chain, for example, is not acceptable?
Some people will want to have the minimum weight to meet the rule.
I want to carry an anchor that will actually hold the Mini in 30+ knots.
I know the weight of the boat & length, (the usual criteria for selecting an anchor) but does windage & the Mini's beam need to be taken into account?
Is a 6lb aluminum with 12 ft of 1/4" chain a good solution?
What are others using?

Just look at Mini Guide Adrian... it's all there. Check here: http://www.classemini.com/downloads/files/45297/

 In E-9 u they say Iron anchor 6kg min or Alluminium alleation anchor 1,6kg min... with 8m of 6mm chain and 25m rope ready to use. ;-)... That's what we are all using. I dont know if it would hold the mini and hope i never have to check.

Actually Adrian, I think you are going to need two anchors ... from the B12 regs:

Two (2) anchors with suitable rodes ready for deployment and stowed in an accessable location aboard the vessel.

Thanks P, for the reference - I did look at the Mini Guide, but obviously not very carefully to the bottom of the page.

Thanks S, I was going to get 2 anchors for the B 1-2, a min wt possible (that will now be the Classe Mini required aluminium 1.6k & 8m, 6mm chain )
and a more 'realistic/safer' one, (my best guess to hold well was 6lb aluminium & 12' 1/4" chain.)
Will you carry the 2 Mini Classe reg anchors?

I want to carry an anchor that will actually hold the Mini in 30+ knots.

Hi Adrian,

I'm anchoring a lot with my ZERO, as I use her for cruising besides racing too.

Initially in 2004 I started out with an 8kg steel anchor, 8m of 8mm chain+25m of rope.
Used this system in sand bottom up to 20 knots.
For more wind, the chain seemed to be too short.
So I changed to 12m of 8mm(!) chain, which was very good for anchoring but way too heavy to carry around on the boat ...

When I started racing later on, I replaced the steel anchor with the (meanhile allowed)
1.8kg Aluminium Fortress FX-7, using the same 12m chain for cruising (and a shorter one for racing).
That anchor is light and small, but it's holding much less than the bigger steel one.
I wouldn't rely on it in 20kt of wind ...
With an 4 HP outboard you and easily pull it out of the ground going backwards.

So finally last spring I bought the FX11 (3.2 kg, 7 lb), which is holding equal to the 8kg steel  anchor.
I did use it anchoring in 31 kts, and it was holding very well, still using the 12m chain.

If you really want to buy only one anchor, and seriously want to use it for anchoring,
I definitely do not recommend the FX-7 but the FX-11 (or equivalent).

The key is a long  and heavy (8mm, not 6mm as required) chain, the longer the better.
So maybe you replace the "racing-chain" with a longer/heavier 8mm one, if you intend to anchor ...

Hi Thomas and others,

In 30 knots what was your anchor line attached to on the boat?
Do you use a bridle of some kind, the aspi base, large cleat or ??
How do you keep the weight down & have a very secure anchor attachment?
