Anchor size advice please

So Oceane is better than Spade?

You told me Spade was Rolls Royce but you say Oceane holds better weight for weight ?

Re: So Oceane is better than Spade?

fOR A VERY SIMPLE RAISON..

for the same weight, the Oceane has more than twice the surface area of the SPADE...

But surface area for surface area.. they have the same holding but the Oceane weight is less than half the weight of the Spade.. :0)

Also size for size, the price of the Oceane is about 40% the price of the Spade..

Is it clear?? :0)...

Re: no it\'s not clear.....

You have given us weight and surface area / size and cost as variables - please give the relationship between either of the first pair to either of the second so that we can work out the rest!

Re: no it\'s not clear.....

Don't think it's going to be an easy calculation. Once set the Oceane is going to perform almost identically to the Spade (same shape and size)

What matters is if the Oceane which is lighter will set as well in the first place? I suspect that in soft sand or mud it won't matter a great deal, If a Danforth type will set, so will the Oceane. It's on the more tricky substrates that weight might help, but I'm not entirely convinced that weight is better than a penetrating shape, and they are pretty much the same in this regard

Re: no it\'s not clear.....

Thanks BrendanS for giving the answer..

And you are also right for asking if “the Oceane which is lighter will set as well in the first place?”

They are two possibilities for setting the anchor:
- either static penetration such as the heavy weight of the SPADE anchor tip or also the weight of the big Hall or Stockless anchors from Cargo ship..
- or dynamic penetration like the Danforth or the Fortress anchor.

The Océane use both.. althouh there is no ballast at the tip, the shank is welded, not at the back of the anchor like most competitors, but onto the tip.. this give two advantages: first a very strong tip (the part of the anchor which works the most) and the weight of the shank is then distributed onto the tip of the anchor. and will act as a ballast.
Without ballast, the weight repartition on the Océane tip is one of the heaviest of the market with 25% (18% for the CQR)
