Re: Modern Day Anchors

Kettlewell,

Interesting prices.

I suspect that if you are a boatbuilder (they are a dying breed in Oz) or an importer (of yachts) then if you are buying a few then the prices of the Delta are...

Re: Modern Day Anchors

I do not recall which yacht but one of the Vendee Globe yachts was sponsored by a French naval contractor - all high tech stuff. They put a lot of effort and resource into it and came up with a...

Re: Modern Day Anchors

I was simply trying to balance Cotemar's assertions. If my comment is invalid, then so is Cotemar's - and no-one objected to his suggestions (made a number of times).

Here I see only an...

Re: Modern Day Anchors

Gary,

Was yours that lovely Salthouse at Nelson Bay! Down on the end of one of the arms before the fuel dock. Nice yacht, no wonder you wanted a performance anchor! If its the same, where do...

Re: Modern Day Anchors

Sorry Visarend, I was not ignoring you, but Oz went to bed, the thread has a 24hr life and your question became buried.

Our cat is 6t cruising weight, with an average for water and fuel (we seldom...

Re: Modern Day Anchors

Cotemar,

The Rocna and Supreme are both sold internationally and together achieve about 30% of the poll. This presumably covers sales, largely in the English speaking world (because the poll is...

Re: Modern Day Anchors

There is no answer, in one anchor.

We carry 3 anchors when we stray outside our comfort zone, once a year for a 3-5 month cruise. But in making our choice we accept we still compromise. We would...

Re: Modern Day Anchors

Sorry Noelex, I am overly guilty of simplification:(.

But the metal does not matter, the tensile strength does. A 250 MPa steel has the same strength as a 250 MPa alloy (and marine grade alloys...

Re: Modern Day Anchors

Depends where and when your anchor was bought as to whether its a genuine NZ model. The 55kg Chinese and 55kg NZ models look identical (fabricated flukes, both). Once ties were cut with the NZ...

Re: Modern Day Anchors

The Supreme shank is, min 800 MPa (but I think the quote is hyperbole, and wrong). They historically quoted Bis 80 and more recently quote min 800 MPa. My knowledge suggests its impossible to gal...

Re: Modern Day Anchors

We should not be anchoring in coral - damage should therefore be minimal

We have anchors specifically designed for retrieval from rock, the slotted, SARCA, Boss and Supreme.

Bad luck plays a...

Re: Modern Day Anchors

If you simply list the anchors that bend or tear (and read you post a bit later, when you endorse a genuine Bruce) then the suspect anchors are:

Spade, alloy and gal
Fortress
Danforth (I assume...

Re: Modern Day Anchors

The steel used in the shanks of anchors is chosen by the specifier. If he chooses 250 MPa steel500 MPa steel or 800 MPa steel - then he should get what he asks for, its easy to check. As you say...

Re: Modern Day Anchors

Nick,

I cannot argue.

I swap my anchors depending on what I'm doing. If I'm sailing round Tasmania I use an Excel as my primary (the one on the bow roller) and I have Fortress and/or Spade as...

Re: Modern Day Anchors

Alloy as a primary is fine in that most people, most of the time, do not 'suffer' under winds more than, say 25 knots, and as long as you have some back up in case the conditions are much worse than...

Re: Modern Day Anchors

Anyone who thinks alloy, or stainless, can ever compete with high tensile steel needs their head examined. Alloy has its place and as long as you are conscious of its limitations there should not be...

Re: Modern Day Anchors

Chuck Hawley posted some months ago (I think CF but do not recall which thread) that he had a Stainless Steel version on his yacht and he would post his experiences. Chuck has an obvious interest in...

Re: Modern Day Anchors

Useful and interesting advise. Probably works for other anchors as well. It is certainly the answer to anchoring in thin mud, be too aggressive and anchors simply swim. Better to 'worry' them,...

Re: Modern Day Anchors

Noelex,

We have tested a steel and alloy version of the Spade 80, so 16kg and 8kg. Frankly cannot tell the difference, except for the weight. They both set in the same distance, they both turn,...

I went through my Cruiser Forum archives and found this one posted in 1954:
