Re: Mantus Anchor on Test

We do not have anchor cleats. We have mooring cleats but they are not designed to take the loads that an anchor can take, if we use them they take a basically stationary load of the yacht in a...

Re: Mantus Anchor on Test

Is you 3/8th chain a galvanised high tensile steel chain from China? Maybe the shank is a lever? And if its a good anchor, the fluke fixed? Are you, would you, use a Mantus anchor without...

Re: Mantus Anchor on Test

And I do not think Noelex has passed any educated comment on the bolts (and used the anchor without checking and has professed to knowing nothing about them) and to me those bolts seem quite...

Re: Mantus Anchor on Test

Bolts in this application, anchors, take all the load and the load is applied as a snatch load on a regular basis. I'm not sure that construction bolts are tested for repeated cyclic snatch loads -...

Re: Mantus Anchor on Test

I asked because mine, from 12 months ago, were mild steel and marked as such, below the minimum specification declared by Mantus at the time - so asking Mantus is not the answer. When queried Mantus...

Re: second hand rocna 20 - what would you pay

I have to ask: Why would a licensed dealer want to sell a perfectly good, regalvanised anchor, at less than half price?

Re: Mantus Anchor on Test

Hi Noelex,

Your bolts appear to be Metric (odd coming from America) HT bolts Class 8.8, 800 MPa. Normally they would be marked also 8.8, but marking standards vary. Imperial Class 5 bolts have...

Re: Photos of Anchors Setting.

I do not recall what my first 'underwater' was, but early generation of the type and rated to 3m, I used it as 'just under water' and it still leaked fairly quickly. Having learnt I treat the WG 1...

Re: Photos of Anchors Setting.

Taking pictures of anchors underwater is incredibly difficult, as your images demonstrate. And you do not really know how good they are till you download them - to discover there was some nuance you...

A well set anchor is one you cannot see, at all - its buried.

An anchor, apparently well set (still visible) does not mean it will hold when the wind picks up, a bit of a sea develops and...

Re: Best Anchor for my Sailboat

Celestial Sailor,

For the record: I own 2 Rocnas.

I had heard the Bulwagga was no longer in production, but that might simply have been someone trolling (a common problem I have heard). It...

Re: Best Anchor for my Sailboat

Noelex,

When you give the Excel the same complimentary treatment you are doing of the Mantus (you still have not looked at the bolts that hold it together) you might be qualified to comment. You...

Re: Best Anchor for my Sailboat

If you are into buying 'second hand' then I would not even think of a Rocna.

Rocna are not THE best, they are simply one of a bunch of good anchors but if you check posts on this forum you will...

Re: Best Anchor for my Sailboat

Good anchors are easily and readily available in Australia though they are seldom if ever all for sale in the same chandlery. We have easy access to Supreme, Boss, Rocna, Excel, SARCA, Ultra, Racer...

Re: Best Anchor for my Sailboat

I too have a 3kg copy danforth, I use it for my 10' dinghy. Its cheap and nasty. But we set it by hand, we do not sleep in the dinghy, and I would not use a bigger version (even if you paid me -...

Re: Best Anchor for my Sailboat

Sorry, I note you are based in Australia. Most people who post here are N Americans - My mistake, I simply overlooked your location.

Consequently very unlikely you were using a genuine Danforth,...

Re: Best Anchor for my Sailboat

Any of the more modern anchors will be satisfactory, Supreme, Excel, Kobra, Spade, Rocna, Fortress, SARCA. Sadly you will be restricted to Fortress, Supreme and Rocna. But you have a smaller yacht...

Re: Mantus Anchor "Resetting"

Very droll - but it was a completely serious question, are the 30mm short lengths of chain attached at or near the shackle for the shank. (Round here they use such chain as part of the assembly for...

Re: Mantus Anchor "Resetting"

Andrew,

Can you clarify - your 30mm chain links - you are attaching them to the chain at or near the shank?
