New Anchor

We have a Tartan 33 with a old claw anchor. We sail mostly in southern Florida (Gulf coast and time to time the Keys when we have vacations). Since we spend each week end at an anchorage, I am decided to invest a bit and sleep better at night

First thing, i am planning is to have more chain than i have today. Since we mostly anchor in 6 to 10 feet of water, i was thinking about 50 feet of chain. Will make the removal harder but i think it will help with the holding.

Then come the hard decision of the anchor type and size.

Most of the anchorage we go are sand and mud. I was thinking about a Manson Surpreme 25 or 35 lb. (not sure if oversizing a bit make a huge difference).

I am interested by all ideas or advice before investing.

Thx you

Re: New Anchor

My 60lb Manson Supreme will not set in compacted sand and weed.
I would look at Mantus or Rocna.

Re: New Anchor

Hi I have a fisher 32, high freeboard with pilot house so high windage. I tried a Rocna, found that it was not entirely reliable so sold it and bought a Sarca Excell #5, a much better and reliable product in my experience.

Re: New Anchor

I previously had a Mason Supreme. I switched to a mantus and could not be more happy it sets much better in grass. But either choice will be much better than what you currently have

I have had a Sarca on my previous Mono and was pretty happy with it.

Re: New Anchor

We have an old claw anchor here too. An original Bruce 33 pounder. I would only buy a new anchor if I lost this one. Then maybe I would look at the newer designs too. Why not. Sure.



What claw anchor do you have now? Has it ever failed you?


50 ft chain is not alot. We have 8mm chain, 100ft. No winch. Boat 26', 3t.



Cheers,

b.

Not our experience with our 60 lb Manson. In use for about 13 years now, and we live at anchor pretty much full time, and have anchored in most bottom types. Only places we have had setting problems have been thin sand over rock, or where we were fouled in trash on the bottom (lets see... a pair of board shorts, old netting, a crab trap, and yes, a kitchen sink!).

Locations have ranged from Tasmania up the east coast of Oz to Lizard Island, New Caledonia, Vanuatu and various offshore reef systems. We use all chain, 10 mm short link.

The anchor was coming with the boat. Probably the original from 1981...Only for that reason i think it makes sense to replace it. Anchors are much better today.

I calculated 50 ft of chain since water here are shallow and we usually end up anchoring with 6 or 7 ft of water. I have at the moment 25 ft.

I dragged once seriously with wind over 25 kts on a mud button. One other type i dragged but the anchor reset itself.

My first instinct was to go for a Fortress that seems to have great review for mud and sand. However the Mantus, Rocna or Manson may be more versatile and more adapted for my program.

Re: New Anchor

I would check out Spade anchors. but then again I am biased, as I have used one:-)
To me they are worth the extra money.

Re: New Anchor

All good advice and good equipment. We are happy with our 121# Rocna on 320 feet of 7/16 chain. We are 58 feet, 40 tons.

We dragged at the end of each swing in hurricane Hermine, Newport, RI in mucky goop. We stopped the drag by hand steering using the storm induced water flow to reduce swing from +/- 45 to 15 degrees.

Rocna has been solid for us throughout the Caribbean

Re: New Anchor

Here is a interesting Video on modifying the Manson Supreme.
I will definately modify the tip of my Manson. The small fins on the pointy end of the anchor stop the tip from contacting packed sand and the anchor just keeps sliding. I have watched it!

Fortress (=Guardian, if you can do without hard anodizing to save some $$) is a great anchor but it is quite big and difficult to stow on the bow. It makes a great second anchor to deploy from the dinghy.

I also know that some Fortress / danforth style / anchors refuse to re-set when veered.

If you are into Mantus / Rocna style then check our Spade and Bugel anchors too. Both are known to deliver great service.

I have seen a Rocna with shaft bent. This problem is said to be solved by Rocna company (China). Still, some chandleries stock up and you want to avoid to be sold such old stock.

Cheers,
b.

Re: New Anchor

We sailed around the world with a Manson Supreme and loved it. The only bottom it would not work on was boulders. I suspect that only a big fisherman would have worked there. On the other hand, I noticed that Rocnas are noticeably cheaper than Supremes (looking for anchor for a new boat). I think they functionally very similar, I would have no concerns about going with a Rocna. I am sure other, similar anchors like SARCA and spade are also good.

Edit: i would go with the manufacturer's recommended sizes. No need to go heavier in my opinion.
