Manson supreme anchor

[chaika]

We're looking at getting a Manson Supreme for our SO 36i and are wondering whether the 20kg size will fit on our bow roller. I know it is a size bigger than the tables recommend for a 36ft boat, but that's what we want - if it will fit.

Does anyone else have a 20kg Manson on a 36i?

Check this thread: jeanneau.proboards.com/thread/2788/rocna-anchor-question

Sitara has a Rocna 15 on a 36i. Manaia has a 20 kg Manson Supreme on a 43DS.

I fitted a 16Kg Manson Supreme to my SO379. Although we have anchored only a few times, it seems to be the right size for the boat. It fits the bow roller perfectly.

We replaced a 45lb CQR with a 20kg Manson Supreme and it fits very well in the anchor rollers, the distance/angles in the shank/blade haven't caused any problems.
The tip of the blade is about 50mm from the hull when the anchor is stowed, but it is impossible for it to get any closer....

It looked massive in the shop, but once on the boat it seems just right (it's on the bottom doing its job at the moment, but is will try and take a pic when it comes up !)

The shank fits under the moulding in the anchor locker without problems and it self launches ok.

Aesthetically, the roll bar is visible, but we are used to it now and I like the performance too much to mind this !

Thanks Manaia, that's helpful info. We've been trying to estimate whether the tip will hit based on published dimensions, but it's not easy. I'll check with our local dealer to see if the bow roller on the DS43 is the same as on our 36i.

Hi Chaika,

I have a Manson Supreme 35lb on my SO36i and it fits fine on the roller. However, sometimes, when I pull it up, the tip of the anchor comes and hits the bow! It usually results in a bit of gel-coat flying off!
I have since added a small stainless steel plate on the bow and that fixed it.
The 45lb being bigger, I would be wary of using such an anchor in the original bow roller configuration. Even if it did fit, the damage it could do when pulling it up might not be worth it.

In my opinion, one would be better off adding a few meters of chain rather than getting a bigger anchor.
I have 30m of chain + 30m of rope... although in hindsight, I would have preferred 30m chain + 70 meters of rope, although where I normally anchor, this has never been an issue in the last 3 years...

All the best in your decision...

Allegria , slightly off topic , how do you manage to get from chain to rope on the chain gipsy ?
I'm also playing with the thought of reducing some chain weight by using about 10 meters chain and the rest dyneema rope , but the idea of having problems with the transition chain >>>>rope holds me back.

I know a protecting S/S plate around the bow gets the gelcoat save , but after awhile the S/S cover is also severely damaged no ?
I'm planning of making afairly thick blanket to cover the bow during anchoring .

Back on topic now , I would use a 16kg manson on a 36 foot, not more . I'm sure Manson also suggests that .

Hi Sailbleu,

Agree with your assessment on the anchor. A 16kg Manson and a good length of chain will do the the job well.

The trick with the chain to rope connection: You (or your chandlery) need to splice the rope to the last chain link. Then no problems with the gypsy.

Not sure I'd go with Dyneema though. Simply not enough stretch, so very little shock absorption when the boat jerks at the rode while swimming at anchor. I think you'd have a smoother ride (and less chance of dragging) if you stuck to 3-strand nylon. Easier to splice than Dyneema also.

I use a flat wrap around fender for the bow. I put pictures and details on a post last year discussing Delta Anchor

Hello Jon , I agree with the little stretch of dyneema rope , but on the other hand when using only chain there's surely no stretch either.
But the breaking strenght of nylon rope does not compete with chain or dyneema is it not.
In that case I think you weaken the chain of command (so to speak) enormously don't you agree.

But another thing, a rope doesn't work with a gipsy no ?
Do you run a loop around the gipsy (with the rope that is) ?Or do you use the drum ? And how do you switch to chain because of that loop or use of drum ? Does it go smoothly ? Never tried it before and I don't want to lose any fingers you see
Questions , questions and questions

A number of folks local in my area, use a combo chain/rope with a windlass. The trick is using a rode that is the correct diam for the gypsy.

Then yes, one needs a splice at the last chain link to the rode in order to make it work. Other ways of connecting will not go thru the gypsy. 3strand is easy to backsplice, a dynema cored line a bit harder. Then a new style out, which is about 8-12 strands called Mega Braid by New England ropes, but more of a wooven, stronger than 3 strand, not as much stretch, but will stay in a smaller volume than 3 strand or a wooven style seems to be taking some hold in some area's, altho the price is still up there. Mega braid will stretch 10% at 15%, 3 strand is 16% @15% breaking strength.

I have about 10 m of chain spliced to the end of my anchor rope, and the standard gypsy on my SO30i handles both rope and chain and even the splice with no problem.  The 3 strand nylon rope has some stretch as you would expect.  It was neatly spliced by the rigger who setup my mast originally.  I feel I should have done it myself, but there is some comfort in the professional job, and so much to do commissioning a new boat.  I have previously used a full chain on charter boats.  With 3 or more times depth, the weight of the chain and the catenary curve taken by the chain between bow and anchor in both theory and practice effectively softens the force take up, even though there is no effective stretch in the chain in normal anchoring.  With rope there is no real weight in water, so no catenary, and the stretch is necessary, though the length of chain at the anchor end provides some catenary effect as it is lifted off the bottom.

Sailbleu,

I have Nylon 3-strand 9/16" rope spliced to the last link of 50' 5/16" chain on my SO35. Splice was professionally done. This set up was recommended by my chandlery after they inspected the boat and gypsy. Seems to have worked fine during approximately 30 anchoring jobs over the each of the past 5 summers.

The gypsy has no problem transitioning from the chain to the rope. No need to take an extra wrap or move to the drum when pulling in the rope. However, it is important to keep tension on the rope on the inboard side of the gypsy. Otherwise, the rope will will clump up and foul in the gypsy guard. (I learned this the hard way - twice.) So when lifting the anchor, I must be on my knees at the windless with the control in one hand, while constantly keeping tension on the inboard end of the rope rode as it comes off the gypsy. Once it transitions from rope to chain, this is no longer necessary; I can then stand up and finish the retrieval process of the chain and anchor.

I do watch my fingers very carefully when tensioning the rope, however!

Thanks to everyone for their comments. Today we tried a 45lb Manson Supreme on the boat and it was definitely too big! While it fit on the roller (just) it looked like it would do a lot of damage on the way up, so we took it back to the chandler and exchanged it for a 35lb-er, which fits well and seems to behave more like our Delta when launching and retrieving. For now I'll just make sure I hold it off the bow with a boat hook as it comes up, but eventually we might opt for a steel plate.

Incidentally, we have 55m of chain spliced to 40m of nylon rope and we generally put out 5:1 scope or more - as much as we can given the available swinging room. We've dragged a few times with our 16 kg Delta and are hoping the Manson will give us much better holding power.

OK I am biased and have a vested interest as the designer but what about a FenderFlex? 

www.fenderflex.com you can get them in Australia via the dealer Bob Littler Agencies bla.com.au

Hi Chaika
I'm looking at a new generation anchor for my 36i - I've been told by Sitara that the Rocna fits the bow roller - is there any particular reason you chose a Manson over a Rocna?

We could see that there would not be much of a difference between the Manson Supreme 35 lb and the Rocna 16. The Manson was a bit cheaper so we chose it.

We recently used the new Manson in winds of high 20's knots with gusts into the 30's. In 2 different locations for 2 days/nights each, in sand, it held absolutely solidly (the chart plotter and our new laser range finder confirmed we didn't move a metre). However, in yet another location in thick weed, we couldn't get it to hold, but I wouldn't have expected the old Delta to hold either.

[Quiddle]

Thanks for that, like you I think they're much of a muchness so I will go for the Manson which is £40 cheaper.
