No problem at all with it setting.

Also we haven't had a problem with it landing upside down and needing it to roll upright.

Love the anchor.

Re: Mantus anchors

Unfortunately, frequently manufacturers' recommended anchor weights are heavily influenced by marketing rather than reality.

Consumers assume a manufacturer who recommends a small model for a specific sized boat must have a better design than a manufacturer who is more realistic. Thus there is a strong temptation for manufacturers to specify small anchors, particularly when it also makes the the anchor more appealing to boat manufacturers. A small original equipment anchor means savings can be made with the anchor winch etc.

Thus we have the situation where anchors like the 25 kg Delta are recommended for boats from 53-63 feet.

For a cruising boat the biggest anchor you can fit and reliably manage is not bad advice, and this philosophy works for any design.

Re: Mantus anchors

'Just saying in my prior post, that several manufacturers offer new generation anchors that work fine without the big roll bar. Spade, Rocna, Ultra etc. I personally dove on our anchor nearly every day last summer, and never once saw it lying on its side or upside down... so why buy an anchor today that's massive in size when compared to the others, plus one would also need to somehow accommodate an enormous hoop on the bow just to get the thing to work properly.

Well, the bottom line is.... it's your money, buy whatever you want. But don't expect to be breaking a 175 pound anchor down when underway and storing it in a locker.... 'not going to happen.

Re: Mantus anchors

The Oysers I have sailed on had open style bow fittings. Why will a roll-bar be an issue then?

I know boats with bowpit / bowspirt slots can't take the roll bars in. But why can't Oysters?

Re: Mantus anchors

It's not a question if the Mantus will fit on an Oyster, but rather if a much smaller, lighter and more compact model will do the job just as well. I've seen the 170 pound Mantus at the Annapolis Boat show, they are massive in size compared to other makes of the same weight. Why would anyone want something the size of a 55 gallon drum hanging off the bow of their boat?

I'm just suggesting the OP look at the actual anchor being considered prior to purchase instead of reading reviews and google searching. Personally, I don't care what he buys and I'm sure the Mantus will do a good job, BUT... I know he's going to be shocked when he takes delivery of the thing and sees it mounted on the bow of his nearly 2 million dollar yacht.


Actually, I doubt whether the 170 pound Mantus will fit on the bow of the Oyster. Due to the much larger size of the anchor, it's likely the anchor tip will come in contact with the fiberglass bow of the boat when pulled in tight. The OP should first request a profile cutout of the anchor from the manufacturer to see if it will fit. Ultra, provided a profile of our anchor prior to purchase for fitting purposes. I'm sure Mantus can do the same.

Yes. Good point.

Perhaps because a large anchor may have more holding power. Holding power may be fluke-area related. Hence a big anchor.

I am 100% with you on all your comments and especially where you say about the tip of the bigger anchor possibly getting in contact with the bow and marring the gelcoat there. Seen this happen on more than one boat.

However, I'm hard pressed to see much of a difference between the Rocna and the Spade, or the Sarca and the Delta...

And, based on what's laying around in consignment shops like Bacon's or Sailor's Exchange on the US East coast, Deltas can be had for pennies on the dollar, relatively speaking... Appears to me lots of folks have traded up from Deltas to Rocnas or similar, I'm just not seeing them switching back to Sarcas... At least here in the States, where I have yet to see a single one...

Of course, perhaps there's something distinctive about the Vulcan and the Excel that I'm just not seeing from the pics...
In the flesh the Sarca Excel is nothing like a Delta nor does it act like a Delta.

Re: Mantus anchors

A 60', 60,000 lbs displacement boat would do fine with a 125 lbs mantus in any condition. I would only go to the larger anchor if I were going to high latitudes and wanted an extra margin of safety.

I'm of the school where if people are not pointing at your anchor and laughing then it is too small. But that is just me. I'm using an 85 lbs mantus on my 50', 32,000 pound boat. I'll switch up to a 105 when I take off for a few years cruise.

I also tell people that my boat is a working boat not a work of art. Of course it is a Gulfstar and not an Oyster.

That the mantus breaks down, and you can carry replacement parts (spares), and setting the first time are very important to me.

The 125 pound mantus comes in stainless too. they are works of art and quite pleasing to look at.

Disclaimer: I started as a mantus customer, now I am a distributor. I've owned a Rocna, and a Manson (and a delta and who knows what else) but think that the mantus sets faster and deeper.

Certainly, if one really has a problem accommodating the roll hoop, there are other good options out there...

There is at least one potential upside to the roll hoop, however... When cruising in waters clear enough to see your hook resting on the bottom, if your roll bar is painted with a high-visibility color, it can serve as an excellent 'gauge' as to the quality or depth of your set, when viewed from the water surface...

That won't help much. We have a Rocna and are anchored in crystal clear water. It is either buried so you cannot see the anchor except the top of the rollbar, or you can see the anchor itself and the set is either not deep or not good.

It pretty much is always a binary thing with ours - paint wouldn't help much.

I like this - what color works well under water? (probably will void the warranty)

Excellent performance, strong.... and good looks.

I thought I made it clear that I see little significant distinction between the Delta and the Excel, based solely on the photographs I've seen... And, I've conceded there may be some major difference between the 2 that I'm missing...

And, judging from the pics I've posted above, I'm guessing there might be a few others who might have a similar impression...

I'm sure the Excel is a very fine anchor, and no doubt an improvement over the Delta... it's simply that - to my eye - the basic designs appear to be share more than just a bit of similarity...
