Mantus and Sarca anchors

I finally got to see The Mantus and Sarca anchors in the flesh or should I say metal at the Seattle boat show. I was more impressed with the Mantus display and spent some time talking to the designer of the unit. Now I understand better why there are users who are impressed. If I had a need for another anchor I would give it a try before going full throttle in favor of the anchor. Because there are now so many good anchors on the market I can see how it might be difficult to decide which is best. Owning more than a few of these good anchors also presents a problem in the logistics of which to use where to store and how to deploy. For small light units not such a big deal but on larger boats I think it best to have one good all around performer on the bow and other light units for back up or multiple anchor situations.

The Sarca Excel in alloy make a great spare anchor. The shank slides out the bottom, and the two pieces thus become very compact for storage. The forward part of the lower section is weighted. When using a chain rode the holding power is not significantly different to the galvanised version.

I do not know anything about the Mantus, and have never even seen one.

I do know about the SARCA Excel anchor, since I have one and have deployed it many times in a variety of conditions.

It is a Excelent anchor. It sets reliable, and has not drug that I can tell. Not much more to ask of an anchor, so I am a vary hasppy owner.

SARCA at the Seattle Boat Show

It seems Sarca is expanding its presence in USA. Were they represented by the Vancouver Island agents, or was Rex Francis there?
Sarca usually exhibits at the Sydney Boat Show, the stand is run by Rex and his wife, who I think live in Melbourne, 600km distant. It`s not a glitzy set up, but the anchors, and information, are all there.

Mantus seems to be a Rockna knock off. The difference is you can break down the Mantus for storage, but who does this. I have a 77lb Rockna and it stuck each and every time! OMG another anchor thread......

According to what I read in Practical Sailor, the Manta sets at 17 degrees while the setting angle on the Rocna or Manson is 32 degrees. They claim that the Manta MAY do better on hard bottoms covered with some soil - because they don't dig in as deep. In all other bottoms, it appears that a 32 degree setting angle allows the plow to dig in deeper and generally provides greater holding.

Interestingly, they also wrote this month about snubber chain hooks and how many can reduce the working load limits of chain by 25%. I have been using a plain old stainless hook and may have to rethink this.

I have used a Mantus for 3 years and have nothing but praise for it compared to the CQR it replaced. The first time I set it, I was backing down and it set so quick and firm that I thought the snubber was going to break. When retrieving the anchor, you generally have to power over it with short scope. When we sold our 38 foot trawler and moved up to the Nordic Tug, the anchor came with us. By all measurements, it is not big enough for the Nordic Tug (45 lbs) but the anchor roller won't fit anything bigger without substantial modification. Even undersized I still have confidence in the Mantus as it has held in a good bottom with winds up to 30 knots with a 4:1 scope of 1/4 inch HT chain. When I can build a pulpit to fit the 55 lb Mantus, I will probably upgrade and relegate the 45 lb to spare anchor status as I can break it down.

No claims on best or anything else. I bought the Mantus because they shipped a 45 lb anchor to Alaska for less than $5. That impressed me. The anchor has impressed me too.

Just looking at a bear claw hook bothered me. It looks to apply a concentrated load to one link. Mr Hinz didn`t think much of them either.
I have a "Sea- Dog" vertical groove plate which sits under a link. It has 2 line attachment points. I think it`s better, hopefully it does less to reduce rode strength.

On Steve's setting vids the Supreme (a scoop anchor not a plow) has'nt been bested for short scope performance. Perhaps the 32 degree "setting angle" has something to do w it. Gordon J what exactly are you refering to as "setting angle"? I have some ideas but ........

Mantus 85lb

Last spring we replaced our 66lb Bruce with an 85lb Mantus. We've been very pleased with the anchor and gear so far. Also use their bridle and swivel.

Nice company to deal with.

If my bow roller had been able to accommodate a roll bar I likely would have bought the Mantus. However, I have been exceptionally happy with my Sarca.

I believe the Manson Supreme was video taped on a short scope performance.

Setting angle is the measurement in degrees between three shank and the plow. Imagine the shank its parallel to the bottom. The shank is zero degrees. The Mantua digs in at 17 degrees the others at 32. In other words the Mantua takes a shallower bite if bottom.

Yup, the Sarca Excel. I should have been more specific.

Ford vs Chevy lives! The anchor debate should include a Mopar or two. Just for those who like hemis. Not to mention a Buick Wildcat.

Barrett Jackson "next door" is now over. Like anchoring success, the winners were those that had savvy owners who understand preparation. Much more to it than the badge on the tail.
