Rocna anchor

[Norca]

I don't think it would stay there for long in the St Lawrence gulf
I have had green water over the bow on a couple of occasions,
I have ordered a new mantus 25lbs for delicery in January, so I'm looking for a way to store it,
Maybe I will use a PVC pipe like Sumner for now, but if I could find a way to convert the stock bow-roller to a
pivoting roller I guess it could fit there.
I'll just have to wait until I get it on the boat and then come up with something.
I don't really want to drill holes in the deck to install a new, longer roller if I can avaoid it.

In the spring I am planning to try this: http://mantusanchors.com/mantus-anchor-mate/.

I spoke to Greg at Mantus through the Mantus Anchors facebook page. Good customer service,even though he couldn't help but to make fun of the 26X bow roller a bit. SIZE DOESN'T COUNT, right? He wasn't sure if it would fit on the small 26X stock roller, but asked me to try it and if it didn't fit Mantus would give me a full refund and pay the return shipping. He'd probably do the same for someone with a 26M.

I wanted to get a new generation anchor and was looking at the Rocna. I recently bought instead a 13lb galvanized Mantus for $120 cdn...like 30 cents US but I haven't tried it yet. We don't do a ton of anchoring out, and when we do it is always in fresh water with a good forecast, so I felt the 13 lb would met our needs. I just wanted something that would set quickly in sand or mud and would reset during the night as the breeze shifts around. The boat came with a small danforth knock-off that fits in the anchor locker with 200' of rope and about 6' of chain. That anchor never dragged but we never exposed it to anything more than 20 knots or so.

I know it would be nice to have a 22 lb monster up on the bow, and I would do that for ocean anchoring or any time that I didn't have a dock available for the night, but where we sail, for now, I am never more than 5 miles or so away from a Marina. Our principle anchor use is to hold the boat while we build sandcastles at a beach, or if the weather forecast is calm, then we'll anchor out for a night or two.

I have a Mantus 25# anchor literally sitting under the Christma tree. $US exchange is brutal.
Hope it fits on the roller of my Won't know until April when I retrieve mine from storage.

I switched over to the Bruce style like in the pic. Have had great performance with it!!!!! I do anchor in mud mostly.

================================================================================================



I use the 25 lb. Manson every night now and the 22 lb. Bruce style claw as the second anchor down when needed but we started with the claw and it never let us down regardless of the bottom. I really liked it for the rocky bottoms in Idaho and Canada. I feel it is stronger in those conditions were it is hooked to a rock and the loads on it are more concentrated vs. in mud. I think the Manson would be just as strong in those situations and will outperform the claw in mud and sand but if you are limited on funds I'd get the 22 lb. claw from Defender (see link in other post above) for under $80. That is a good deal.

I can't see going with anything less than the 22 lb. claw. With your boat and crew at possible risk $80 is just not that much to spend for some peace of mind. In fact if things to to he** $265 for the Manson will seem mighty cheap. I also have a Fortress FX-11 on board but have never used it yet, but have it just in case I lost one of the other anchors.

Remember when you look at the anchor sizing charts the boat lengths and anchor sizes are usually what is recommended for normal anchoring situations and not that night you have to sit on anchor in 40-50 mph winds which can happen. It also isn't just boat length that is the important factor but also the windage so even though the S and D are 26 feet the X and M, also at 26 feet, will put more stress on your anchor gear with their higher freeboard. The weight of the anchor isn't what secures the boat but the surface area and the shape of it that is dug into the bottom that keeps you secure. An anchor that weighs more is going to have more surface area in the bottom. The added weight also helps keep it on/in the bottom. Also the more chain you have the better as the chain will want to lay on the bottom and that keeps the pull on the anchor more parallel with the bottom which helps to pull the anchor into the bottom vs. up and out of the bottom. More Scope helps in the same way

Scope is the ratio of the length of deployed anchor rode to the height of the bow chock above the seabed. The greater the scope the more horizontal the pull on the anchor, and the better it will hold.... http://www.boatus.com/boattech/casey/an ... -rodes.asp

As BoatUS says (http://www.boatus.com/boattech/articles/anchoring.asp):

With so much investment literally riding on your anchor, your boat's ground tackle system is no place to cut corners.

I decided on the Mantus after reading the "Photos of Anchors Setting" thread on cruisersforum.
All 2142 posts of it
There are a lot of good information there for anyone who cares about anchoring safely.
I have a 9kg ( 19,8lbs) Kobra plow anchor, and it seems to be doing good in most of the pictures, but it tend to do as the name implies: plow when the load is high in winds over
say 20-25 knot, what is important is not only holding, but also how the anchor behave when the wind or current turnes the boat around, and it must also set fast and not drag too far because it could pick up debris, foul and then not set properly
In the thread the Mantus, Rocna and Manson seem to be the best allround with good setting and they can turn 180deg without coming loose. These anchors don't plow, they just dig deeper as the load increase

After about 10 years without dragging, I finally dragged this summer while anchored in Cuttyhunk in very soft mud and grass. I stayed put nicely during 20 hrs of 20-25 mph wind. I felt comfortable going to shore for a hike. When we returned after 2 hrs, Vrijheid was tied to my neighbor's Pearson 36. Vrijheid started dragging minutes after we left. (Perhaps she felt abandonment and threw a fit.... Quite a scare. We were very happy with the good Samaritan in the next boat. Next time I will use my FX16 in these conditions. Lesson learned.

What is holding that anchor in place??
I can't see no ropes, no bolts or anything holding it in place.

Nothing is holding it besides gravity. I suppose if we were in rough seas a bungee or something might be a good idea. Although it's never moved up there.
The photo is deceiving. The chain goes right down the locker and the shackle sticks out on top of the locker. It's never gone anywhere. If it slides forward the chain pulls it back.
I wouldn't trailer with it unsecured.


--Russ

During trailering I secure the anchor and bow with a ratchet strap under the cleats, over the anchor shank and than around the trailer beam. Boat and anchor are well secured this way.

Interesting note on anchors I am currently on the boat anchored on a grass flat with 25 knot winds. On a three pound danforth and sixty feet of 1/4 three strand. Hasn't budged in two days.
My 50 lb main anchor is just steadying the bow.

Lots of chain on you anchor

Set it at long scope, then reel it in. I've never figured out why so many books say set it at short scope, then let out.

The enemy in Cittyhunk is eel grass. If you get a nice ball in your anchor it will feel set but drag once it blows. Once you dig into that mud, most anything will hold.

Anchor threads are like oil change threads on auto Fora, they get brutal and bring out all the fluke cakes.

Letting out too much scope initially can cause it to stack or coil up on itself and foul the anchor, has always been my understanding. See too many people just throw their anchor overboard and let it free fall. You anchor hits the bottom and the chain just piles up on top of it. A lot of times with fluke anchors the chain sinks faster than the anchor and your anchor can end up on top of your rode. Might not be a huge problem in shallow waters but have seen people repeat this process several times at deep fishing spots only to have it foul most times. That would be my guess as to the recommendations. Slowly letting out line and making sure your anchor hits bottom first and the chain laid out behind it.

I have had green water over the bow on a couple of occasions,
I have ordered a new mantus 25lbs for delicery in January, so I'm looking for a way to store it,

I take the anchor off the roller and strap it to the deck when I know its going to be steep and the bow digging under waves. Without a hoop on the roller its just flip it up on top the locker and strap it down till the next destination. 90% of the time it just rides on the roller though. The mantus has a long pointed scoop so it does hang a lot further off the front than other anchors.



I was pleased enough with the 25lb mantus on the mac I bought a 35lb for the cat. I still have the 25lb mantus if someone is interested send me a PM.

I'd relieve you of your Mantus but shipping on top of a fair price would put it back up into new anchor territory. Besides, I'm kind of interested in Rocna's new hoop-less spade-type Vulcan anchor. Another 'some day' item.
