Picking an Anchor - Rocna Vs Manson

I have done quite a bit of research on this and ultimately decided on the Manson Supreme anchor. Trouble is, we kind of need it and it is not in stock through Fisheries. We are ordering through Fisheries due to us needing to put it on the barge to Juneau.
My question is, is there enough difference between the Rocna and the Manson Supreme that we should wait for the Manson?
Would appreciate any input.

The Rocna fisherman version is a closer comparison if you are planning to use the slotted rode connection. Other wise, they are both great designs and work well for many owners including myself with a Rocna original. Factor in the cost and availability and just grab one and use it. Some have complained about galvanizing issues but unless you think your anchor should be sparkle pretty forever, you could ignore that banter.

I got what we have because it was on the shelf in front of me at a reasonable price and that made my choice between the two.

I can not speak for the Rocna but I do have the Manson Supreme. Best anchor I have ever used. If you can wait for a MS to arrive, you will not be disappointed.

Many of the larger cruising boats are going with the Ronca--probably as many or more than Manson Supreme. As Greg noted, if the slot is important, then either the Ronca Fisherman, or the Manson Supreme.

As far as holding and durability, they are going to be basically the same.
 
The slot will allow you to reverse the pull on the anchor, and get it out if caught under a log, cable or rock. I am not certain about the current Manson Supreme, but my Boss, (Manson) has a bolt which will lock the chain shackle in the back position of the shank, or the forward over the crown/flukes.

The same thing can be achieved by putting the anchor chain thru a hole in the shank near the crown, over the flukes, and then using some break away system near the top of the shank. If the anchor is stuck then you can break the ties, and pull form the area over the fluke, in the reverse direction.

They generally do not recommend using the slotted connection for long term or overnight use because it can release when the pull changes direction with current flow or wind. So you would us it to hold a position (fishing) while you are actively on watch so that you could manage a reset easier. A fisherperson might set an anchor a dozen times or more in a day of fishing and all those sets means a greater chance of fouling so having a retrieval option is great. Bob is talking about how to rig a non-slotted anchor to effectively offer the same option. If you want the unit for overnighting and not fishing use, you would likely just use the hole and not the slot anyway.

For me, any anchor that puts me into using a slot will stay on the shelf
An anchor is to make the boat stay where it's put. That feature could easily unseat your anchor while you're ashore and there are many ways to unstick a stuck anchor without the chance of every time you set this type, it may come un done, it's just not sea worthy for overnight or while away
 
George, the feature of the anchor is nice to have, if you know that you are going to be in an area where there are rocks, or other obstructions which may hang up the anchor. But it is not for overnight use, if you are not willing to stand an anchor watch. When you use the fixed hole in the Supreme or the bolt captive position with the Boss, it is just as solid and safe as any other anchor. I would only use the slotted position, if I were going to use a trip line and buoy. Another option, is t fix the main rode, to the fixed position, and have a second shackle with a short floating line, to the secondary slot. If you hang, up, you then can use the boat to break out the anchor with the secondary line in the slot (normally loose, yet not subject to the issues of a trip line (someone mistaking it for a mooring buoy, getting tangled in a prop, etc. , and then winch it up as your normal would.
 
Thanks again for all of the helpful info. We can see now the difference and will wait for a slotted anchor. It makes sense for us with our need to anchor while fishing.

.....have a second shackle with a short floating line....

thataway, could you explain a bit more how this works. Why a floating line? Does this line come all the way to the surface? Does it sort of "stay" near the rode somehow?

I nearly had to cut the anchor loose a couple of months ago when the anchor got hung up in rocks. I'm looking to implement an emergency retrieval system for my Bruce anchor.
 
I carry various types and lengths of floating lines. For this use I would probably use a 3 strand or solid braid Polypropylene at least the depth of the water at high tide plus 10 feet. I would use couple of electrical ties to hold it to the main anchor rode near its top. Floating line to keep it from snagging on some object on the bottom (because if the anchor is fouled there is a chance that the chain is fouled.) I don't tend to leave floating lines loose, because then they become an object to foul someone's prop, or rudder.

Other places for floating lines: the crab and shrimp pots is one. I also use them for shore tie lines--such as anchoring off, and then a stern line to the shore. For Polypropylene (single braid solid or 3 strand, the SWL is about the same as nylon. Poly line is has less stretch than nylon--and desirable for working out an anchor.
 
Ordering our new Manson anchor today from Fisheries as they just got them in. I wanted to say thanks again for the helpful info.
We won't have it in time for Elfin Cove this weekend but hopefully for the next outing.
