Read a test conducted by some national boat equipment magazine. They used a BIG tow boat and tested several types and brands of anchors. It was VERY well done which is why I chose a Rocna. If you want to go cheaper and have almost as good an anchor, the Manson looks pretty good too. Same design. On Thu, Jun 9, 2016 at 4:19 PM, John Schinnerer <john@eco-living.net> wrote:
Thanks Larry - the 10 lb. model I assume? That's what brackets an M17 in their sizing chart. Though their chart goes on boat length only; Rocna tables go by both boat length and displacement, which seems a bit more logical to me.
And of course each maker claims everyone else is over-rating and they're not... :-p
cheers, John S.

John,
I've been using a Manson Supreme in the San Juan and Gulf Islands for several years now with very good results. The Manson is very similar to the Rocna.

Thanks Keith for the further info.
Good to hear you are choosing options based on others' positive real world experiences. It can be hard to cut through all the self-promotion by designers/makers of these devices!
I have been looking at the Rocna info among others and yeah, the Rocna 4 is probably adequate for an M17, and the 6 looks like solid secure overkill as a primary anchor.
Keep us posted on how it works for you. The types of anchorages where I would most need something are up your way (San Juans, & Canadian islands north of there).
cheers, John S.

Most of the anchors I have used are either danforth's on smaller boats or
Bruce's or some similar knock off on larger vessels (large for me is 27 to 36 ft)
In the case of danforth's in more exposed & rocky anchorages up here they just don't seem to reset well..
The Bruce's are popular up here but my limited experience with them is you seem to need to select them in biggie size to get the job done, invariably it just seems like a lot of anchor to manhandle.
A number of guys at my Marina have had really good experience switching to these new scoop type anchors (Rocna, Manson etc) that have performed well for them in a wide range of environments, including rocky anchorages..
So when a Rocna 6 (13.2lbs) came up for sale on Craigslist for $175 Cdn, I snapped it up... Based on the Rocna sizing guide this should be more than plenty even for a heavier exploration rigged M17 like mine..
So I guess time will tell.. I am dying to get out and try it..

Absolutely...I was just addressing sizing considerations and not bottom
types vs. anchor types.
What does work well in rocky/reefy bottoms? And can be retrieved from same? Ideally I suppose one wants to avoid anchoring in those kinds of places but sometimes it's unavoidable...
Curious why you chose the Rocna. I've been looking at those among others. Spendy...but worth it? Or just pricey 'cause they're patented?
cheers, John S.

I also think Connie hit the nail on the head (as he often does) when he
points to different environments needing different anchor set ups...
Certainly the wind and waves are a big part but also the type of sea or lakebed bottom.. My danforth works really well in a sandy or mud bottom, but a lot less so in rocky conditions. It doesn't set as reliably and it certainly doesn't reset very well on it's own in a rocky bottom.. On Jun 6, 2016 10:26 PM, "John Schinnerer" <john@eco-living.net> wrote:
