Anchor choices

I new to this forum and looking for some advice.
My boat is a Grabd Banks 42 2003. I have a 30 KG Bruce anchor which is good if the bottom is right but drags over hard ground and weed.
Im thinking of changing to a Rocna 40 KG, does anyone know if it will fit into a GB 42 bow roller system?
I appreciate any advice you can give me
Brian

Have you considered the fisherman's anchor for hard ground and weed?

Brian, it's been a while since I visited the Rocna website. If I recall, Rocna gives the dimensions of their various sized anchors. One could then "mock up" an anchor on paper and see if it fits on their particular sprit and roller system. They also have testimonials from customers. However, keep in mind that GB used different sprit and roller configurations from time to time. You'll have to make sure that your system is the same as others, etc. For example, I have a double roller and a friend has a single... Good luck! Welcome to our forums!

The first photo is my GB42 and the second photo is a GB46 with a Rocna 40. The space in front of the slot in the bowsprit is similar (or the same) in both the GB42 and the GB46. Yours may vary.

Edit: I don't remember where I captured the second photo of the GB46. It may be from the Rocna website, www.rocna.com.

No one anchor will do.

Different bottoms require different Styles.

The CQR , plow buries , good in weeds grass
The Danforth or Bruce dig in but seldom bury (unless the mud is really soft).

No one anchor can do it all, UNLESS its at least 10 lbs per foot of vessel , when a fisherman or Herrishoff will do fine.

Anchor Choices

Hi and thanks to those who offered advice and very useful pictures.
It looks to me that the Rocna 40 fits the GB 42 roller system. This forum seems to be a wealth of experience.
Thanks Brian, No Ice

FYI on my Grand Banks 46' I have a 45# CQR and a 60# Manson Supreme and they fit fine. The Manson is on the "self launching" roller set.

There's no downside for the Manson Supreme except for being good at bringing up mud. All roll bar types share that fault but no other roll bar anchor does everything else near perfectly except perhaps the SARCA if you can get your hands on one. If you like to work your anchor on the bow that should'nt be an issue. Most any anchor holds well but being able to perform very well in a very wide range of conditions is IMO most important.

I've used the Manson Supreme anchor for two years and have anchored up and down the east coast from CT to FL. It's the best anchor I've ever used and my CQR hasn't even gotten wet since I bought the Manson. I'd estimate that I have anchored at least 100 times, perhaps more.

The Manson Supreme is much like the Rocna. Awhile back, Rocna experienced some issues with the quality of the steel used to make the anchor. I'm,sure others on this forum will know more about that. That's the main reason I bought the Manson as I was unsure if the steel issue was resolved. The Manson is also a bit less expensive.

I have not regretted my choice. Hope this helps with your decision as confidence in your anchor results in a good night's sleep.

Have an original Bruce on my boat. For The mix of bottoms here in So California my Bruce is my main. I have a West Marine Performance (Danforth style) and a Second But one size smaller original Bruce as back ups.

Thumbs up

jclays,
How does that WM Performance anchor work? That's a Danforth type right?

Sorry FF, but you are just flat out wrong there. That is just your experience. You have no experience with the more modern multipurpose anchors, so you really should be a bit more circumspect before just dismissing the fact that there are anchors now out there that are suitable for virtually every bottom. However, only members who have owned and used these are really able to confirm it. Let's hear from any of the owners of these new generation anchors if they would ever go back to one of the anchors you continue to tout. I'm waiting…. ok, the anchor scene has been bit dull lately, and he asked for it…

Looking at the posted photo it would seem to have about half the burring surface area of a WWII Danforth.

LESS surface for better anchoring in a blow , Hard to believe!

The secret is how fast and how deep she digs in FF. Has to be seen to be believed. I sent you a DVD showing it - you chose not to believe...

I don't think there's much true argument that a fully dug in Danforth/Fortress style anchor leads in ultimate holding power in some bottom types...I can't prove or disprove this...just the results of every respectable anchoring test I've read. Hard to argue fluke surface with reasonable dig profile just as FF suggests.

and I would own one if I was a long range cruiser and thought I might be somewhere hit by a hurricane/typhoon...

....but I don't have a Danforth on board except a tiny dingy anchor because in my experience...getting one to set or temporarily hold when you really need it is a crapshoot.

So while I agree new gen anchors might have incorporated most of the good points and lessened the bad points of former anchors...I don't think they have the best or worst of any anchor and are great as a primary anchor for all around use.

I know NONE of the new gen anchors are a suitable "wreck" anchor (well they are - ONCE)..and there are specifically designed "wreck" anchors....so I think if you buy an "old style" anchor that IS best for every bottom type and situation...you would be in a camp that I know of only one other TF member resides in...

The West Marine performance anchor (Danforth type) works well. I just prefer the original Bruce. sets fast and holds great. The marinas by me have plenty commercial, and serious fishing boats. The majority use a Bruce or Bruce copy anchor. I believe anchors are a matter of choice and experience. What lets you sleep at night?
Cheers
Jim
