Second anchor options

A question for those familiar with Queensland waters. My Krogen 48' has a 55kg Rocna anchor with 300' of 1/2" chain. I have never dragged it. I also have 300' of 7/8" rope rode for a spare anchor, which I don't have.

If you were planning a trip to the Whitsundays what do you guys suggest for a spare anchor?

It pretty simple, what is the bottom commonly made of there?

Once you answer that you'll know what type of anchor to get.

How will you carry this anchor? Will it be hanging on the bow next to your Rocna or stored down below?

Do you have some chain to go with your rope rode?

The only weakness that scoop type anchors like Rocna have is in soft mud. You might want to consider a Fortress for that type of bottom.

Oh yeah, just for the record, your anchor is too small, it's the wrong kind, and you don't have enough chain.

Thanks for your reply, I would like to carry the spare in the rope locker, obviously I will have to add some more chain. There will be all sorts of bottoms from beautiful sand to rock and coral.

Yes, I know my existing anchor is a little small:-)

A large Fortress is a good choice, and it is easily stowed.

Brian, Hopcar was just yanking your chain, so pay him no mind, as they say.
I think your Rocna is quite heavy enough.

As to your query, I have been to the Whitsundays, but not personally cruised there bareboating, that is still on my bucket list. Our current boat has been up there with previous owners, but we just don't have that sort of time. My holiday would be spent just getting up there and back. But yes, I except the bottom would vary from sand through to coral, with some mud off river mouths only. Your Rocna would do fine for virtually all of that. The only one which might be a bit more versatile, especially over coral and rocks, would be our Aussie designed and made Super Sarca, (sand & rock combination anchor), with the tripping slot. However, I must admit bias, because I've got one. For my back-up, I have a large Danforth, with a mixed chain and rope rode, which has never seen the light of day out of the lazaret, so the advice re a Fortress or Danforth type second anchor is probably quite reasonable.

However, up there, something that won't damage coral, and can be retrieved easily if it snags in coral or rock could have the edge. I doubt you will encounter soft mud up in the Whitsundays. Seriously, I think your Rocna would be fine virtually everywhere, but set a trip-line with float if near rock or coral. Actually better still, where there is coral, I believe they like folk to use moorings placed there to save coral damage, so grab one of those if at all possible.

Brian, the Rocna (broadly speaking)is a spade type, is it not? We Sarca users, in a knee jerk moment, will claim our anchors superior to Rocna, but really, I don`t doubt the Rocna is good (especially if improved with a recovery slot). Our back up is a CQR, because that`s what the Sarca replaced, but a traditional Danforth/Fortress sounds good advice.
The Masters 34/Aquarius I owned had the shape of a Danforth moulded into the fibreglass foredeck to retain one, Clem Masters knew a thing or two about designing boats.

Peter, Yanking his chain, in an anchor thread! Would I do that?
Seriously a modern scoop anchor, like the Rocna and a Danforth style like the Fortress is about the best you can do.

A second anchor should address the possible need for a replacement of the primary if something should happen to the primary anchor. And since the primary was chosen for the anchoring expected a good obvious choice would be another one like it.
But most all skippers believe no anchor best for all bottoms so a second anchor that is a strong performer where the primary is weak would be an obvious route to take.
The Claw is a very popular anchor but is weak on holding power (just for example as most believe that) so a Danforth would be a good "mate" on the same boat as the Danforth (most believe) has very good holding so they would cover each others weakness.

However two anchors are not enough IMO.

I agree with Eric. You can't have too many anchors. As a rule of thumb you'll need one anchor for each ten feet of boat or part there of. In your case with a 48 foot boat that comes to 5 anchors, minimum.

Bare in mind that I sell anchors and Eric is just nuts when it comes to anchors.
Seriously a stern anchor isn't a bad idea.

We carry and use a stern anchor on the swimstep that is different in style than the boat's main anchor and is sized (with its rode) to be the main anchor of the boat if we deem it advantageous or necessary. Our main anchor is a rollbar-type, our stern anchor is a lightweight but large Danforth-type (Fortress).

We feel that these two types will meet just about any anchoring condition we may encounter in the waters we boat in.

Hi Brian.

Beautiful looking boat the K K 48 and it would enhance any anchor you put on it.

HopCar is correct, you should have a stern talk to your anchor.lol

I believe peter is also correct in that anchoring near coral would mostly be on a buoy, even here in Moreton Bay at Macleay Island they are laying in buoys because the seagrass beds are being destroyed by anchor chains dragging around 360 degrees on the tide.

Regards.

David.

I agree with "manyboats" that you need two anchors, one like your roca and a mud anchor like a fortress. But as he pointed out you also need a third anchor to replace your roca if, God forbid, you have to cut it loose.

Hi David, I agree with your comments about the looks of my boat:-).
Yes, hopefully there will be buoys available near coral and I will use them wherever possible.

Thanks to all for your input, I now own a Fortress FX-37. I chose the Fortress as I can store it dismantled, the Sarca wouldn't fit through the hatch to the anchor well.

Shame about the Sarca not fitting. Both Super and Excel?
Tranquility Base is indeed a lovely boat, the KK display boat at the last Sydney Boat Show,I had the pleasure of a " shoes off" inspection. And, my new deck shoes were still there when I was leaving.
