Re: Anchor Chain Size/Lenghth Suggestions (again)

nolesailor,
My response to your question would be that you should certainly be able to pop it out with either body strength or a tug forward from the engine. This, of course, depends on your strength! You will need to be able to cleat off your rode somehow, and have someone power you forward.

I'm telling you, my windlass is a 1000W Tigres with a really powerful battery supply. And it bogs down popping that Mantus free from the bottom at 1:1 and after only setting it normally in light winds. If you set one of these new designs with lots of scope in a real blow, I am sure you will have to use the motor to pop it out at 1:1.

So there is a trade off, I guess. For me, and I would guess for most, the greatest stress is dragging anchor. I am willing to deal with getting the darn thing up, so long as it only does so when I want it to.

Raising the weight of your system is a really different consideration than what we are talking about, so let's leave that aside.

Pulling an anchor out requires the proper technique as you stated. All the new gen anchors ,we have a Rocna, dig in very well and similarly. We have a manual windlass and still use the boat to pull it out. Getting above them then using the boats motor to break it free then allowing time to get it on board doesnt mean you will be dragging it. risking hitting your gelcoat when it breaks the surface. Take you time.

Re: Anchor Chain Size/Lenghth Suggestions (again)

Oh boy, here we go. Listen, and I have a 28 footer that I have been raising by hand for well over 20 years. You def. want at least a boat length of chain. 3/8 is the smallest that you can get a good grip on by hand. Anything smaller will hurt to hold and impossible to get your fingers around, especially when the anchor is hung or dug in real good, or you are raising in a chop. We don't want to anchor in high winds, but you should plan for it. 1/4 inch chain is dog chain. I don't care what the working load say's on the box. It's not practical for hand raising and yes you want the weight of the heavier chain to ease the force on the anchor and lower the angle of scope. Anchor size. go a little bigger man, get the 35 and sleep well, dine without worries in the pub when the squall pop's up. You can really only go too small, not too big. ( with in reason)

Re: Anchor Chain Size/Lenghth Suggestions (again)

Concernnig the above advice concering increasing anchor size...Would a Rocna 15 (33 lb) be overkill? My number one concern is to sleep well at night, I'm happy to deal with pulling the anchor up the next day - with engine - or whatever other means. Would a 33 lb anchor be too much of bear to pull up so that it's unnecessary overkill? Thoughts? I mention Rocna now as opposed to Manson as I seem to be of the opinion that the shank size might fit on my anchor roller better as we are getting bigger in anchor size.

Have the Rocna metal quality issues been resolved that have been discussed on this board (and elsewhere)?

Thanks,

Brian

Re: Anchor Chain Size/Lenghth Suggestions (again)

Others will undoubtedly tell you that you need a larger anchor. You can't get too big of an anchor, unless it gets ridiculous, and larger anchors will always hold better than smaller ones. However, the Rocna 15 weighs over 32 lbs (listed as 33, but it feels heavier). Add to that the weight of the chain, shackle, and the bottom that will inevitably come up when you retrieve it, and you'll have a real workout when hauling it. If you're up to it, knock yourself out...

I use a genuine Chinese Rocna 15 with my 35' O'day, and I sleep well at anchor. Realize that the O'day 35 is considerably larger than a Catalina 28 (about 35% more deck space). I have a friend that owns a Sabre 28, and he uses a Delta 25. The Rocna fits very well on my bow roller, which is why I decided to keep it after the anchor wars started. For a Catalina 28, I believe that the Rocna 15 would be overkill.

I also believe that the metal shank quality issues have been addressed by the new owner of Rocna (CMP), and they vow that they will stand behind the product. You have to decide if you feel comfortable with the new owners and their warranty.

I hope that this helps.

Re: Anchor Chain Size/Lenghth Suggestions (again)

I use a 7.5KG claw, 15' f 1/4" chain curently, on a jenneau that is inch for inch the same size, but 2000 lbs lighter, and have no issues with that combo. Altho I do plan to go to a 10KG claw or equal, 30' of 5/16"ht chain with 250-300' of 9/16 or 5/8" max line. We have 14' tides here in puget sound, that is what, 100' of extra line needed just for the tide part of the equation! much less the 20-40' of water one has to anchor in!

General recommendation is 1lb anchor per foot of boat length, 1foot of chain per anchor manufactures recommendation. Then up size one or two depending upon the how much over 40-50 knots of wind you will be in. "MOST" manufactures sizes are for about 40 knots of wind speed.

Re: Anchor Chain Size/Lenghth Suggestions (again)

Thank you all for the responses/thoughts/suggestions..

I think will proceed with the Manson 25, 30' of 5/16 chain, and 200' of 1/2 nylon rode. Concerns over the ability to free a larger anchor vs. what is really needed lead me to believe a Rocno 15 is overkill for our purposes...

Thanks again for everyones input! Much appreciated...

Brian

Thank you for the follow up! I believe that I would have made the same decision.

Re: Anchor Chain Size/Lenghth Suggestions (again)

It amazes me when dudes go for the smallest anchor and chain they can get away with, rather than the biggest they can handle. If you can hand raise a 25 pound anchor, so can you a 35 pound. If you have a windlass, there is no excuse not to go bigger. When I hold 1/4 inch chain in my hand, I laugh at the thought that there are dudes out there anchoring with it.

No windlass...otherwise the decision to go larger would have been easy. That is a luxury that will unfortunately need to wait until the next boat... Agree that 1/4" likely to small and decided to go larger...
