I am considering changing from 15 ft. of chain to all chain on my primary anchor. I have a 456cc and I want to know what is the maximum amount of 5/16 bbb chain this boat can handle or what is the recomended amount.

I have H36 with 275ft chain....no problem
given that, you could probably handle more. Although most people don't need more than 300ft.

hmmm
Maximum....just a guess but maybe anymore then 5000' and I think the boat will sink. What is recommended...if your going to the Pacific Islands, then 300' of chain, otherwise, 20-40' is plenty with an additional 300' of rode attached. Many will claim that all chain is best but it isn't needed unless your anchoring in coral which isn't allowed except in places where that's all they have. If you use all chain, you have to add a snubber to absorb the shock that the rode would normally absorb. What the chain is good for is keeping a horizontal pull on the anchor due to the heavy weight and that's pretty important...especially when trying to set the anchor, but 20-40 is all that is needed for that.

On our P456
We've replaced the chain/rope rode with 300' all chain a couple of years ago. The 44# Lewmar anchor was also replaced with 66# Bruce. The bottom where we anchor is mainly mud/sand. The additional weight from the all chain rode was a concern from this replacement. However, I can not see any visable change to the bow water line. The actual amount used is typically 75' where we anchor using a 5 to 1 or 7 to 1 ratio. Hope this is of help Joel

Our compromise
We switched last summer to 50 feet of chain and 150 feet of rode for our P42 with a Bruce 44. This is for the Chesapeake Bay. We normally anchor in 9 to 14 feet of water. I put out 60 feet. So all the chain is on the bottom and I don't need a snubber. Just tie off on the bow cleat. If the wind comes up we put out more line for the better angle and to absorb shock; up to 90 feet total.

Just curious....
Why go to all-chain if you don't really need it? I don't have a lot of experience, so I'm not an expert, but I have done a lot of research. It appears that nylon rode is superior to chain in every respect save 1..... chafe on coral/rocks. Again, not criticizing, just gathering data. Cheers, Bob s/v X SAIL R 8

It's a mentality thing. Some drive Volvos, others drive Chevys. Some want the absolute safest thing out there and go with the strongest, while others are willing to live with the VERY slim chances that a rode will break. The chain helps them sleep better at night. BTW: there is one more advantage...you can go safely with a 5-1 ratio verses a 7-1 ratio with rode (not a big deal in my book, especially since I have to use a stern anchor anyway).

Yeah, Franklin, I agree...
I was just looking for more reasons. When we finally shove off, it will be with 300' of hi-test in the locker and a LARGE CQR or possibly Spade hanging from the roller. Can't give you sizes because we haven't picked out our cruising boat just yet. Since chain is unavoidable on a cruising boat, the real search is for a better snubber
