Morning everyone, I'm fitting a new anchor chain for a triton 24. I'm going north for 3or 4 months next year. I've alaways used 8mm gal plus nylon rode but I'm thinking of dropping to 6mm all chain. Any thoughts about whether 6mm is heavy enough? Reason for size change is to prevent abrasion but still keep weight down in the bow. Appreciate any thoughts.

G'day, how much chain were you considering?
I'd think 30m of 6mm certified/rated gal chain with 50m of 12mm nylon would be great if your trying to keep weight down, I haven't looked into it, that's just off the top of my head. Look into the SWL of the certified 6mm chain.
cheers

For some reason I got this ad on Facebook this morning. Looks expensive but sets of the Ultra nicely! Interesting reading on the stats.

It is not just the strength but the weight of the catenary that is important. If you are going to spend some time in chop then I would veer towards the heavier chain. Pulling chain tight is never fun and should be avoided - the 6mm has much more chance of straightening in a nasty blow, which would not be good.

If you are going to the coral you will need 30 metres of chain which weighs about 50kg (8mm). I would recommend an anchor winch and look at a way of getting the chain weight back in the boat as far as the mast bulkhead. Then you can have heavy chain and a nice sailing motion too.

When anchoring in the rough I always use a snotter to reduce shock loads on the chain.

On my 32 footer when heading north I have 100metres of 8mm chain. Glad I had it when caught in one of those storms two years ago . In my opinion there is no better peace of mind than to have more than enough chain on board. It may not do anything but it makes you feel better when that wind blows.

I use both, 6mm for 10m then 8mm for weight going back to 6mm. Gives me 30m of chain I use a stretchy piece of this silver rope for the snubber. This on a Seaway 25 based in Cairns.

Been through some good blows and it's always held nicely. Not a huge weight saving but better than nothing.

Thanks everyone, I normally have 30mtr of 8mm chain plus around 40mtr of nylon. However as my back is not what it was I was thinking of running 6mm all chain to avoid chafing . I would never tie off hard on chain(great way to damage things) and always use a nylon snubber. I could run an anchor weight down the cable to help with the lay of the chain. Its just that an all 6mm chain is lighter than an all 8mm chain on a small boat.
Thanks

This appears to be top of the range.
Each piece individually tested.
I could not find any prices.
