Rocna 6: suggested chain 6mm

Hi, I recently purchased a Rocna 6 for my 25 ft trailer sailer. Rocna chart suggests 6mm chain. I've already got 8mm chain and 12mm nylon rope in good condition with high quality shackles. So, can I simply connect the new Rocna 6 to the existing system or should I buy the 6mm chain etc? We typically anchor overnight in sheltered bays and can move to another bay if we get caught out in a wind change. Am I losing any holding power by using the 8mm chain instead of the 6mm? thanks

The most difference it's going to make is that you have more weight in your chain locker than you might be able to get away with. If your 8mm chain is in good condition I wouldn't give it a second thought. When it's time to replace you can choose good quality 6mm chain.

I should mention that the boat is 1200kg and there is not any windlass or winch. thanks

You already have stronger chain than recommended and apparently are happy with handling it. Hopefully you dont snag your rode on an underwater obstruction and lose the anchor and have to deal with where to go next. If the bottom is always soft and sandy with no rocks or coral or wrecks on the bottom then it sounds like you have a recipe that is working for you.

The 6 mm is a minimum. The heavier the chain the better--within reason of course.

No windlass means no gypsy which is usually your determining factor on the chain. Nothing wrong with a stronger chain.
