Hi, I've recently upgraded my boat to a Surtees 575 HT & would appreciate some advice please on upgrading the mooring anchor chain I used on my previous boat. The chain has 10mm links and is 3.8m long with a decent size Danforth anchor(it was overkill for my previous 4.5m tinny) but a yachtie told me to go as big as you can manhandle. The 575 is really a 5.5m boat. Would I need to lengthen it to 6m and could I get away with 8mm links on the extra chain or stick to 10mm. We anchor our boat for about 12 days in a sheltered bay. Thanks very much for any feedback.
Cheers

Wind goes more than 180 degrees during night, there can be a problem. That’s when heavier can help. But better is to reanchor boat with same aporoach. If achor is heavy enough chain will pull around first if going 180 but anchor will only turn on bottom and should still dig in on same bottom. But I am not an anchor so this is literally all theory.. What I do know is with good anchor set up, do not anchor in woody bay rakino with not enough warp out on incoming tide at night, because your too keen to dive ashore to meet a new girlfriend when you have keys to a mates bach. That usually results in boat going for tiki tour and bouncing off rocks in middle of night while you are having a nice time. My boat still has the scars and lady in question is now my second wife. So sadly that is what I consider really hazardous!

Dont forget chain varies in weight depending where made.

Thanks for your advice, No winch and the bottom is sand. Ended up replacing the entire chain with 6m of new 10mm mid link chain. Cheers
