Re: Anchor Chain Size and Length
toggle quoted message Show quoted text
After two circumnavigations, in two yachts, and a lot of cruising in other vessels including my latest Amel 54, I say that you have to compromise. Of course more chain would be nice on occasion but that needs to be weighed against stowage and a heavy weight in the bow. 100m of 10mm chain (250kg) is about the maximum you can stow and is generally sufficient. If in extremis you can add some nylon rope. I have noted though that when anchoring in say more than 25m less scope often holds quite well. Three to one in 30m of water holds whilst in 3m of water 9m will not do it. However if on short scope and it starts to blow you ain’t gonna sleep well. It is just one of those things. There is only so much chain you can practically have. You can though go for a really good modern anchor like maybe a Rocna, say 40 Kg and 100m 10mm chain and the windlass /stowage. You will have a pretty solid system.
On the gypsy should be stamped the chain size iso/din etc often on the underside. As Danny says you must check it for wear.
