I'll assume that you are safely tied up in a marina somewhere. Suggest you do a yellow pages search on chandleries centered about the area where you are. Then phone
to see what they have in stock.
There are *too many* anchor threads already on CF, but if you do an advanced Google
search, through this forum (click on Search, then go down the menu to the adv. G. search), you'll be able to learn all you want to know about anchors and anchoring
. There's even one on bent anchors.
Another option is to order an anchor shipped to you. They're heavy, so it's expensive to do that, try and find out who is closest. You also need chain. There are articles here which discuss what kind and what strength you need. It's not okay to use farm chain, you need it to be galvanized (more discussion).
Good luck with it.
