I was actually browsing through the West Marine catalog last night because I'm thinking about buying a new anchor for my recently-purchased boat. Being a newbie here, I was a little hopeful when I saw this thread title this morning, but...
It seems like the general consensus is that there is no "right" anchor. So, I'm just going to go with the prettiest.
How about this one?
Intended use: Sand/weedy bottom, occasional mud when I go farther inshore.
