For a fluke or danforth style anchor to set and hold, it needs to lay flat or near flat on the bottom for the flukes to dig in. The chain adds weight to the top of the shaft to help accomplish this. A chain also helps with chafing of the rode so it doesn't wear prematurely.Curious, how does the chain help? I don't have any on my anchor now but sounds like I probably should get some.....
Sounds like whatever you have works for you. However, short of a dozen cinderblocks, I have not seen an anchor which would NOT benefit from addition of at least some chain. Any chance you can post a picture.(I really hate the chain since it has a tendency to scratch the top edge, even the rub rail, of a boat while dropping or retrieving in rough seas when you can't hold it off enough safely.)Thanks Misdirection. I don't have a fluke type anchor. Not sure what mine is called but it is heavier than heck. Never had a problem with it digging in (sometimes digs in TOO well) so doubt I need a chain.
