What type of anchor ?

[alanw]

I was outside of DP harbor last weekend and remember thinking it was a good time to try out my anchor (grappling type) but I ended up just using my kelp clip instead. After reading this I'm glad I didn't drop the anchor. I have a hobie anchor trolley setup that has about a 1' bungie connecting the two ends of the trolley rope. Think that's good enough to keep from getting flipped? I've got the anchor tied to 50' floating yellow poly crab trap rope from west marine. I think I'll dump it for the 550 cord since the trap rope takes alot of space and seems like a pain to keep untangled.
