You guys have been super helpful with a couple other newbie questions, so I appreciate your thoughts on one more. I live on a pretty deep fresh water lake, which has fairly steep slopes from shore. With my current 20 foot bow rider, when anchoring just off shore, I drop about 20' of line in 10' of water. Work great. But now that I'm considering a 31' Sundancer, and see the "rule" is 5:1 in calm water, I'm a bit concerned how to continue to anchor near shore. Since the water depth increases at probably 2:1, if I were actually to use the 5:1 rule, the anchor would likely have to be 300' off shore, in 60' of water; clearly unworkable. And while it was no big deal if my 20 footer broke loose, and drifted to shore, I certainly don't want that to happen with a 12,000 lb boat. I assume I could get away with substantially less than 5:1, but appreciate your thoughts.
