I'll second the Rocna
Linda, when we bought our boat last year I speant a couple of months researching anchors on the internet and elsewhere. A large majority of people in Georgian Bay use the Bruce or CQR, successfully. Most have never heard of the Rocna judging by the blank stares I get when I tell them what I have.Depending on where you are anchoring, you could be on sand, mud or heavy weeds. Beckwith, Giants Tomb, Christian Island, Kilcoursie Bay all have clear sandy bottom and a dream to set your anchor. If you head into the inner islands like Beasuiliel, Moon etc. you will find mud and heavy weeds. Canadian Shield or not we tend to avoid the rocks. The Rocna is heavily favoured on many of the forums by anyone who has tried it and decided to pruchase one. Last year we anchored out over 30 nights in varying conditions. Of course over at Beckwith I could see the anchor and had set within 5 ft. backing down. We went through several nights with wind shifts and held with no problems including 270 deg. over two nights with 20 knot winds inbetween. We set in heavy weeds on the inside of Mermaid Island and held for sveral days. Came up with a 5ft. dia. weed ball, my son had fun pulling that one off the anchor.I'll be at the boat this weekend, probably come up Thurs. night, spend Fri. at the marina and 50/50 out somewhere Sat./ Sun. / Mon. We're at BayMoorings. Feel free to stop by and check ours out if you wish. PM me for my cell no. if you want to drop by and I'll gladly discuss it further.Scott
