Hey, Port Orchard...
I have a 1999 Hunter 380, esentially the same hull and weight as your boat and we use a 33 lb Bruce, one hundred twenty feet of chair and two hundred feet of thre strand line.My back up anchor is a 16 lb fortress, six feet of chain and one hundred fifty feet of line. I've never used my back up.I've used this system for sixteen years (three different boats, the 380 I've had for six years. I've anchored all over the San Juans, Gulf Islands to Desolation Sound and then down in your area of the south sound. I've never had a problem with the Bruce. Hope this helps. If you have questions, write me off line. leslieblackwell@comcast.netLes
