I have a 2005 282 Sailfish and want to get a new Lewmar Delta anchor. We currently have 1/4" chain and 1/2" line. The delta 14lb would match our 1/4 inch chain but then the anchor is at the very top end of the size chart for the 28' Sailfish. I'd like to get the 22lb Delta (which is on the heavy side) but that recommends the 5/16 chain. Is it a concern to just use my 1/4" chain? I'd really rather stick with the 1/4", it works well with the windlass etc. Our anchoring is primairly for the leeward side of Catalina Island in Southern California. Thanks......
