For my 35, I have 30 feet of 5/16” chain and 150 feet 9/16 nylon. It isn’t likely that our boats could break ¼” chain, but the heavier weight helps with bigger chain and you get more tolerance for losing a little to rust. Likewise with the line, even ½” new un-chafed nylon is very strong. We used about 100 feet of scope during hurricane Charlie when we had ½” nylon and 10 feet of ¼” chain and the boat did quite well all night like being on the end of a bungee cord ride. The danger is CHAFE in the near term and the line getting old and worn in the long term. After the storm I decided to go one size up for everything. For the Bay and likely Florida as well, 3X the usual water depth you anchor in of chain allows one to fit in with all the cruisers laying to 3X scope on their heavy 3/8” chain. Back in the day I would use 5x-7x scope on the nylon and need a lot more room than they did. Now in 8-12 feet I usually anchor in I use all 30 feet of chain and maybe 6-10 feet of nylon and it works well.
Joe Della Barba Coquina C&C 35 MK I From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Bruce Whitmore via CnC-List Sent: Monday, October 2, 2017 9:59 AM To: C&C List <cnc-list@cnc-list.com> Cc: Bruce Whitmore <bwhitm...@sbcglobal.net> Subject: Stus-List Anchor chain & rode advice, C&C 37/40+ Hello all, We have a 1994 C&C 37/40+, and the anchor chain connected to its primary anchor, a 35 lb. Delta, is fused together with rust. The chain is also about 20 ft. in length, which I suspect is too short, as the conventional wisdom I think is that chain at least as long as the boat is highly recommended in order to keep the anchor set. Then there is the line, which is about 150 feet, which equally I think is a little short, though we are located on the west side of Florida where anchoring in 20 feet of water is almost an impossibility unless we're stupid enough to set anchor in the middle of the ICW. That said, we will eventually want to be doing some cruising down into the Caribbean, so I'm thinking carrying some additional rode poses little downsides. Finally, I've read that the recommended line size is 1/8" for every 9 feet of boat length, but of course that is somewhat relevant as to windage and boat weight. I consider our C&C to be relatively low both on the windage and weight scales, especially compared to the 40 foot powerboats I've seen out there. The 1/2" line (which is on the boat now) has a breaking strength of 7,500 lbs., but I presume the issue is more about chafe protection than breaking strength per se. So, the questions are as follows: 1). What size, type and length of chain would you recommend? We don't have a windlass now, but may eventually put one in. 2). Should I go with 9/16" line vs. the 1/2"? What length would you recommend if you were going to consider cruising in the Caribbean? I'm thinking of carrying 40 ft. of BBB chain and 250 ft. of rode on the primary Delta anchor, and perhaps a little less on both chain and line for our secondary (a Danforth), though I'm not sure that carrying the lesser amount on the secondary is advisable.
