TIH came with two 45lb CQR anchors. One I traded and the second one has hung on the bow for the last three years. These are not my favorite anchors but I know they do have their supporters. My anchor of choice was to be the ROCNA with a possibility of the very similar MANSON as an alternative. ROCNA has recently been in the wars due the use of a lower spec steel after it outsourced production to China, see;
I'm not convinced that the issue is major but ROCNA appears to have made little or no effort to address the situation. As a result I am happy to default to the 60lb MANSON. The Supreme 60 is specked for 45' to 55' Boat Length but the company does recommend moving up a size if you plan to anchor in testing environments. I will only be keeping one anchor on the bow so weight will not be an issue.
My backup anchor will be the CQR 45 (or its replacement) stowed below decks, a Fortress FX-55 partially assembled in the V-Berth and a steel 35lb DANFORTH secured aft as a kedge anchor.
