Nearing the End of Our Chain - Mooring Chains Tested
Practical Sailor pulls its test mooring chains after 2½ years in the water to have a look. A trail of rusty metal tells the tale.
Practical Sailor dropped seven different lengths of 5/16 mooring chain in Long Island Sound 2 1/2 years ago. We reported on the initial inspection and the one-year inspection. After a quick look at the chains at the two-year mark, we left them in the drink for another six months and then pulled them. During the test, all chains had the upper parts exposed to air twice a day and were subjected to constant wear from waves and tidal changes. When we retrieved the chains for the final time, we found the greatest loss of material just below the halfway points in the 5-foot lengths. Chains we tested were Acco, Campbell, Chinese, and Suncor. Chains tested were galvanized, zinc-plated, and stainless steel.
