Our other polyester only dock lines are 7\/8&#8243; (22mm), almost four times the weight!<\/p>\n<p>When we started using these lighter dock lines we assumed they would be switched out to the heavier set once we were secured. However, in practice the heavy set are only used when we are stored in the water.<\/p>\n<p>The lack of stretch is an advantage as long as the hardware on the dock and boat are up to the shock loads in a surgey marina. The boat part is easy, the dock part can be more difficult. Although we have yet to pull a dock cleat off its mounting, we are always wary of the risk. Sometimes in rough marinas we will switch out the high modulus lines for stretchier material.<\/p>\n<p align=\"center\"><img loading=\"lazy\" decoding=\"async\" height=\"154\" alt=\"high-modulus-dock-lines-21\" src=\"https:\/\/setsail.com\/wp-content\/uploads\/2010\/01\/high-modulus-dock-lines-21-1.jpg\" width=\"300\" \/><\/p>\n<p>A word on knots. Although bowlines weaken the break strength of high mod cordage, they are convenient, and we have  used them without problem. You do have to leave the knot loose, as shown above. Otherwise it is likely to tighten itself and be extremely difficult to undo.<\/p>\n<p>The FPB 64s come with both dual braid polyester and high modulus sets of dock lines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You are looking at a chafe section on the high modulus dock lines we have been using aboard Wind Horse. <a class=\"read-more\" href=\"https:\/\/setsail.com\/hi-modulus-dock-lines\/\">&#8230;Read More<\/a><\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[49],"tags":[],"class_list":["post-10127","post","type-post","status-publish","format-standard","hentry","category-fpb64-notes"],"_links":{"self":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/posts\/10127"}],"collection":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/comments?post=10127"}],"version-history":[{"count":0,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/posts\/10127\/revisions"}],"wp:attachment":[{"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/media?parent=10127"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/categories?post=10127"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/setsail.com\/wp-json\/wp\/v2\/tags?post=10127"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
