cep32 4 Posted March 2, 2022 Share Posted March 2, 2022 I need to shorten my forestay on the Javelin. It is currently 5mm SS so I will have to take it to a rigging place (mast and all) to get it done which is a bit of a pain. Would Dyneema work if I oversized it heaps? I can get Dynice Dux locally which, if I use say 7mm will give me a breaking load of 7.5T. I figure that the load in the stay should be well less than 750kg (10% of MBL) so as long as I prestretch my splices it shouldn't creep or stretch on the boat. Am I on the right track or just risking a word of pain and frustration? Quote Link to post Share on other sites
Psyche 626 Posted March 2, 2022 Share Posted March 2, 2022 750kg? 7mm is way overkill more like 4mm, what are the other boats using Quote Link to post Share on other sites
Jason128 6 Posted March 2, 2022 Share Posted March 2, 2022 It creeps. You will forever be chasing rig tension changing. at 7mm the weight windage will probably worse than 3mm wire We use 4mm on the prod of a 12. Prestressed splices to 2t overnight to bed them in. It will needs a winch to put it in in the morning, and will be getting soft by the end of the day. Fine for a prod, hopeless for a tensioned rig 3mm 1x19 wire is all you need for a forestry the skiffs and sports boats not running wire are running either pbo or 2.5/ 3mm solid carbon rod.
