waikiore 499 Posted May 25, 2024 Share Posted May 25, 2024 You would not leave one unpainted if you wanted long life as the UV will get at the Epoxy, doesnt matter on a TP or a full on race boat as they are not required to last. Quote Link to post Share on other sites

motorb 49 Posted June 10, 2024 Share Posted June 10, 2024 I've often wondered about this to replace my boom... Are there any issues with galvanic corrosion that need to be taken into account? What about general requirements for maintenance inspections and/or surveys? Quote Link to post Share on other sites
Psyche 842 Posted June 10, 2024 Share Posted June 10, 2024 UV protected carbon spars should last more or less indefinitely provided that they have been designed correctly and not subject to point loads. Unprotected the resin will degrade due to UV but its a relatively slow process, and given the cost of them Im pretty sure that most people would coat them. Carbon fails catastrophically, i.e. your boom will just break when its had enough, it's electrically conductive so maintenance would include making sure any metal fittings are not fizzing, nothing is rubbing and any UV coating is still intact.
