Put my new boat in the boat park at the weekend. It has a carbon mast. It now lives under a Pylon. When I was putting the mast up, and indeed when it was rigged, I got some monster shocks from the mast. Not only did it shock me many times it was making an crackerling sound?!
I know there is a field given off by Pylons but this seemed much more intense than I would have expected. Also does anyone think this could affect my mast! Edited by Jack Sparrow |

thanks 'slop'... that link seemed to be talking about salt water fatigue on carbon epoxy laminates. Was there another paper you were thinking of?

Thanks... I must admit I think I will ask to move my boat. Trouble is most of the dinghy park is under the plyons.
I imagine 'salty' friends mast went BANG!!!!!!! and l hope his friend didn't go bang too! |

I just thought... my space is on top of, what look like two cesspit metal vent pipes. Presumably going down into a tank (metal?) The tie down points are metal chains in concrete and I'm only 60 feet from the pylon base. Could there be a circuit of sorts being set up here?
