We own a 2007 Tartan 3700 with a Novis carbon fiber mast. We have been very happy with both the boat and the rig. Currently, we are undertaking some winter work including replacing the RG8X VHF cabling inside the mast with RG213. Apparently, the current wire run inside the mast passes through a mesh sleeve that is anchored at the top and bottom of the mast. I wondered whether anyone on the list might have undertaken a similar project? We're wondering how difficult a job it is to remove that mesh sleeve in order to run the new wire. In particular, are there any obstacles in there like zip ties or other anchoring of the sleeve inside the mast? Might there be any pictures or diagrams of the inside of the mast that are accessible online? Thanks so much for any responses.
