More on Cable ties...
They do work. I only placed one tie every three feet, but made sure I put it at plus 120 degrees from the last one. This is inside a H25 mast that does not have the PVC pipe installed for wire raceway mentioned. Fewer ties should reduce chafe on the internal halyard. If your boat is big enough to have the pipe in the mast, then you DEFINITELY want to install your wiring in it. I also agree with some previous suggestions that if you attach the halyard to a toerail, handrail, or any other solid object a few feet away from the base of the mast, and then tension the heck out of it, the halyard should not bang inside the mast as there is no wind inside the mast. Only wake, big waves, or thrashing about inside the boat would cause the halyard to bang on the inside of the mast???? I keep all four internals tightened at dock/anchor and do not have any issues inside a 34' mast. Please let us know what works.
