Has anyone considered a way of making the spinnaker halyard internal and yet prevent water ingress when you inevitably go swimming ie have an internal pully system for raising the spinnaker and yet have some kind of valve / tube system to prevent water getting inside the mast. I want to try and clean up the mast a little ie internal downhaul, main uphaul in the luff track and spinnaker uphaul internal as well. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
Hans Runs his Spi halyard down the forestay that makes the mast a bit cleaner; but you have a block up there.
I considered an extra tube up the front of the mast (on the inside) to carry the Spi halyard get decied it might cause more problems than is solves.
