here is how it is on my 30
My old 27 did not have a conduit in the mast. My 30 has internal halyards so the previous owner had to install a conduit to prevent any fouling types of problems. Drop the mast (very light and fairly easy on a 27, on a 30 it is about 40 feet high and weighs 150 or so lbs). Run the wire from the top (likely have to drill a hole in the mast head) into the conduit if you have one. If you have a conduit you likely have a string running through it that is tied off. That is how they got the other wires in. So run another string along with the wire to pull the original string back out. At the base of the mast you will want a connector or in my case inside the boat is a junction box for disconnecting the wire for future mast removal. The mast step has a large hole in the middle so that is no issue. The deck will have a hole in it. If you are lucky it may also have a short section of pvc pipe to keep water out... Anwyay drop a weighted string down the compression post and drill a hole in the back side of the post near the bottom to bring it out (on the 30 that is under a seat and hidden, on the 27 I am not sure where that is). At this point you can likely finish the project. Seal the wires at the base of the mast to prevent water leaking into the deck.
