I purchased a hunter 27 1979 in october 2003, when i put the boat in the water 3 weeks ago, i notice a strange slapping inside the mast.This sound,is coming from the electricals wires and the vhf antenna that are inside the mast.I tough of removing the spinaker pole track in front of the mast to see if i can drill a hole to reach these wires. This slapping sound,is driving me nuts at night. Any suggestion to fixe that problem without unstepping the mast. Thank's Marc

This is one thing you might try,
go to Lowes and get that expanding foam insulation stuff in a can ( with the straw ) then drill a very small hole ( that just fits the straw) every 5 to 10 feet or what ever you can reach, spray the foam insulation into the mast. This should lock down the cables inside the mast. the only thing is the internal halyard(s) might stick so before you use this foam coat the halyard with lard or something you can wash off the line , please note that the foam is not that strong so you should be able to work it thru the insulation after it has expanded. I have used this on a San Juan 21 mast and it worked great. Locked the VHF cables without locking up the internal halyards. Do at your own risk, but it worked for me. Baums Rush

Quiet
I pulled the cables with a messenger line attched to the end, put three relatively strong plastic wire ties every three feet (each "tail" at a third of the way around the wire), clipped the ties to be slightly large than the mast radius, and pulled the cables back down the mast. Sleeping was not longer a problem. This idea came from the archives.

Has the easy answer! And it works although I put my ties every 12 inches to be sure to be sure.

Foam pipe insulation
Another common solution is to use 3/4" pipe insulation. I've seen it in 3 and 6 foot lengths, and is split along the sides. I drilled out the rivets of the mast foot and head and simply pushed the foam pieces up the mast over the electric wires. I had to go from both ends because the spreaders have a bar inside the mast that creates a narrow spot. You don't have to pull the elctric wires out. I had to buy a rivet gun - a whole $8.00. I got some stainless steel rivets for free, but they would cost another $5 to $10. The foam was another $10 or so. Ooops, I just noticed you're in Montreal. The prices above are in US$. I got everything at Canadian Tire (except for the free rivets).
