Has anyone tried using the construction foam that expands as it hardens? I was thinking this would reduce the rattling noise inside the mast, any thoughts? p.s. does anyone have knowledge of a good supplier of stainless steel nuts and bolts? Thanks, -Sean

wires
I hear that if you put plastic ties on them and not cutting off the end of the ties, it will reduce the movement and stop the noise. To do that you would have to disconnect the wires, attach a line on the end and pull it throw, put the ties on the wires and then pull the line back. Sounds simplier then filling the mast with foam.

Wire ties work well, and .....
you haven't created an impossible task when you need to replace the wires in the mast. Of course, the foam will not work if you have internal halyards.....

Try Cut Foam
If you use the spray in foam, it will be difficult to get it to penetrate very far into the mast. My AF D-18 has cut foam in the mast. It is for flotation rather than for stopping rattles. You can cut a retangular cross section of foam and shove it in. When I added a mast light, I pushed the foam out with a long pole and then put in the wire. I then pushed the foam back in. It was in about four foot lengths, as I remember.

Sprinkler pipe
When I added new wiring it would not fit in the mfg. conduit that was fastened to the mast so I went to Home Desperate and bought a roll of 3/4 sprinkler pipe and it naturally wants to stay curved so when I inserted into the mast it hugged the inside walls of the mast then I tie wrapped at the top and bottem to keep it from moving then fished my new wiring in. Quick,easy and cheap Here's a link for hardware

Pipe insulatio
round foam pipe insulation, you can slide it over the wires already in place, comes in 4 ft sections of different diameters fron 1/2 in up.

I'm with Bob on this one. My last boat had a lot of slap inside the mast. I bought the 4'lengths of 3/4 plumbing insulation and fed it up inside the mast from the bottom. I fed it around the coax cable for my VHF antenna. I used a figure of eight with duct tape to join each one, in case I ever wanted to remove it. It worked great. That was twelve years ago and the new owner says it is still as quiet as ever.

Don't use the spray foam
Sean, If you have internal lines like halyards that run inside the mast or reef inside boom do not use the expanding spray foam. You will stop the noise from the wires but also loose the use of your lines. They will get stuck in the goo.

Pipe Insulation is a Good Idea
I wish I had thought of it. It would have been easier to use than my rectangular insulation.

Don't use canned foam anywhere
that you might want to work in later. The stuff is strong, tough, and sticks like a brother. When I wired the mast on Bietzpadlin I placed three cable ties 120 degrees apart in groups every two feet, pulled them in with a messenger line, secured the line so that the connections were not supporting the wire and have not heard a wisper from them ever since.

Wire Rattle
I'm with Franklin. Cable ties. I used this technique - cable ties every 18 inches in a spiral pattern stops any rattle.
