[Rhodes22-list] silencing internal mast cable slap

[R22RumRunner at aol.com]

Mike,
Going from the top down is a piece of cake. It's easier putting it in from  
the top than it is from the bottom. I believe you are over thinking this. 
All  you are doing is filling a void so cables don't slap.

Thanks Rummy!

I slept on the problem and first I'm going  to try easing a 1 x 2" or a bit
of skin-and-frame kayak rib stock (roughly  1/4 by 1 1/4) up from below.  If
the cabling passes in front of the  spreader bolt I may be able to ease the
insulation over it and just keep  adding sections from below.  If the 
cabling
passes behind the bolt  then I'll either have to remove it temporarily or do
as you suggest (which  is what I'll try next).

Adding them from above is a good idea, but the  radio antenna cable "comes
out" of the mast pretty far from the end (about  8") and I'm worried about
coaxing the insulation around it from the  top.  Plus, from below there's
enough space that I was able to tape  around the insulation and did so about
every two feet.  That's  probably way overkill and I'll probably start to
find shedded tape pieces  in about 15 years falling inside the mast, but it
seemed like a good idea  at the time.

I'll let you know how it works out.

Today I'm also  replacing the rudder tiller with one from Stan; mine was
about to give out  due to rot at the bolt hole between the rudder "cheeks". 
Also on the list  is to get Muireann's new Garmin GPS/depth finder 
installed. 
We're getting  ready for a two week trip to the Outer Banks!  One week
cruising the  sound side of the barrier islands and one week with family in 
a
house at  Kitty Hawk with frequent day sailing I hope.
