On my boat, Silhouette, CR38, #43, when I replaced several cables in the
yard in SF before sailing up the coast to Seattle, I found someone had
injected expandable foam in several spots in the mast presumably to stop
the wire bundles from banging around. Using a steel fish-tape I was able
to clear a path by repeatedly pushing it in and pulling it out a short
distance but that was only after I had cut the factory installed "hooked
end" off the fish-tape and sharpened/tapered the new end a bit. Once I
bored the first hole and got it to the end of the mast I reformed the
hook and pulled a 1/4" line through to open up the new path further and
then pulled the new cables after that. Getting the 1/4" line thru
required a bit a sawing back and forth but actually went smoothly with a
person on each end. Took a bit of effort but in the end it worked out
fine. YMMV.
Regarding the deck vs spreader light discussion, we have both. The
forward deck light, part of the steaming light assembly, proved useful
as an additional "anchor light" of sorts in crowded and busy anchorages.
The masthead light may be easily missed by small boats speeding around
crowded anchorages. We often left the fore-deck light on to better
illuminate our position. The spreader mounted lights were invaluable
when making sail changes or reefing mid ocean and helped the helm
person see and track the process when wind and sea condition's made
voice communication difficult. We found having both was a blessing.
