OK, I gotta ask, why would you want to do this?

Knew somebody would eventually ask!
It's an attempt to make a compact J bend to go through the deck of
sailboat near the bottom of the mast through which to take the wires
from the mast into the boat; where they will connect to a terminal
strip.
On another group we have previously discussed which lights are
required under international regulations and where they must be
located on the mast while a) Sailing b) Motoring c) At anchor.
Also the number of conductors needed etc. (About 6 plus a small coax
for masthead VHF radio whip).
The decision, so far, is to not use plugs/connectors/sockets which in
the past ** have either corroded badly (marine conditions) or being
deck mounted have allowed water to get through them into the deck
laminate. Then during the winter the water froze and burst the deck!
(Now repaired).
Each winter for storage the mast is removed and wires disconnected.
The fibreglass boat was made in the 1970s. We have owned it for some
20 years. Overall the project is a major refurbishing including
rewiring the whole boat after some 15 years laid up next to our house.
At least that makes it easier to work on, have AC power available and
access to all ones bits and pieces and tools.
Fixing up boats at a marina 25 miles away can cause one to drive back
home to pick up a forgotten SS bolt or one particular but essential
tool. (Sounds a bit like plumbers who forget their tools eh?)
** The problem started when a previous owner had a new mast installed
following a dis-masting. Whoever did so drilled holes and mounted two
deck sockets that allowed water to get into the deck structure. That
frozen water burst the deck around base of the mast.
Lots'a work might eventually get it in the water again!
Thanks for the question and the advice.
