[Sonar] Ryder shrouds

I moved my chain plates inboard on my Ryder (239).  I did this to make it
comply with the Rules.  I felt was fairly easy to do, but then I like to do
these sorts of things.

Remove the shrouds, the trim plate on the deck (4 screws) and the three
bolts below deck.  Tap from above with a hammer to drive it down and remove
the chain plates.

Draw on the deck where you need to cut.  Cut with a reciprocating saw.  Use
a metal blade or a finer tooth wood blade.  Make the slot about an eighth
inch larger than you need on all sides.

Check for rot.  Mine had rotten wood caused by water leaking in around the
chain plate.  I cleaned out most of the bad wood with an allen wrench in a
variable speed drill.  The allen wrench fit into the slot and then the drill
rotated it and swept out most of the crumbly wood.  Hopefully you won't find
rot.  You could also enlarge the hole below decks and remove any rot.

In my opinion this part of the deck is not structural and you can make holes
within reason if you need to.  The three bolt below decks do all the work of
holding the mast up.

Anyway back to the best case scenario.  Once you have your slot enlarged put
the chain plate back on.  Use the existing bottom hole and drill new ones
for the two closer to the deck.  Put the bolts in and tighten down.  Get
some two part epoxy. Get the kind that mixes up to a peanut butter
consistency (fairing compound).  Force it into the openings up on deck with
a putty knife.  If you removed rot, maybe fill it all in before you stick
the chain plate back in.

Drill four new holes on deck for the trim plate.  Put some caulk around and
screw it down.

Now your deck won't rot because the chain plate is set in epoxy.
