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.
