Oday 240 has separation of deck from hull and deck is bulging up approx 1/2 inch from hull around the chainplate area. How is the rod chainplate rod inside the boat secured to the hull as it appears to have moved upward also and how can this condition best be corrected?
Oday 240 chainplate issue

The best thing to do is post some pics of the chainplates particullarly inside the cabin where they come through. Some of the O'Day chainplates had brackets mounted to the bulkhead for extra support. I'm not sure how the 240 was set up. The only guy who would know is Rudy Nickerson of D&R Marine. http://www.drmarine.com/
Rudy bought the molds from O'Day when the went out of business years ago. He worked for that company and bought all their parts.
Back in the mid 1990s he contracted a builder in Bristol to build an O'Day 240 to his specifications, and about six O'Day 192s which he called the Weekender.
I remember checking out the Weekender and I know that he made changes in the chainplates by adding special struts inside the cabin to reinforce them. I also remember going inside the 240 which he called the O'Day 25 back then but I didn't pay much attention to the chainplate setup.
If the chainplates on your boat are embedded into the fiberglass, you're most definately going to need to cut into the fiberglass inside the cabin where they enter so that you can find out what the conditions is in that surrounding area.
There's a new epoxy out right now which is put out by West Systems called Six 10.

One of my friends used this stuff on his O'Day 30 and he swears by. All you need is a regular caulking gun. No mixing involved and you can buy extra spouts for it.

Hi I own a 1988 O'Day 240 and have been repotting/rebedding EVERYTHING that is a through and through, consequently I found out how the rods are attached. There is on each side of the cabin where the rods come down from the deck, a Black acrylic/vinyl pry out plate that is in back of the cushion in which is housed this rod. On the inside are two large nuts and a fender washer butting up against the inside of the wood that also is the base for the fiberglass housing. The top nut provides the lock for the rod from the inside of this housing while the second nut snugged up into it prevents the first nut from loosening. On the underside of the deck within the cabin is another nut that is in contact with the deck's underside to provide the pressure holding the rod in place, the chain plate and cover with its four through and through bolts/nuts (lock) provide the deck seal. The cover plate is one piece with the rod/chainplate asembly that goes thru a slotted space in the deck. If you drop the nuts/washers within the hull housing don't panic, they will be found within the storage area under the cushions. The opening is a small diameter for a male's hand so a female would be better able to access these nuts without scraping their hand to bits.My guess as to why the deck is bulging and the deck is separated from the hull at this area is that the whole chainplate assembly move upwards when the sidestays are stressed because these nuts are loose. There may also be damage to the deck from water and wood rot which Mainsail addresses in resealing/rebedding with butyl tape - look up these threads.
Thanks Boomers for your descriptive response. Will check out what you describe. Wondering though why the assembly would move 1/2 inch upward unless the piece to which the chainplate rod attaches inside the boat has broker or moved. Can't see that attachment since it is inside the a channel and I don't see any pry out plate. I can slide a hand up inside this channel but not far enough to feel anything - and it's full of prickly fiberglass bristles as I discovered.
hI AGAIN, i WILL BE WORKINHG ON THE BOAT THIS WEEKEND AND WILL SNAP SOME PICS OF WHAT i HAVE INSIDE OF MINE. cOVER PLATE, CHANNEL AND THE ROD ASSEMBLY IN ORDER FOR YOU TO SEE WHAT i HAVE VERSUS WHAT YOU HAVE. sNAP A PIC OF WHAT YOURS PRESENTS AS AND PERHAPS WE CAN FIGURE IT OUT. i STILL THINK THE ROD IS NOTR BROKEN BUT THE RETAINING NUTS HAVE LOOSENED AND ARE NO LONGER BUTTED UP AGAINS THE INSIDE OF THE CHANNEL (sorry for the caps being locked on - didn't notice until the very end.
