I will get a pic of the starboard damage that is adjacent to the blown out stringer today.

Bow damage.  See the streaks? It appears to be polyester resin that was just dumped in.  That was done in the stern as well but I ground it out already.  The bonding putty is Grey so I don't think I would confuse it with poly resin.  Pretty sure someone has done a bunch of sub par work to this boat.  See the paint. It is representative of the rest of the work.

Again, why rebuild the stringers from the inside instead of the outside? I really do not relish the idea of grinding inside the stringers. Also, is it standard to have one layer of biax tabbing the stringers down because that is all that is there.  As shown in the Pic the bonding putty unbonded leaving the one layer of biax floating in the air, tabbed to nothing.

My goal with this boat is to make the guts last for another 50 years so my kids can finish it however they want when they want. I can change my goal if this boat isn't worth $300 plus a sheet Coosa. Thy plywood lasted a long time. Your opinions are appreciated.  Thanks

In the last pic you can see how the stringers were laid into the boat. The stringers were attached with a bonding putty, so maybe what you think is resin in the aft of the boat may be bonding putty. To repair the stringers I think dbiscayne has the right idea to rebuild them from the inside out. You can buy rolls of 4" or 6" 1708 that are used as tape, might want to consider that instead of cutting your own tape.

Okay. Answer to Rick's questions. I have not used any resins or epoxies as of yet, still grinding.  The resin appears to be polyester  and was already in here.  You can see where the stringers delaminated from the hull.  Looks like whoever "repaired" them dumped the rest of the resin in the bo/om.  I will try to post a pic.

You can see extensive repair to starboard bow. There is also repair about halfway back on starboard. I assume same collision which caused starboard stringer blowout?  Why would core be removed  from next to keel?  Input please I am at a loss.

You can see where core was taken out and not replaced. What was factory?   By the way, cicadas are attracted to grinders.

Haven't processed all you wrote yet but will and will answer. In the mean time more pics to ponder. This boat has clearly been in a significant collision.  See pics of bow and stringer.  Everyone's thoughts would be appreciated.  Should I continue down the Coosa path or switch to plywood?

Where are you referring to? If you are using epoxy, it doesn't harden very fast and can run down and puddle at the bottom of the transom. I hope you plan to install a pvc pipe at the aft and through the drain hole. You will be affecting the lowest point in the boat. Now is the time to do it.

Here is a link to where I explain the thought of the PVC pipe

Here is a link to where I show what is actual problem

Here is a link to Hawgleg's rebuild that shows the PVC pipe installation to keep a drain at the new low point of the boat
