J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Core Issues - Cabin Top

You can blame the construction issues on TPI, not J/Boats. J/Boats severed their relationship with TPI a few years back due to keel box issues on boats constructed using the SCRIMP process.

Yes almost all of our J/30s have the common issues you found too. Good to see you have a "new" J/30 that will last forever with the proper fixes put in place!
