1+ to recommendations for a serious evaluation of this issue by someone who really knows boats—naval engineer, architect, whatever, unless of course your sailing venue (current and future) is inshore in reasonable temperature waters and perhaps within easy reach of rescue and that you require all on board to wear PFDs all the time, etc. Like most on this list, I am game to tackle most any boat repair, upgrade, modification, etc. However, and often at significant cost, I pay a professional to do jobs that are either beyond my wheelhouse or would require so much prep and research that it would take forever(allowing for amateur mistakes and redoing certain jobs when the first attempt goes ‘awry’ for one reason or another). For any repair or upgrade that might send the boat to the bottom if it went awry (standing rigging replacement, hull deck joint refurbishment, centerboard pennant replacement, stuffing box issues, cutlass bearing replacement, etc.) I use a pro. Of course with a ‘well found’ boat like C&Cs, there is seldom an issue with a design flaw at the seaworthy level—in fact I am confident that my boat design, whatever the details, resulted in a boat that is ‘smarter’ than her skipper and she will only permit me to screw things up but so far before her design saves my a— once again!
Most boat issues really aren’t ‘rocket science’ and are amenable to reasonable DIY fixes. IMHO, this keel wobble issue probably requires a nautical ‘rocket scientist’ (naval engineer, architect, etc. to have a look! Charlie NelsonWater Phantom1985 C&C XL/kcb Sent from the all new AOL app for iOS
