Re: Frozen rudder shaft Hinterhoeller 28
You're going to have to cut out the stuffing box from the hull... Tearing it out is what appears inevitable, and there may be collateral damage not intended. Further, from the top side appears there is serious interferences that will hinder extricating the stuffing box. Also, if you successfully remove the top half stuffing box I believe you'll still have to remove the bottom. Whereas removing the bottom MAY get you access to split the upper box from your access. A small hole in the hull or from above would be my first attempt so you are no longer working in the blind. I'd use a hole saw to make an access perhaps above and below. A core hole can easily be patched without compromising the strength. Again, just need care to select that first hole for a look see.
