I have owned several boats and was a rigger and warranty repair specialist for Hunter, Catalina, and Chrysler '78-84. I sold my Hunter 30 last year when someone gave me a Chrysler 26 swing keel. Eventually I will put her in the ocean and sail the Bahamas BUT not until I have made a few mods.
The C-26 was one of the cheapest boats ever made. The bulkheads are particle board and after 30 years have started to disintgrate. Replace them with solid 3/4 ply before you put her in pounding ocean seas. The keel trunk on these boats often cracked and leaked so it needs to be beefed up where it meets the sole and also on the outside add a couple layers of roving inside the trunk or you will be on the bottom of the ocean in a few minutes.
The main hatch and companionway are big enough to drive a truck through. That scares me. A knock down could be disastrous but I made solid oak 3/4" boards to close her up in heavy weather. I still have to rebuild the main hatch because the lips are only 1/2" wide and that is very inadequate. I plan to make them 1" wide and 1/4" thick and replace the slides with 1/4" aluminum channel instead of the dinky little piece of teak that it came with.
I also plan to move the outboard to a well built under the cockpit so it becomes an "inboard" but that is personal preference. I just hate the motor hanging off the back and that huge hole in the stern will be glassed over so I have a watertight lazarette.
