Well I'm back on the job at least until it's too cold to work in the garage and we shut the house. Started stripping the varnish from the inside using a heat gun and an old sharp putty knife. Technique works pretty well but hard to deal with intense curves with a flat blade. I bought both Total Boat Total Strip and a citric stripper but am hesitant to use either-so far. Getting too cold for either. Stripped about a third of the interior, then couldn't wait to see what was under the canvas, so I gleefully ripped it off. Not too bad by my estimation as to planking. There are two broken planks plus the sheer line will need a bit of planking. I'm told using white cedar is best as not as brittle as western red cedar and you can stain it to match the red planking. Looking at the bare bottom, one could see that 6 ribs had been replaced and several planks, thus a repair had been done at some juncture (1965 build). What is the filler in pink (last picture)? Also, looks like we have 15 broken or cracked ribs. Should I build a steam box, use PVC, or food grade plastic bagging from UNI? I will continue to work on the interior and the rest will wait until Spring. Happy Holidays Trippers.
