I wouldn't worry about sanding down so thin. I went with 1/4" strips on my Outer Island because it was my first stripper and I wanted to ensure enough material was there for the fairing stage. But even in the tricky areas where I had to do the most sanding, I don't think I got any thinner than 3/16". Also, consider the fact that a few people use strips that are nominally 1/8", so small thin patches shouldn't be a problem. It might depend a bit on where the thin spots are, though. If they're on the keel, a bit of extra reinforcement may not be a bad idea.

: I realize a glassed hull (glassed inside and out that is) acts like an I-Beam
: with the strips acting like the web of the beam. By this reasoning, the
: thicker the strip, the more strength the "beam" will have. What
: happens if in spots I sand down to a wood thickness of 1/16" vs the
: 3/16" I started with? Should I put an extra section of cloth on the
: inside of the hull in that area to help with impacts (rocks)? I have no
: idea what the actual thickness will be, but I cnan tell my stripping
: wasn't perfect (maybe on my next boat).
