Something that might help is the Wasp from 68, her sister. Deck to design w/l: 52 ft 2in. Recommended boot top 33 ft above baseline. Flight deck above baseline: 81 ft 8in. If you cut at the design w/l, the black boot top strip would be 3.5 ft. Here is the blue print location: https://archive.org/details/cvs18bogp1968

Other ships from the Renwal package may be there too.
