Hi drfilberth,
I’m the current owner of #92 and the waterline striping is actually in the gelcoat and not an added layer. From what I understand it was an “original option item upon new purchase”. #92 was in an accident on the road and it was refurbished by Vince from Columbia Yachts. He was one of the manufacturers for a brief while and may have details on the striping locations. If not, I’d be happy to take some measurements for you.
