Hand laid molded fiberglass top in wind deflecting design with powder coated aluminum reinforcing grid. Fiberglass white exterior, with choice of white or ivory interior. Choice of two hardtop sizes; 54%u201D x 70%u201D and 63%u201D x 84%u201D (add $100 for larger size) owners of boats in the 17%u2019 to 21%u2019 range will likely prefer the 54%u201D x 70%u201D top, although if you are a salt water spin caster or fly fisherman with a larger boat, the 54%u201D x 70%u201D will provide plenty of coverage and minimum interference with casting. The 63%u201D x 84%u201D has been installed on boats to 34%u2019 with 9%u2019 beam. This top is nearly 37 sq. feet and provides plenty of coverage for larger boats.
