SPIRIT 28
Description
This is a performance-oriented cruiser/racer built by Glastron (a powerboat maker that briefly entered the sailboat market). It was designed by Robert Finch (with Earl Blackwell credited on some sources) and produced from 1979 to 1981, with around 80–300 hulls built (numbers vary by source; some production overlapped with North American Yachts branding before Glastron acquired the tooling).

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them. You should take the same precautions, especially when the data is not from Sailrite. The information on this site is not guaranteed to be accurate.
