Notes

One of the earliest trailerable cruising sailboats of this size built in America. Also built by Burr Bros. Boats, Inc. Some built in Finland.
Reportedly, a mold was made and few were built in fiberglass by Sailstar Boats. (Advertised in 1965)
A curious aside: Charles Angle, designer and early promoter of 'trailer sailing', is recorded as being the purchaser of Hull #1, (1954).
Masthead rig:
I: 30.0'
J: 9.5'
P: 26.0'
E: 12.0'
Sailstar FG boats were advertised as being significantly heavier (4000 lbs./1814 kgs).
