The J100 is a 32.8ft fractional sloop designed by Johnstone and built in fiberglass resin infusion with balsa sandwich deck and hull by J Boats since 2005.
The J100 is a light sailboat which is a very high performer. It is stable / stiff and has a good righting capability if capsized. It is best suited as a racing boat. The fuel capacity is originally very small. There is a very short water supply range.
