The J28 is a 28.5ft fractional sloop designed by Rod Johnstone and built in fiberglass by J Boats between 1986 and 1988.
71 units have been built.
The J28 is a moderate weight sailboat which is a reasonably good performer. It is stable / stiff and has a low righting capability if capsized. It is best suited as a coastal cruiser. The fuel capacity is originally small. There is a very short water supply range.
