The J40 is a 40.0ft masthead sloop designed by Johnstone and built in fiberglass by J Boats between 1984 and 1993.

The J40 is a moderate weight sailboat which is a reasonably good performer. It is stable / stiff and has a good righting capability if capsized. It is best suited as a coastal cruiser. The fuel capacity is originally small. There is a short water supply range.
