J124

12 / 36 - score 54%

The J124 is a 40.7ft fractional sloop designed by R. Johnstone and built in fiberglass by J Boats between 2002 and 2007.

35 units have been built.

The J124 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 fast cruiser. The fuel capacity is originally small. There is a very short water supply range.

This boat has an average score but ranks in the top half. It might be a good tradeoff.
