The J105 is a 34.5ft fractional sloop designed by Johnstone and built in fiberglass by J Boats since 1995.
The J105 is a light sailboat which is a very high performer. It is very stable / stiff and has a low 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.
