J121
2 / 10 - score 57%
The J121 is a 40.0ft fractional sloop designed by Alan Johnstone and built in fiberglass by J Boats since 2018.
The J121 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.
This boat has an average score but ranks in the top quarter. It seems difficult to do much better. It is one of the best possible tradeoff for this request.
