The Ker 40 is a 40.03ft fractional sloop designed by Jason Ker and built in fiberglass epoxy with foam core by McConaghy Boats since 2010.
The Ker 40 is an ultralight sailboat which is a very high performer. It is reasonably 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.
