The Achilles 840 is a 27.75ft masthead sloop designed by Chris Butler and built in fiberglass by Butler Mouldings Ltd. (UK) since 1979.
The Achilles 840 is a light sailboat which is a good performer. It is very stable / stiff and has a low righting capability if capsized. It is best suited as a day-boat. The fuel capacity is originally small. There is a very short water supply range.
