The Gem 550 is a 18.04ft fractional sloop designed by Rob Humphreys and built in fiberglass by Central Boating Services since 1976.
40 units have been built.
The Gem 550 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 day-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.
