The Adams 21, also widely recognized by its original moniker, the Seahorse 6, holds a significant position in maritime history as the first production model from the drawing board of legendary Australian naval architect Joe Adams. Introduced in 1977 and primarily manufactured by Jarkan Yachts in Australia, the vessel was designed during an era when Adams was transitioning from his work with Ben Lexcen (then Bob Miller) to becoming a dominant force in performance yacht design. The boat was conceived to bridge the gap between a highperformance racing dinghy and a capable coastal cruiser, offering a lightdisplacement platform that could be easily trailered. While most were constructed in solid fiberglass, a limited number of specialized variants were produced in aluminum, such as the 1985 "GetOUTside" model.
