I think we might need a mini regatta somewere...lol
only 20 footers and no later than hmm 85 or so? when did they change the style?
Hallett changed the style back in '88 & '89 when the introduced the 210, which is still in production today.
1986 was the last year they offered the 23' Day Cruiser, which has the same lines as the 20SS.
