I know its been a while for this thread, but i am buying one this week. Just sold my Sonic 23'. What a buyers market out there!!!!
The one I am looking at has a Yanmar Diesel with less then 30 hours. Harken roller furling, barient self tailing winches and more.
The one thing they did do is raise the boom when they installeed the wheel.
It looks kinda whacked. i realize they upgraded this on the 1977 models.
Maybe Ill drop it down.
