Operational history
In a review Michael McGoldrick wrote, "Many people regard the Sonic as a close approximation of the very popular Tanzer 22, and the hull and sail plan of these two boats are believed to be very similar. However, the Sonic 23 was designed from scratch by Joseph D'Alessio, and it comes with a sightly larger cabin with a better layout. (It has sitting headroom which increases to 6' with the pop top.). The Sonic's interior room may give it the edge over the Tanzer 22 which is known for being a good sailing boat, but which suffers from cabin which appears a little cramped. From this perspective, the Sonic may be a better choice for cruising."
