The Glider fish 10,o x 23 x 3 1/4 
the  roots to this big board design run back to the early ’90s when Skip Frye first got jazzed on tapping into ancient Hawaiian trim. The glider Fish Simmons is a modified version with some discovery and experimentation period of these big boards he rediscovered some of Bob Simmons design principles and applied them. Its key characteristics are the 10” tail block with a swallow tail outline, as well as the Simmons influenced concave bottom and shallow belly roll entry. 
This board commands a lot of respect in the line up with it effortless glide and unfathomable down the line speed its not for kooks.
