IMP produced boats for the Red Fish Boat Co. of Clarksville, TX for a few years in the late '50's and early '60's. When Red Fish Boat Co. declared bankruptcy, Iola Molded Plastics (IMP) bought the molds and jigs, and began production under their own name.
The early boats made by IMP for Red Fish are now very collectible, some selling for buckets of cash. I'm in the process of bringing a 1961 15' Red Fish Shark runabout back into shape. You can view some "Before restoration" photos of my boat at http://myboatproject.3dup.net
There is also another brand-new site for Red Fish Boat owners and fans at www.redfishclassics.com
