I have a Kevlar canoe with a note epoxied on the inside bow, that states it's a special edition Sawyer racing canoe, and regular manufacturer warranty does not apply, and it also has a written signature that appears to be "Castro", any info, or input would be appreciated.

You might look up the Facebook group "Sawyer and other Michigan Canoes", some folks their might be able to help you.

This is the Sawyer Super we own. It is strictly for racing. Gunwhales are too low to water to use for tripping.
