General Description

2019 Refit 1993 37 Knowles Walkaround Ma Sheila was built from the famous Billy Knowles mold using fiberglass and corecell foam. Ma Sheila is soft riding, fuel efficient and has light tackle world record maneuvering capabilities. Seakeeper. Cabin has galley, enclosed head/ shower and Queen berth.

“Ma Sheila” is a custom 1993 Billy Knowles 37’ Walkaround refit in 2019. “Ma Sheila” comes equipped with a Seakeeper and is considered by many to be one of the finest mid-sized walkaround fishing boats ever built. This Knowles 35’ completed an initial refit in 2015 including Cummins factory reconditioned QSB 380 HP engines with electronic controls. In order to make her a light tackle world record chasing machine, “Ma Sheila” had a complete bow to stern refit in 2019 including a Vetus bow thruster. The walkaround combined with the 488 ft./lbs torque bow thruster will spin this 1993 Billy Knowles 37’ in a 360-degree circle in seconds, making it almost impossible for a fish to get away!
