I saw this tug working in Southampton. Its lines were striking to my eye so had to build it. FERRIBY’s Mate was very generous with his time providing me with photos & dimensional information for the real tug.
I have not had much sailing time with it due to initial esc failures (since resolved) & it’s 32 lb weight. The little I did run it showed extremely good maneuverability & the need for much practice at the helm.
The hull is Gary King’s TIGER SUN greatly modified to become FERRIBY. All else scratch built.
