The Cats will connect to three propellers through Reintjes WAF665 marine gears from Karl Senner.

Designed with a minimal operational draft of 6', the new towboat’s pilothouse's retracted eye level above the waterline will measure 22' and will have an extended eye level of 37'6".

All four of the boats are under construction at Eastern’s Allanton, Fla., facility.
