Sea Tow Reliant

Sea Tow RELIANT is a 21' Proline Commercial Assistance Fast Response Towing & Salvage Vessel.  She is ACAPT certified and inspected by C-PORT, the assistance towing industry association of record, to perform Coastal Assistance Towing.

The RELIANT was purpose built by Sea Tow Boston in 2007 specifically to have an "Air Draft" of less than 6 feet. With it's custom folding mast, RELIANT is able to navigate the North Station rail road bridge on the Charles River when the bridge is in the closed position. The RR bridge closes twice a day for approximately 2 hours each time for rush hour train traffic. Sea Tow required a vessel that could navigate the bridge in order to service our members using the Charles River 24 hours a day without delay.

The "RELIANT" is also large enough, powerfull enough and so well equiped that it is a primary workhorse in the Sea Tow Boston fleet. She is a favorite of the Sea Tow Captains because she is extremely fast and nimble. RELIANT does everything a Fast Response Towboat should do and does it well.
