Alumatech marine is a family run business based in Plymouth Massachusetts. The Costa family includes four generations of watermen who made their living off of their passion for, and understanding of, the sea. Running tugs in Boston Harbor, crew transports in the Gulf of Mexico, commercial offshore diving operations, and a large fleet of fishing boats is all in a seasons work. We understand what works in dynamic marine environments because we have seen products fail and the resulting costs-therefore all of our products are built specifically for the environment and expected use.
