Galvanized Steel Boat Trailer Tongue 84″ Long 3″ x4″ Tubing 3/16 ” Thick 7 gage
You would commonly see a 3″ x 4″ tongue on larger boats, and boats up to 40 foot in length. Galvanized tubing can look rough, but it is also tough. Not necessarily designed for its fit and finish, but more for its strength and reliability.
