<p>The present disclosure relates to a boat trailer that is used when a leisure boat is towed by a car to be moved to the water or a storage place and, more particularly, to a boat trailer that allows a tow vehicle to achieve a safe movement to the water without falling into the beach or the seawater. According to the present invention, a rotating tire is disposed on a front surface of the boat trailer. The tire is lowered and moved in a case where the boat is to be moved to the water or be lifted. Accordingly, the boat trailer can be prevented from being stuck in sand. In addition, according to the present invention, the length of a tow frame is increased by a length adjustment device of the tow frame in a case where the boat is to be moved to the water or be lifted. Accordingly, the tow vehicle can be prevented from corroding wetted by seawater. A shock absorbing spring is built into the length adjustment device of the tow frame, and thus a sudden rearward movement of the boat trailer can be prevented and an accident can be prevented.</p> |
