Abstract of the Disclosure A boat trailer frame is described including an adjustable pair of elongated frame members extending from a tongue section to a wheel supported carriage. Bunks are mounted directly to the frame members. Forward ends of the frame members are pivotably mounted to the tongue and selectively clamped to the wheel carriage. Lateral adjustment of the distance between the frame members and bunks is provided to accommodate boat hulls of varying configurations. Such lateral adjustment is accomplished simply by pivoting the frame members together or apart about the forward pivots at the tongue. Clamps are included for selectively securing the frame members to the carriage assembly and tongue once a selected space between the bunks is achieved. Other clamps are used to facilitate longitudinal adjustment of the wheel carriage position along the frame members to adjust "tongue weight".
