The accomodations of boat trailers to straked hulls has posed continual difficulty in the boat trailer industry. The longitudinal protrusion of the strakes assists in lifting the hull and trap air beneath their surfaces to reduce the frictional drag on the hull exterior. The strakes and hull design remain substantially constant throughout the remainder of the hull to the transom. Such strakes begin near the bow of the boat and spread transversely along the hull to a location approximately one-half the length of the hull.

To overcome the tendency of such hulls to plow into water, longitudinal protruding ribs or strakes are molded along the hull exterior. The development of molded boat hulls, constructed of glass fiber reinforced resins has tended toward the hull configuration known generally as a "deep-V" hull. The assembly as set out in claim 3 wherein said bearing means is transversely adjustable relative to the bracket on which it is mounted, whereby the location of the pivotal connection of the bracket to a supporting member may be selectively varied along the length of the bracket. The assembly as set out in claim 3 wherein the rollers are rotatably journalled on the axle ends by bearings within the roller structure, the outer end of the axle being recessed inwardly of the outer end of each roller.Ħ. The assembly as set out in claim 3 wherein the outer surfaces of said rollers and axle are formed from hard rubber material.ĥ.
