  • Patent number: 11661128
    Abstract: A dolly for a water vessel is an apparatus that facilitates the transportation of a water vessel on land. The apparatus serves as a universal attachment for water vessels. The apparatus includes left brace assembly, a right brace assembly, a connector bar, a first roller assembly, and a second roller assembly. The left brace assembly and the right brace assembly attach onto a transom of a water vessel. The left brace assembly and the right brace assembly may be adjusted to accommodate transoms of varying heights. The connector bar mounts the left brace assembly with the right brace assembly, thereby positioning the first roller assembly and the second roller assembly. The first roller assembly and the second roller assembly uplift the water vessel and rolls the water vessel across the ground. The apparatus further includes a cradle mechanism which further supports a paddleboard or a kayak.
