  • Davit cradle lift for small boats
    Patent number: 9308971
    Abstract: A davit lift for small boats can be pivotally coupled to a rearwardly projecting horizontal surface of a boat. The davit lift includes a cradle formed of multiple tubular members arranged to support a small boat. Apertures formed in one end of the tubular members are alignable with apertures in a pair of mounting brackets affixable to a boat to receive lock pins. Selective engagement and disengagement of the lock pins allows the cradle to be pivoted from its deployed position, an upright storage position and a forward inclined transport position.
