The carrier includes a cradle having an elongated spine and a number of ribs which are spaced along the length of the spine. The spine is pivotally attached to a larger boat such that an end of the spine may be raised or lowered. When the end of the spine has reached its lowermost extent, it is immersed in water and allows a smaller boat to be floated into the cradle. When the end of the spine is raised to its uppermost extent, the smaller boat is lifted entirely out of water. A hoist or actuator serves to raise and lower the end .
