Abstract: A watercraft trailer has a releasable connector for releasably connecting a watercraft to the trailer. The releasable connector has a lever pivotally connected to a connector support and a hook connected to the lever. Pivoting of the lever towards a front of the trailer moves the releasable connector to a locked position and pivots the hook towards the front of the trailer. A locking mechanism prevents the releasable connector from moving to an unlocked position by applying forces to any one of the lever and the hook that would otherwise pivot the lever and the hook towards a rear of the trailer. Unlocking the locking mechanism moves the releasable connector to the unlocked position and pivots the hook towards the rear of the trailer. A method of securing a watercraft to a watercraft trailer and a method of releasing a watercraft from a watercraft trailer are also disclosed.
