Everyone has different strength levels so this will vary per user. To make lifting your kayak with the KayaArms easier we have three main recommendations.

A jig for lifting the chain can easily be made to allow you to use both hands to lift from a neutral position (not bent over) and is described in the videos below. Although it is still a manual lift, lifting from a neutral position with two hands will make it easier.
Below is a video of how a customer uses a jig to lift her Hobie Eclipse Pedal Board with two KayaArms.
