All professional fisherman “drive on“ to their boat trailers. This is because they know the dangers and challenges of trying to manually handle boats onto trailers against the tide and wind on potentially slippery ramps. They also want no part in the physical exertion involved in doing so. Furthermore, powering onto your trailer is a huge time-saver.
One professional fisherman commented to us “Would you arrive in your car at the garage door, and then manually pull it in the remainder of the way with a cable? NO. We always drive on”.
