Lowering the stone into the hold of the boat would have been an interesting process ...

With the arrangement of two logs above the stone and two beneath as in our 2005 stonerowing experiment (see www.stonehengetheanswer.com ) click on 2005 experiment, levers can lift the upper logs and the stone can be lowered into the boat without the levers fouling the gunwhales.
