The hatches on the rear lockers are only held in place with a piece of rope that is fastened from within the cabin. Many other owners have added hinges to improve these hatches. This seems an easy job but like all things it takes a little longer than planned. Some of the bolts need to be carefully shortened so they don't rub on the edge locker, also it may be necessary to remove the polystyrene blocks so you can get easier access to fit the nuts on the underside. Currently I'll continue to use the rope system to hold the hatches down but will explore different catches to make an even more secure solution.
