In a situation where you don't totally load the holds of your kayak, does the loose load cause problems shifting in rough water or if you do a roll? It strikes me that it would make sense to secure items in the hold of my Tempest 170 so that the storage items act as ballast and don't rotate to the deck side during a roll or edging turn. I am thinking fixtures glued to the inside of the hull and then use bungie cords to tie down the load. Alternately, I thought about putting an inflatable beach ball in the hatches and inflating those so the load doesn't shift. Do folks do this? Thoughts? ...or do you even worry about that?
