This may come off as a wussie kind of question...but here goes. Anyone rig a small bimini top to their pontoon/cataraft/raft? Or does anyone use an umbrella for days when it is scorching or to ride out a brief downpour? Anybody find a way to mount an umbrella? I'm thinking about adding one to my cataraft, but would like to see how someone else has addressed this. Thanks.
