Loaded for cruising,dink in the cockpit along with cooler dink motor, barbecue up on the radar arch, full of fuel and water. Lot's of fixed docks with pilings, some make up a fender board made out of 5'or 6' PVC pipe with a line out of both ends so the PVC pipe hangs outside of the bumpers and is against the pilings. I use big bumpers with a line running thru it and knots on either side of the bumper to prevent it from sliding on the line. I tie the line off at both ends to the roof's grab rail and keep the bumper horizontal centered on the piling
