I only use my pontoon boat on lakes, I figure the rivers are for drift boats and rigid framed rafts. I have two mushroom style lead anchors, each attached to 30 feet of parachute cord. I have tied loops in the cord every 5 feet. On my pontoon boat, I have clipped two small spring loaded carabineers. I release one of my anchors at a 45 degree angle to the rear and when it hits bottom I slide the boat over in the other direction, then release the other anchor. I place the boat in the center of the two anchors and clip the nearest loop onto the carabineers. Works like a champ and really holds even in the very stron eastern WA winds.
