A boat trailer having a frame with a forwardly extending tongue and a paddle cradle for a boat hull has a pair of longitudinally disposed arms pivotally hinged forwardly to each side element of the frame. Each independently pivoted arm includes a float attached at its rearwardly extending distal end. An outrigger guide arm is attached to the distal end of each arm and extends outwardly and upwardly such that the floats cause each guide arm to extend above the water level during launching and recovery of a boat. A line attached to a boat bow fed over a post and hook on the tongue and aft to a slot in a guide arm permits launching and recovery of a boat by one person.
