A submarine-shaped rocker built for a child who has only just learned to sit unaided. The seat sits 4-in off the floor, measures 11.5-in across and has a 5-in backrest behind it, while a front handlebar gives both hands somewhere to grip. Side rails frame the seat on each flank. A rocking range limiter caps how far the hull can travel, which is the part that keeps a one-year-old from tipping over backward. A propeller on the tail spins a full 360 degrees between rides. The 11-lb basswood ply and MDF body carries 45 lb and meets ASTM and CPSIA standards.
