Fidelity IV became a curiosity for tourists as it sat stranded on Gooch's Beach at low tide on Monday. Hours later, his staff moved the boat to its dock in Kennebunkport.
Bush spokesman Jim Appleby says the former president and some family members were aboard when the boat ran aground between 3 p.m. and 3:30 p.m. No one was hurt.
Appleby says Bush was close to shore in low visibility when a wave pushed his boat onto the beach. As water receded at low tide, tourists walked up and snapped photos of the 38-foot boat.
