A father accused of motoring away on a yacht stolen in Alameda with his two young kids aboard, claiming it was to protect them from abuse, faces jail time after pleading no contest to child abduction charges.

Christopher Maffei, 43, could get a maximum of four years four months behind bars for the September odyssey that ended with him surrendering to the Coast Guard with the toddlers unhurt. He entered his pleas to possessing a stolen boat and two counts of child abduction April 19 in San Mateo County Superior Court.

Maffei allegedly snatched his son and daughter, then 3 and 2 years old, from his former girlfriend's South San Francisco home. Prosecutors said he then loaded his children, diapers and food onto the 41-foot yacht Unleashed, which was docked at the Ballena Isle Marina. What his plan was from there remains unclear. But he motored the boat into the Pacific Ocean and eventually ran out of gas.

A fisherman spotted the boat about 50 miles off the San Mateo County coast and called in the sighting to authorities, who later found the yacht and guided it to land.

Maffei and the children, who were OK, had been on the run for about four days.

Prosecutors and the children's mother denied the kids had been abused and no charges ever came from his accusations.

Maffei remains behind bars in lieu of $500,000 bail. He is due to be sentenced June 7.
