Amsterdam - A Dutch civil youth court appointed a temporary custodian for 13-year-old Laura Dekker who wants to solo-sail the world.

During the next two months, a court-appointed psychologist is to investigate whether the teenager's trip around the world could harm her emotional, social and physical development - as charged by the youth protection services.

The psychologist is also to assess Laura's capabilities to deal with the challenges she would face during her two-year-long voyage.

But the court rejected the youth protection services' request to suspend altogether her parent's custodial rights.

The civil youth judge emphasized the parent's approach towards Laura and her sailing plans did not meet the requirements to take what it said was "the most extreme measure."

The court also rejected the youth protection services' request to place Laura in the care of her mother or in a youth facility pending further investigation.

Dekker's parents formally requested the local authorities several months ago to permit their daughter to miss school for two years so she could undertake her solo voyage.

When permission was denied and the parents announced they would still support their daughter's plans to sail solo around the world, youth protection services launched an investigation and eventually filed a suit in an emergency procedure.

Laura Dekker lives with her father on his boat near Wijk bij Duurstede in the central Netherlands. She has Dutch, German and New Zealand nationality. (dpa)
