A father and son were killed last week when a boat sponsored by Heart of Sailing Foundation, an non profit that provides sailing experiences for special needs children and adults. Chao Chen and Jun Chen drowned and either others were injured when the boat capsized.
The boat, initially reported to be a 35-foot rental, ran into unknown trouble shortly after 5 p.m. near Harbor Island. It was not immediately clear why the boat overturned, said Marguerite Elicone, a spokeswoman for the San Diego Port Authority, which oversees the Harbor Police, the agency investigating the accident.

Investigators have not yet determined the cause of the accident. Two possible causes are an overloaded boat or wind gusts. [Source]
