The U.S. Coast Guard seized nearly six pounds of marijuana and more than nine ounces of hashish from a boat that was sailing erratically in the Mare Island Strait in Vallejo Thursday evening.
A 53-year-old man on board the 35-foot vessel was taken into custody for possession of narcotics and turned over to Vallejo police, the Coast Guard said.
A large tanker vessel informed Coast Guard Station Vallejo around 7:30 p.m. Thursday about a vessel sailing erratically in the shipping channel near the Carquinez Bridge, the Coast Guard said.
The Coast Guard dispatched one of its 25-foot response boats and the crew located the sailing vessel driving in tight circles at the entrance of Mare Island Strait, the Coast Guard said.
When Coast Guard personnel boarded the boat the operator indicated he had approximately six pounds of marijuana on board, the Coast Guard said.
A search of the vessel revealed several one-gallon zip-lock bags of a green leafy substance that tested positive for tetrahydrocannabinol, THC, the Coast Guard said.
The boat was then moored in Vallejo. Vallejo police were not immediately available for information about the vessel operator.
