The Coast Guard cutter Gallatin is back home in Charleston after 100 days of missions that included seizing more than 2 tons of cocaine and 3.5 tons of marijuana worth about $37.4 million on the wholesale market.

The cutter returned Sunday after missions that included drug seizures, search and rescue, maritime exercises and community outreach, the Coast Guard said Thursday.

The crew also rescued the passengers of a sinking small fishing boat March 15. The survivors were transferred to the Colombian navy.

During port calls, the crew was involved in several community-outreach projects, including ship tours for more than 400 schoolchildren and their teachers in Guantanamo Bay and Roatan. The crew also did painting, plumbing and electrical work in local hospitals and churches.

“This has been a highly productive and eventful patrol, and I’m extremely proud of the crew’s performance,” Capt. Caleb Corson, the Gallatin’s commanding officer, said in a statement.

The Gallatin is a 378-foot, high-endurance cutter with a crew of about 170. It’s the largest and most capable Coast Guard vessel patrolling the Caribbean Sea.
