Umberto Robina

Umberto Robina has Tommy and Cubans intercept a Haitian shipment. Tommy takes a Cuban Jetmax out into the bay and sinks every Haitian boat carrying drug crates back to shore.
Naval Engagement is a mission in given to protagonist Tommy Vercetti by Cubans leader Umberto Robina from his father's café in Little Havana, Vice City.
Just like other missions for Umberto, (Stunt Boat Challenge, Cannon Fodder and Trojan Voodoo) this mission can be played at any time even after beating the main story.
Umberto is annoyed that the Haitians forced him to escape during the beginning of the previous mission so he wants Tommy to mess up a Haitian drug deal. The Haitians are having a deal with the Streetwannabe's in a mansion in Starfish Island, so Rico and Tommy approach there in a speedboat to screw up the deal from the water.
Tommy then goes to Viceport, where Rico is waiting on his Cuban Jetmax. Upon getting, Rico and Tommy get into the boat and they drive to the mansion where the deal is going down.
Arriving, Tommy opens fire at the Haitian bodyguards on the Tropic boats, then, the Streetwannabes will turn on the Haitians. They kill the three Haitians conducting the deal and take the coke. Tommy kills all the Haitian bodyguards on the Tropics and then blows one of them up to leave Rico some space where he can drop Tommy off.
Afterwards, the Streetwannabe's, wielding Rugers, soon begin to attack Tommy. Tommy takes cover and guns them down. Some of the Streetwannabe's will be wielding Stubby Shotguns, so the player must be careful not to get too close to the attackers. When they're all dead, pick up the briefcases of drugs that they drop. There are two near the house and one in the alcove where the negotiations were taking place. Once Tommy collects the drugs, two surviving Haitians in a Dinghy blow up Rico's Jetmax. After that, Tommy gets a wanted level. He returns to the café and delivers the drugs to Umberto.
