How to complete the boatyard asset?

"I Understand that The riding boats are little difficult than driving a car and I've Used my mind and I found that it was not a challenge for me." You have no need to ride the boat, before you enter inside the boat and begin the mission just follow these steps. First you have to type the floating cars cheat 'SEAWAYS' so that your car can drive through the water, but make sure that you drive only Hotring Racer Cars because those are the fastest cars in vice city. To Spawn Hotring Racer Cars either type 'GETTHEREVERYFASTINDEED' or 'GETTHEREAMAZINGLYFAST' both includes Hotring Racer Cars, drive till the end of the docks beside boats, take the car a little beyond the boats and get out of the car and get inside the boat, as soon you get in the boat the mission gets started, immediately get off from the boat and jump towards the car and get inside it then get all the packages by car, avoid getting hit towards the walls and other boats.
