Boat Cheat Code in GTA: Vice City Stories (PSP)? No Specific Boat Cheat Exists

No cheat spawns a boat specifically. The "Spawn Vehicle" cheat randomizes land/air/sea:

R1, R1, L1, R2, Left, Right, Left, Right, Left, Right

Boat chance is low. Reliable methods:

• Docks/marinas: Vice Point, Marina, Leaf Links, Escobar Intl. waterfront – Speeder, Tropic, Dinghy, Coast Guard
• Mission "All Hands on Deck": Unlocks a permanent boat at your safehouse
• Cheat "Cars Drive on Water" (Right, R2, Circle, R1, L2, Square, R1, R2): Drive any car into ocean—turns it into a boat (handling stays car-like)

Explore the map—water coverage is 40%+. Boats are everywhere.
