The squallo; is the second fastest boat in the Grand Theft Auto series, being available only in Grand Theft Auto: Vice City, and San Andreas. It is a hard boat to obtain, because both games require the player to complete a set of missions, and Boat School, for Vice City and San Andreas respectively. It is also the fastest boat that looks like a normal type of boat, the faster Jetmax can be obviously categorized into a "custom" boat.
On one mission for Ricardo Diaz in Vice City called "The Fastest Boat" the Squallo is stated as being the fastest boat. This is a factual error as both the internal files and numerous tests by people state that the Jetmax is faster.
