The Grotti Tropic is a large drivable boat in Grand Theft Auto: Vice City, Grand Theft Auto: San Andreas, Grand Theft Auto: Vice City Stories, Grand Theft Auto IV, GTA: Chinatown Wars and Grand Theft Auto V.
GTA Vice City — GTA Vice City Stories
Earlier iterations of the Tropic prior to GTA IV are essentially flybridge motor yachts or cabin cruisers, evidently featuring living space on the lower compartment of the boat and a partially covered bridge on top; in GTA Vice City and GTA Vice City Stories, a small kitchen is visible from the door in the back, while in GTA San Andreas, the front windows are semi-transparent, allowing the player to see a small living area with red curtains, tables and two sofas. The Tropic in GTA Vice City Stories, however, is sharply reduced in height, with its top chopped and featuring an open flybridge.
It is also one of the boats wanted by the Civil Asset Forfeiture Impound for export in GTA Vice City Stories.
In GTA IV, the Tropic is still a cabin cruiser but has a low-profile cabin housed in its bulky hull and has moderate speed. The boat, however, is distinguishable from other speedboats by its accessories. For any Tropics with an optional spoiler, retractable roofs (front, back, or both) or a glass fairing (front only) may be further attached on the spoiler itself. As the boat is reduced to a size smaller than even the Jetmax or Squalo, the title of largest boat now belongs to the Tug Boat, which is easily twice the size of the pre-GTA IV Tropic. If you jump when in the cabin the roof isn't solid.
The Tropic returns as seen in the Gameplay Trailer. It has a lot of different design from GTA IV. It also has a different spoiler and different paint job.
Despite its size and weight, the Tropic in GTA Vice City has an exceptional top speed, and it is capable of sustaining 130 km/h (81 mph) in calm waters and 100-110 km/h (62-69 mph) in choppy waters, although its ability to turn at high speeds is poor. In GTA Vice City Stories, however, is generally one of the slowest of all boats (in a similar level as the Marquis and Rio) due to its size and weight.
The GTA IV rendition features greatly improved performance, but remains a lower-end speedboat, though it is the third-fastest boat, having a similar speed as the game's Dinghy. For this reason, it is the least commonly used boat in the multiplayer races of GTA IV.
The GTA San Andreas rendition is remarkably fast, comparable to a Squalo, due to the fact it's powered by two large Waterjet engines. It is a great boat for transporting large gangs, and great for just cruising around in the waters of San Andreas. Its only disadvantage is its horrifyingly bad turning. Even at low speeds, you'll need a mile and a half just to turn in this thing!
