The Sentinel is a unique flying boat built for players who want the fastest possible travel speed. Available from the Luxury Boat Dealer for $1,000, it is one of only two boats capable of flight, making it highly effective for covering long distances across the sea.

Its main advantage is mobility. When traveling away from land, the Sentinel lifts into the air, allowing it to move above the ocean instead of remaining on the water's surface. This makes exploration and island to island travel much quicker than with standard boats. As it approaches land or slows down, it automatically returns to the water, so flight is limited to open-sea travel rather than continuous airborne movement.

The boat is designed purely for solo use, with space for only the driver. While its unmatched speed makes it an excellent personal transport option, players looking to travel with friends or transport a group will need a larger vessel.

Obtainment:

Obtaining the Sentinel requires ownership of the Fast Boats Game Pass. Once the game pass is unlocked, the boat can be purchased from the Luxury Boat Dealer.

Although The Sentinel is the fastest boat in the game, it is not always the fastest way to travel. Players with strong mobility options, such as the Light fruit flight abilities, can often move across the map just as quickly or even faster without needing a boat. Likewise, fruits that allow movement across water, such as Ice or Awakened Magma, can reduce the need for a dedicated vessel.

The Sentinel is most valuable for players who do not have access to flight moves, water walking fruits, or the Shark race's water mobility advantages. In those cases, it serves as an excellent travel option, offering extremely fast movement between islands and making long distance sea travel much more efficient.
