Water is a main feature in the game. It covers most of the areas the player floats to. If the player were to touch the river's water, it will damage and eventually kill them. Water that appears when launching the boat will not deal damage unless the player moves on the water outside the building space.
There might be ways to avoid damage dealt by water. Jumping on it may not deal any damage as a bug.
Buying one of the animations will cause to not take any damage at all!
- While water in Build A Boat For Treasure was visually designed to replicate real life water, the Roblox texture used for it is actually sand.
