A more thorough explanation:

Definition: Boatable is an adjective that means the same thing as navigable. Navigable means that a body of water is capable of allowing boats or other vehicles to pass through it, making it usable for travel or commerce.

For example, a river that is wide and deep enough for boats to travel through is considered navigable or boatable. On the other hand, a small stream that is too shallow or narrow for boats to pass through is not navigable or boatable.

Another example of a boatable or navigable body of water is a canal. Canals are man-made waterways that are designed specifically for boats to travel through, making them highly boatable or navigable.

Overall, boatable and navigable both refer to bodies of water that are capable of allowing boats or other vehicles to pass through them, making them usable for travel or commerce.
