What makes a pontoon sink?

A pontoon can sink due to several factors, including water intrusion from leaks or damage to the pontoons, overloading beyond its weight capacity, or improper weight distribution. Additionally, structural failures or the failure of components like the transom can lead to instability. Environmental factors, such as rough waters or extreme weather conditions, may also contribute to a pontoon sinking if not properly managed. Regular maintenance and inspections are essential to prevent these issues.
