There are several differences between heavy-duty and shallow-water models. Heavy-duty models are designed to handle rougher waters, while shallow-water models are specifically crafted for use in more delicate conditions. Heavy-duty boats often have a reverse chine hull design that allows them to quickly cut through the water and provide better stability in rough conditions. Conversely, shallow water boats typically have a shallower draft to navigate areas with less depth. Finally, while jet engines power both boats, heavy-duty models usually have more powerful motors that can handle rougher terrain.
