Answer:
Flat bottomed two chined hull
Step-by-step explanation:
For a boat to be used in ponds, small lakes and calm rivers, flat bottomed and two chined hull are perfect. As this type of hull allows them to be used in pond's shallow water. Since the depth is not that much having such type of hull prevents grounding of the boat. Also, this type of hull makes the boat stable in calm water in comparison to a boat with v-shaped or rounded hull.
