My pirogues tend to paddle best with the nose up. Maybe only a couple inches of the bottom at the bow out of the water. If a head wind kicks up lowering the bow seems to help.
The little punt I made previous to this boat had issues at both ends. Pushing too much water at the bow and dragging too much at the stern.
Pointed stems do separate and put the water back together well, but that is only one requirement of a boat's design. Pointed boats are popular because "ease of paddling" is a priority for most folks. A chaland was only paddled across the bayou and back. Capacity, stability, and ease of building were more important. Variations occurred depending on the builder, materials, and/or particular intended usage. Mine is a variation.
