Your diagram shows the two bullet-shaped pontoons on each side
arranged nose-to-tail. Why not place them tail-to-tail, butting against
each other, to present a tapered bow and stern to the water? For
that matter, you could add a barrel-shaped third section between
these two, to make the pontoon 10 or 12 feet long.
