Summary:
Catamaran: Roughly 1232 Watts to go 80km/h. Easy to manufactureMay be hard to design a chassis for, hard to design mechanical system.
Bullet: Roughly 2235 Watts to go 80km/h. Harder to manufacture, much Much more room for mechanical system.
...
Visually good airflow with turbulence slowing the flow down to 14m/s.
At 22.2m/s there was 55.526N of air resistance requiring [55.526(m^2/s)x22.2(m/s)] 1232.68 Watts of energy to maintain it’s speed.
...
More turbulence with this design
At 22.2m/s there was 107.327N of air resistance requiring [100.7(m^2/s)x22.2(m/s)] 2235.66 Watts of energy to maintain it’s speed.
