Aerodynamic and Hydrodynamic Performance
design for Powerboats

I found Jim Russell from AeroMarine Research, the software is 'so good', and it helped me very, very much." [Ari Nurminen, Finland, Aug 2021]

Scream and Fly magazine Review of TBDP/VBDP Ver. 8
"...the very best and most comprehensive performance evaluation tool available."

"..Other software such as generic CFD (Computational Fluid Dynamics) analysis software just don't get such meaningful or accurate results!"
