You mentioned that you have used this to desing an actual

I can mention one hydrofoil of that type built. It is called 

 Bafun in Russian. All the details of the construction of this vessel 

 were published in our suipbuilding magazine earlier this year, so 

 you can find that. It is the largest vessel with 'Z' -drive in the Soviet 

 Union.
