This data record tells the program to use linear wave as incident wave instead of the Stokes second order wave which is used by default in the calculation of the Froude-Krylov forces. Note that if the LSTF option is used in the OPTIONS data category, the linear wave and the Stokes second order wave will give the same results.

This data record is not recommended for big waves.
