Default Issues adding k-omega turbulence to a solitary wave

Hi,
I am trying to recreate a paper which simulated a wave tank with a solitary wave, with k-omega sst turbulence.
I started with the OpenFOAM example waveMakerSolitary, changed it from 2D to 3D, and the wave looked reasonable, and not too different to the paper I am trying to recreate (see graph 1 in link below).
However, when I turned on the k-w sst turbulence, the wave started moving really slowly (see graph 2 in link below). I'm assuming that I have made an error somewhere when turning the turbulence on, potentially when adding in the k, nut, omega files in 0.orig, or when editing the fvSchemes/fvSolution files, but I can't seem to work out how to fix it.
I've tried changing the solvers, the discretization schemes, time schemes, mesh resolution etc but it still doesn't look right.
I would be grateful if someone could work out where I'm going wrong. Thank you!
