yes? GO vertical_section
will sample a model output to match a cruise.
As-is, the script uses regularly spaced points along a straight line cruise path, but if you examine (and modify) the internals of the script the same procedure can be used to sample your model at arbitrary cruise stations. Just replace the variables "x_vsect" and "y_vsect"with the actual lon, lat positions of your cruise stations.
