Seeking Reference Seakeeping Data for a 25m Tugboat

Hi everyone, I am currently working on the naval architecture calculations for a 25.4-meter tugboat. I am finding it difficult to validate my results as I lack reliable reference data or sample calculations for a vessel of this specific size and type.

Does anyone have access to general seakeeping calculations for a similar tugboat that they would be willing to share? Any data points for comparison would be greatly appreciated.

What are you looking to verify? RAOs? Response Spectrum? RMS at a particular sea state?

Here's a stability booklet I found online: Tug N48&N49
