If you read the output from CPPTRAJ (or ptraj) it will show you that you
selected all atoms for the rms command (i.e. all waters + biomolecules).
This will be a large RMSD. To select a subset, select some atom mask:

rms first mass out pdb_wat_P.rms .P time 0.2

If you need more information on masks, read the CPPTRAJ manual.
