St Catherine's College Boat Club Oxford

Well This is the newer version of the Boat Club's Coat of Arms. I say newer, neither have been ratified by the college of arms, making there use unofficial. I've tweaked the gules in this one to better match the one I see in common use and the bend I've used the obscure in heraldry, though regonised by the boat club, Bleu Celeste. I shouldn't really try to ratify this one too much, as unlike the college ones this is far far more coloquial.

If I had to blazon this myself I'd probably go as follows
