National Two North side Harrogate were entirely dominant in the first half and cruised into a 23-3 lead at the break.
Brothers Sam and Jake Brady both capitalised on influential play from fly-half Callum Irvine to cross the whitewash, whilst Lewis Minikin added five goal kicks.
Tigers, champions in National Three North this season, were unable to break into ‘Gate’s 22 throughout the first half.
And any hope of a second half comeback was blunted by an early Minikin penalty before Willem Enslin touched down at the base of a powerful Harrogate drive.
Minikin capped off an impeccable display by the holders with a classy converted try in the final minute as Harrogate secured the cup for an 11th time.
