There was an impressive haul from the wingers who managed to run in six of the eight tries. In a first half containing some superb handling and unstoppable pace, James Ellar grabbed the first two, followed quickly by a brace from his wing partner Simon Frewin who ended up with a total of four tries, including three from long-range.
Full-back Tom Coad also weighed in with two tries, one in either half, leaving fly-half Greg Wood to mop-up the remaining 11 points with four conversions and a penalty.
Waterloo had more possession in the second half but they rarely looked like finding their way through the home side’s well organised rearguard.
Tries were not in short supply for Harrogate as well, who ran out comprehensive 54-5 winners over Lymm.
Aarin Yorke’s pace took him clear for another try for the home side – again converted by the impressive Irvine – before Sam Bottomley and Oli Denton both went over.
James Audley-Beck then went over the line, with Irvine on hand to stick the ball between the posts once more, giving the home side a healthy and commanding 33-0 lead at the break.
The scoring continued in a similar vein after the break. Jimmy Brown was first to go over before Lymm broke free through Joe Knowles and, in a rare attack, he sped clear to go over the line for what was their only score of the game.
The game’s final score came from substitute back, Mike Aspinall who dummied his way through for another fine converted try.
There was also a 50-point haul for Yorkshire’s other team in the division, Bradford & Bingley picking up a welcome 52-27 win against bottom club West Hartlepool.
It saw the West Yorkshire club go 12 points clear of third-bottom Birkenhead Park, who went down 22-13 at second-bottom Kendal.
