For the second season in a row the Vikings humbled Hull - making a mockery of their visitors' title aspirations - but their night was soured by a spate of injuries.
Marquee signing Kevin Brown starred but went off 60 minutes into his debut with an ankle injury, while centre Stefan Marsh dislocated his shoulder and coach Denis Betts said: "Kevin will have a scan and we are looking at it positively and maybe it's just a twisted ankle. But Stefan could be out to 10-12 weeks."
The injuries took the shine off an impressive show with Paddy Flynn and Cameron Phelps scoring two tries each, with the other touchdowns coming from Chris Dean, Frank Winterstein and the outstanding Gareth Hock.
Betts added: "We made a dodgy start but stayed solid. We had to work hard and it's never unexciting coming here. I am happy with the way we defended and Gaz (Hock) is exciting and good for the team.
"He's going to get better but can do things other players can't do. Ben Cross also gives us a bit of punch but I am not satisfied with two wins out of four because we should have beaten St Helens too."
Last season Hull coach Peter Gentle tore into his players after an abject showing at the Stobart Stadium and tonight was no different.
"We are playing without patience and should not have conceded a try just before half time when we led 12-4," he said. "We did not give ourselves a chance with a poor completion rate and too many penalties.
"We have to do a lot better than that. We have made no progress from last year and need to make changes. The personnel out there aren't doing it."
Gentle has injuries of his own to deal with and added: "We need our two key signings Gareth Ellis and Daniel Holdsworth back, but the players out there should have done the job and didn't."
