Douglas produced one of the results of the season to stay second in South Lancashire/Cheshire Division One on Saturday.
Bryn Snellgrove led the way with two tries and four conversions as they won 43-7 at Sefton in an impressive display.
Craig Magee, Luke Hyland, Lance Wylie and Carl Markl-Ferns went over for the other Douglas tries.
There was disappointment for Vagabonds in Division Two though, as they lost 15-0 at home to Bowdon.
Ramsey were also beaten at Southport who now overtake Vagas to move into fifth place.
An Ali Trace try, converted by Dan Bonwick, was the northerners’ only bright spot.
