With the three sides above them in the RBS National League all out of action due to the weather, Dundee High took the chance to close the gap on Stewarts Melville, Watsonians and leaders Boroughmuir.
With the match switched from a waterlogged Braidholm to merely sodden Auldhouse, Dundee made light of the conditions for a convincing win with four tries ensuring the bonus.
GHA were under pressure from the start and after nine minutes Tim McKavanagh’s offload put Bryce Hosie in for the opener. Hosie missed the conversion, as he did with the next one after Steven Longwell rumbled over from a line-out drive but a couple of minutes later he made no mistake with a penalty to take Dundee 13-0 ahead.
The home pack found themselves in serious trouble at a scrum close to their line so when Andy Dymock finally fed Hosie, the No10 had only to skip through for the try and conversion.
Try number four was a replica of the second, even down to the scorer, as Longwell again applied the coup de grace from a line-out drive and with a few minutes of the half remaining a Hosie penalty took the score to 30-0, his tally for the match to 20 and his total for the season nudging on a splendid 250 points.
The scoreless second half was notable mainly for an odd spell when High were penalised 10 times in 15 minutes, picked up two yellow cards and saw Hamish Livingston go off with a leg injury.
Despite their numerical advantage, GHA were unable to turn things to their advantage.
