Havant produced a ruthless display to inflict a 104-7 defeat on Dover in London one south.
The hosts ran in 16 tries in a one-sided affair at Hooks Lan.
‘We think it is our highest ever score in the league,’ said head coach Will Knight.
‘To score more than 100 points is huge and from that point of view it was a satisfying game.
‘We have talked with the players about being professional enough to score points when they are on offer.
‘That is exactly what they did in this game.
‘It isn’t always easy playing in games like this because they lack a lot of structure.
‘You have to feel a bit for Dover, who are having a tough time of it.
‘However, we maintained our discipline and concentration to keep it going right through.’
The home side led 42-0 at the halfway stage and went on to add 100 more tries in the second period.
Loz Blackburn (three), Joel Knight (two), Scott Morris (two), Tristan Trehan (two) Jerome Rudder, Jerome Trail, Mitch Goldring, Dave Sweeney, Ben Brierley, Gav Hart and Jack Ward Golden all got on the scoresheet.
United Services remain in the bottom three of London three south west after a 59-10 defeat at Farnham.
Southsea Nomads captain Ben Horrod was hugely disappointed by his side’s 22-3 defeat at Southampton in Hampshire League division two.
It was a first win of the season for the hosts.
‘We were never at the races and they capitalised on that,’ said Horrod.
‘The players have been putting in the time at training but our game didn’t come together.
‘Our forwards dominated against a much bigger pack.
‘The problem was our inability to attack out wide.
‘This is five points dropped but feel we can improve on it.’
Nomads spent most of the first half on the defensive but still only trailed 8-3.
Jonathan Branston scored the only Nomads points with a penalty.
Player coach Mike Westall was the pick of the Nomads players because of his work-rate around the pitch.
