Maidenhead kicked-off and immediately won a scrum. Quick ball along the line saw Hammond and Ansell punch holes in the Marlow defence to set Guest away for the opening try, which Ward converted.
Marlow responded immediately and their good forward play and caused Maids to concede a penalty, which Marlow kicked.
Maids then mounted a concerted 10-minute attack with several flowing moves, which Marlow defended magnificently. All Maids had to show for their possession was a second Ward penalty.
Just before half-time Marlow broke back with a vengeance, in a looping move from deep in their own half and they were only just kept out by a magnificent Hammond tackle.
Maids won the subsequent lineout and immediately cleared their lines, driving upfield for Ward's third penalty kick and a 13-3 half-time lead.
Maids saved their best play for the second half. With Guest dominating the lineout and their forwards controlling the rucks and mauls, Maids scrumhalf Neill was able to dictate play, launching a series of penetrating attacks.
The first move of the half saw Hammond and Ansell break through, swapping several passes before Ansell scored Maids second try, which Ward converted.
Shortly afterwards, winger Bell burst infield like a battering ram before setting Ward free.
The Maids centre drew two men and set up a try for hooker Bowden who unusually was in close support. Ward converted and followed up with a penalty when the next move broke down.
Maids were unable to add to their tally before Marlow broke clear down the wing for their only try of the game.
Maids closed out the game with a brilliant individual try, Hammond running clean through Marlow's defence from 70 yards for Maids fourth try.
