The hard hitting opener topped the divisional batting charts with 678 runs, having enjoyed a phenomenal run last July.
Twice he missed out in the nervous nineties, with 96 against South Wilts IV and 94 off the Godshill attack.
But, after hitting an unbeaten 58 in the win over Paultons, Gilbert struck the magical century with 113 not out against Amport II. In all, he made 361 runs in four innings in July.
Gilbert, a HCL award winner for the first time, also hit half-centuries against Winterbourne, Amesbury and Andover.
