Romsey had the rub of the green on the day, in a match where they only had the bare 11 players in windswept Dorset.
In an even opening 20 minutes Romsey pushed in to the Swanage circle, Barry Hatch mistimed his shot, and Sean Rawles and Colin Harwood likewise missed chances.
As Swanage broke it was Simeon Field, Lukasz Suleja and Duncan Sanders who provided solid defence for Romsey to push further up, with young Will Payne covering left back and left half in his man of the match performance.
Romsey broke the deadlock when Colin Harwood ran from the 23 yard line directly in to the circle, forcing a fine save from the keeper, only for Stan Cazaly to recover the ball and square it back for Harwood to slot at the near post.
Romsey doubles their lead with a fine penalty corner routine, Rawles played the ball to Harwood who waited and then played it back to the near post for Rawles to rifle in from a tight angle.
2 0 at HT, and Romsey were tiring, and had to absorb pressure at the start of the second half. Nick Welby in goal was called to leave a Swanage ball from outside the circle it hit the post and rolled in to the goal before a Swanage stick could touch it, and Welby made a fine save at his near post to keep out a fierce shot, before another shot was deflected by Payne on to the post high up and the ball bounced off to the far side of the pitch.
Romsey then took advantage of gaps in the Swanage defence, Harwood following up in the circle pushed the ball in for 3 0, and then a fantastic move from the left side from Harwood senior to Harwood junior, to James Tower, saw the ball played out to Stan Cazaly on the right. He played it in to Sean Rawles for 4 0.
Rawles then got his hat tick following up from a penalty corner routine, and Harwood senior got his from close range for 6 0.
Harwood then hit his fourth from another Cazaly assist, and then Tower, Rawles and Cazaly set up Barry Hatch to touch in for 8 0, and his first goal for the Club which hit the loudest cheer of the afternoon.
There was still time for Swange to create a wonderful move, cutting through the Romsey midfield and defence only for Welby to pull off a fantastic save to keep a clean sheet.
The scoreline was not reflective of a closer encounter, but keeps Romsey top of the league, and now travel to second place Isle of Wight in two week time.
