Sam Ashford’s double in the last 10 minutes secured Hemel Hempstead a 2-1 win over the Hawks at Westleigh Park.
Paul Doswell’s side took the lead 10 minutes from time when Danny Kedwell responded from a penalty rebound before Ashford scored twice late on to give the Tudors the win.
Havant had a goal ruled out early on in the second half when Sam Magri was deemed to have fouled in the box as he headed the ball in the back of the net.
There were two changes from last week’s 3-0 win over Hadley in the FA Cup with Josh Taylor and Chris Paul coming into the starting XI.
In a bitty game, which struggled to flow and few guilt edged chances, both sides looked to the middle third as the area to exploit.
There was a long stoppage early on in the game when Mitch Dickenson went down with a head injury.
The first chance by either side in the game came a quarter of an hour in when Danny Kedwell on the edge of the box fed the ball across into Chris Paul but he couldn’t latch on from close range at the back post.
Five minutes later Sam Magri played a long ball over the top into the path of Jonah Ayunga but possession found Boness before the Kenyan International.
Hemel had a spurt in the middle part of the opening period when first Read was caught in possession leaving Ashford in possession before going for goal where Ross Worner stood strong.
The following corner was headed just past the post as the Tudors began pressurising up the other end.
Two minutes later Straker played a long diagonal ball over the top into the path of Ayunga but the Hemel goalkeeper did well to legally knock him off the ball.
Then seconds later the Hawks left back had a go from the edge of the box but his attempt was well blocked by Connor Essam.
In the eight minutes of added time allotted the Hawks had two opportunities to try and break the deadlock.
Firstly, Taylor had a go on the half volley on the edge of the box after the ball inadvertently found him, but the effort blocked by Sterling.
That before Ayunga turned on the ball in the box before dragging his effort wide of goal.
HALF-TIME: Hawks 0-0 Hemel Hempstead Town
Havant came out the traps flying at the start of the second half.
Three minutes after the restart a Josh Taylor throw found Danny Kedwell at the near post who flicked the ball across goal but held by Boness.
Seconds later the Hawks had the ball in the back of the net but for the goal to be ruled out for an infringement. Drury down the right flank floated a brilliant ball across the box into Sam Magri at the back post who rose highest to nestle the ball into the bottom right corner, but the goal was ruled out for an infringement on a Hemel defender.
Determined not to make that goal define the game, the Hawks continued to burst forward to try and get that opener.
Chris Paul slipped in Andy Drury but he couldn’t get his effort away on goal.
A minute later Ayunga had an effort from 12 yards out, but Boness made himself big to deny the Hawks striker.
As the pressure piled on the Hemel defence Benny Read had an effort from distance, his attempt went over the bar.
Just before the hour mark Connor Essam for the Tudors was the one that had to be alert as the Havant onslaught continued. This time Read turned provider after playing a ball in down the right side before before knocking the ball away with Kedwell lurking from close range ready to pounce.
Havant had another spell with just over a quarter of an hour to play when just after Alfie Rutherford was introduced to proceedings he stayed on the feet following a challenge and had a go on goal from just outside the box, but the wet surface took the sting out the effort as it comfortably found Boness.
Seconds later it was Jake Flannigan, who replaced Chris Paul five minutes earlier, who who slipped the ball through to Jonah Ayunga who with the Hemel ‘keeper out elected to chip the ball but again, agonisingly, it trickled past the post.
With just over ten minutes to play the Hawks won a penalty when Alfie Rutherford was bundled to the deck by the Hemel ‘keeper Boness.
Danny Kedwell stepped up before he saw his penalty saved, but the ball fell straight back to him before rifling home from two yards out, not needing to be asked twice.
But three minutes later the Tudors equalised when Ashford was allowed to turn in the area before firing the ball home to level the scores.
Looking for an immediate reaction and get their noses back in front, Bailey floated an exquisite free kick into Rutherford who’s header was spilt but no one could get on the end of it and pounce.
In the first of four added minutes at the end of the second period Ross Worner thought that he had made a vital save to preserve a point when Ashford found himself one-on-one with the Hawks ‘keeper before making himself big and pulling out a big save to keep it level.
But with virtually the last kick of the game Hemel went on to win the game when Ashford again was allowed in space from close range before hammering the ball home to give Sammy Moore’s side the three points.
