Macclesfield Town drew for the fourth time in five games and again will see it as two points dropped after failing to hit the net against a Grimsby side second from bottom of League Two.
Both sides hit the woodwork with Emile Sinclair and Matthew Tipton both squandering glaring chances as once again the Silkmen forwards misfired.
Macc won a free kick in the very first minute after a swift move down the left which was lashed high and wide by Hamza Bencherif.
The visitors had a free kick in a dangerous spot themselves early on and went a little closer, with Peter Sweeney's 25 yard effort forcing Jon Brain into a good stop to palm around the post.
The Mariners looked the better side in the opening quarter of an hour and had the ball in the net through Jean-Louis Akpa Akpro when he bundled in Ben Wright's low cross but the referee blew for a foul.
Michael Leary shot straight at Brain from long range and minutes later Sweeney also found the arms of the keeper with a volley from outside the box as the majority of the play was in the Macc half.
The Silkmen failed to make any inroads until the 23rd minute when the tireless Lee Bell's free kick was deflected behind by the wall and then his corner was met by a powerful Nat Brown header which flew just over.
Soon after Sinclair should have opened the scoring when Ross Draper pulled the ball across the face of goal and at the far post he somehow failed to turn it in from close range.
From the resulting corner Bencherif met Bell's centre with a thumping header which keeper Nick Colgan had to dive back to just about stop before it crossed the line.
Macc looked more and more dangerous as the half wore on and went within inches of breaking the deadlock when Colin Daniel curled a 20 yard free kick around the wall which beat the keeper but came back off the post.
Colin Daniel - Came closest with his free kick and had a frustrating afternoon
On 37 minutes the visitors struck the woodwork courtesy of Michael Coulson's rasping 25 yard drive which was brilliantly tipped onto the bar by the fingertips of Brain who then had to swiftly get to his feet to catch the ball as it dropped in the goalmouth.
Somehow there still no goals as the sides went in at the break, with Macc's superiority growing by the minute and they kept the pressure on early in the second period with Sinclair's cross shot well saved by Colgan and Draper forcing a corner with a strong run down the left.
Casual defending nearly allowed Akpa Akpro to capitalise when Shaun Brisley wasn't expecting Nat Brown's pass along the back and the forward stole the ball from him and fortunately for Macc placed his shot wide as Brain charged out to close him down.
Dazzling footwork from Colin Daniel allowed him to skip past three challenges and give Bencherif a chance to cross the ball back to him but he could only head straight at the keeper at the near post.

The home fans were becoming ever more frustrated as Macc created numerous chances without putting one away and Ricky Sappleton was introduced for Ben Wright midway through the half.
Coulson almost caught Brain cold with a shot out of the blue following a throw on the Mariners left wing but the former Port Vale keeper was down quickly to push it round his near post.
The chance gave the visitors a bit more impetus to go forward and they almost found the vital goal when substitute Adam Proudlock's effort cannoned back off the foot of the post and Jamie Clarke wildly hammered the rebound over.
With five minutes to go it was head in hands time again for the home fans when Sappleton was released down the right to slide the ball across goal, just out of Bencherif's reach and wastefully smashed over from close range by Tipton.
The Silkmen yet again went close in the closing minutes as Bencherif played Sappleton through and the drive from the loanee striker beat the keeper but bounced agonizingly the wrong side of the post.
Both sides hit long balls hopefully into the box in the final stages and the four minutes of time added on but despite so much goalmouth action there was to be no late winner with a point doing little for either side in the League Two standings.
