It was thought he would sign a two-year contract, with longer term assurances a reason for him turning down the one-year deal offered by City, but it seems that opportunity for first team football is the only reason for the move.
He said: "I got a phone call asking me if I was interested. I was offered a contract at Hull but I wasn't first choice and I thought that I would have more chance of playing if I moved to Grimsby."
The 33-year-old knows all about Division Three football - or League Two as it will be known next season - having been instrumental in a relegation battle, a play-off campaign and a promotion during his time with City.
He had the following advice for his new side: "It is important that we get off to good start. It is important that we get a good run going and keep it going. Our main aim is to at least be challenging for the play-offs. With the new players that are coming in I'm sure that we can do it."
