Based in Portland, Maine, the team plays their home games at Cross Insurance Arena.

[6] By March 8, the arena owners had narrowed their choices to the proposals submitted by Spectra and National Sports Services, with both groups having been involved with managing ECHL teams in their past.

[7] In June 2017, Comcast Spectacor, Spectra's parent company and the operators of the Cross Insurance Arena and the NHL's Philadelphia Flyers – the founders and NHL affiliate for years of the original Maine Mariners AHL franchise in Portland – purchased the franchise rights of the recently dormant Alaska Aces of the ECHL.

[8] Philadelphia Flyers president Paul Holmgren will serve as the team's governor with former player Danny Briere overseeing the day-to-day operations.

[23] In the 23-24 season, because of the termination of the Newfoundland Growlers's franchise rights with a couple of games to go, ruining the scheduling, the ECHL announced that they would base the divisional standings (for the North only) on point percentage, keeping the top four teams into the playoffs.
