Our Squadron Pennant was designed to incorporate the Peterborough Lift Lock as designed by local artist George Elliott. Upon approval by the CPS Governing Board on recommendation of the Flag & Etiquette Committee, the design was produced. All active and current members of Peterborough Power & Sail Squadron are permitted to fly the Squadron Pennant on their vessels.Annually all new members graduating from the Boating Class receive a Squadron Pennant at the Graduation Ceremonies.
In 2009, upon approval from the CPS National Secretary, on recommendation from the Flag & Etiquette Committee, a gold bar was added to the fly of the Pennant to create a Longevity Pennant to denote the Squadron's 50th Anniversary.

The Squadron later designed a logo with the graphic from the Pennant enclosed in a ship's wheel. It was developed to embroider on various items of clothing.
