The sports club enjoyed their greatest success in the 1970s and 1980s when the team spent seven seasons in the third tier.

Since being reformed and winning promotion in 2010,[2] Portowiec have faced financial issues to run the club.

Having played in the regional leagues for most of their history, Portowiec's rivalries have been teams from the Gdańsk area, and as a result games involving the Gdańsk Derby.

In the early years of their formation, Portowiec had a minor rivalry with the city's giants, Lechia Gdańsk, facing them seven times between 1970–83.

Alongside football Portowiec has a section for yachting.
