REEDEREI GERDES GRUPPE.

The source calls this “version 2”, documented on Gerhard G’s port side on 20 July 2013 and Ulrike G’s starboard side; Ulrike G has a narrow black top.

Apparently the more commonly used design, this appears on Dette G to port and Christina G to starboard without a funnel top. Helene G instead has a blue top matching the G.
