In order to help the Low Countries to gain some extra trade, I would suggest to add some extra trade power:
Antwerpen shouldn't not only have an 'Centre of Trade' but also the 'Scheldt Estuary' modifier and Zeeland could get the 'Meuse Estuary' modifier.
Combined with the existing 'Centre of Trade' and 'Rhine Estuary' of Holland, their coast will be a Trading power house.
