Despite his attempts he did not recover ships taken by Swedes in Wismar and Travemuende. Władysław decided to build a new fleet and created a "Naval Commission" with Gerard Denhoff as a chairman to fulfill this task. The choice of other members of this Commission was not random, it contained wealthy king supporters, like the merchant and owner of a merchant fleet from Danzig, Georg Hewel (Gdańsk, Jerzy Hewel). Because the Sejm (Polish Diet) was at best reluctant to pay for new ships and royal chest was permanently empty it was due to Hewel that the new fleet was created at all. He gave to the king's disposal 10 ships, a few of them were carrying small caliber cannons. These ships had to be modernized in order to allow them to carry heavier cannons. Additionally the king wanted to build a few galleons in Danzig and Puck and because of long construction times, also to purchase a few ships abroad, but those plans were not realized (except of purchase of one Danish ship - requiring quite serious repair).
