I am having trouble accounting for Jan Duijm in early 1653

Jan Duijm appears twice in early 1653. On 15 January 1653, his ship was one of four Zeeland warships convoying some merchantmen and West Indiamen from "the islands". The four ships included the ships of Joannes Michielszoon, Claes Janszoon, Cornelis Mangelaer, and Jan Duijm. At the Three Days Battle (or Battle of Portland), his ship towed Michiel De Ruyter's flagship for the last two days or more of the battle. Jan Duijm reappeared in 1658, at the Battle of the Sound. One possible candidate ship is the Sint Jan (26 guns), commanded by Laurens Pensier in the summer of 1652. Another might be the Wapen van Zwieten, commanded by Jan Sichelszoon in August 1652, as well. Without more information, we are just guessing. Sources:
