A useful resource for finding ship records of early German immigrants to Pennsylvania are the books published in three volumes, "Pennsylvania German Pioneers", by Ralph B. Strassburger and William J. Hinke, 1934. (Click here to access the book's index and all three volumes for your own research).
My interest in this book is to locate information about my Reese ancestors. I used the index to find Reeses who arrived at Philadelphia between 1727 and 1808. I found several arriving between 1747 and 1803, and copied snippets of the pages, shown here:

I returned to the index and found one entry for Zerr, as follows, Johan George Zerr, who arrived at Philadelphia from Rotterdam and Cowes in August of 1750:
An image of the port Johann Zerr and many others sailed from, the Harbor of Rotterdam, is shown here:
The Harbor of Cowes on the Isle of Wight is shown here:
