Carl Stapel says that I am mistaken about the Groninger Nicolaes and Gelderland

Carl Stapel says that the Groninger Nicolaes (or Groninger Sint Nicolaes) and the Gelderland were two separate ships. He says that they both took part in the Battle of the Kentish Knock. Despite the fact that I had seen the page with Laurens Hermansz Degelcamp in command of the Gelderland, I cannot find the photograph, today.
