"Some of the Slovaks tell us that a big boat passed them, going at more than usual speed as she had a double crew on board." (Jonathan Harker's Journal pg. 379)
This quote is important because it is saying that Dracula could be making the boat go faster with some of his powers.
the main point of what we read was about them following Dracula down river and those that they encountered on the way. they devised a plan to sail with a Romanian flag because people thought they were govt officials so people let them on the boat freely to inspect whatever they wanted and ask questions it didn't work they didn't find him and couldn't locate his exact whereabouts but they got a lot of info.
