IIRC you'll also need to buy the latest paper chart for the Upper Humber (they're updated frequently, so you should probably do this close to your departure date). You can get them from the chandlers in Hull. You can also find the charts at Humber.com... it's the bi-monthly you're looking for, such as https://abpnotify.co.uk/AbpPublishedDocuments/_Upper Humber Bi-Monthly - February 2022.pdf
I assume you have the chart outbound from the Humber Bridge at least on a chart plotter . If not I would says that's essential . I would not want to be without it.
Visibility one time became nil very suddenly just outside Grimsby.
