Sit back in a soft seat in the lounge and watch the scenery pass while you're safe, dry and warm inside. Take the time to read the newspaper or relax with a good book, enjoy the scenery, or a cup of coffee.
You can check the email, take the important phone, arrange a meeting and get away work.
On many ferry connections there is access to the power take-off in the ferry lounge. This is based on mobile connection, and the available bandwidth can vary.
