Can I simply arrive at the port without submitting documents?

The name “gate visa” does not mean that travellers can arrive without preparation. During an operating season, the scheme may require documents to be sent through a designated channel before departure, with further checks completed at the border. Current official instructions explain what must be submitted and how the procedure works. Buying a ferry ticket is not equivalent to making a visa application. A carrier’s operational guidance can be useful, but it does not replace official eligibility rules. Check passport, accommodation, return-travel and other evidence requirements before travelling, and verify current submission arrangements rather than relying on an earlier season.
