Is it possible to say the mail's delivered by sea

What an interesting question!

While it's technically possible to transport mail by sea, it's not a common practice for several reasons:

  1. Cost: Shipping mail by sea is generally more expensive than using air transportation or land-based postal services.
  2. Speed: Sea travel is slower than air travel, which means mail would take longer to reach its destination.
  3. Reliability: Sea routes can be affected by weather conditions, such as storms or rough seas, which could delay or damage mail.
  4. Infrastructure: Most postal services have established networks and infrastructure for land-based and air-based mail transportation, but not for sea-based transportation.

However, there are some exceptions where mail is transported by sea:

  1. Island nations: Some island nations, like Hawaii or the Maldives, may use sea-based transportation for mail delivery due to their remote locations and limited air connectivity.
  2. Specialized services: There are some specialized services, like the US Postal Service's "Ocean Mail" service, which transports mail between the United States and its territories in the Pacific Ocean.
  3. Historical or nostalgic purposes: In some cases, mail may be transported by sea for historical or nostalgic purposes, such as reenactments of old sailing routes or special events.

In summary, while it's not a common practice, it is possible to say that mail is delivered by sea in specific circumstances, such as island nations, specialized services, or historical events.
