A Harder Maritime (Mega) Puzzle Mystery Cache

Here at Naval Base 31 on the edge of the Atlantic we live a regimented life, trying to learn to live as a mariner does, and communicate as a mariner does.

Here’s an example of our daily schedule:

• 1:37 – Repair sails
• 4:37 – Scrape the barnacles off the hull
• 5:45 – Check the rigging

• 16:30 – Some of us coil ropes
• 16:30 – The rest of us swab the decks
• 18:01 – Feed the Captain’s parrot

Doesn’t leave us much time for geocaching, but then again… maybe it does.
