...how long ago did we all forget about the presence of water in Heroes! Anyway, the map is cool...
Yes, and only the sailing skill and the captain's hat remind us of past adventures.
Add-ons are an interesting thing, but not very popular.
...It's better to make a good map...
I would gladly play in a "Pirate" tournament with a choice of 5 different sizes and compositions of sailing maps (for example, 2 M, 2 L, and 1 XL), and maybe a successful map will be found and will participate in every tournament.
