Before you start reading, please be aware this idea is supposed a way of expanding content available exclusively for boats, nothing has been theory tested. I'm bad at making that kind of things so I'll just make this short and easy to comprehend.

These seas are supposed to be the boat-only worlds. While inside this world, the boat's health will display instead of your health. Exiting your boat will damage you for 10% of your health per second. These world are broken into 4 portals with different difficulties and rewards.
In these worlds, you can find:
This new world opens up an opportunity for adding new kind of crafting materials, boxes that drop from them and much more. It's up to the devs to think about it.
U3 and U4 Dangerous Sea worlds are supposed to be the hardest and can only be managed through teaming up with friends but should yield the most rewards.
Repair Sketches allow you to repair your ship. Whilst in the Dangerous Sea world, your ship's health will slowly increase but sometimes it's not enough. Repair Skethes can be considered as Boat Potions.
Boats have high attack speed so Damage stats needs to be kind of low or the enemies' health has to be higher than normal.
Dangerous Seas' portals act like the other portals, except these are blue-ish.
These worlds can open up new opportunities for challenges to be added, such an example would be *Kill 50 Sea monsters in 10 minutes for 2 neon dragon caches, 3x bonus for U4*
Thanks for reading and I hope this idea gets taken into consideration.
