I think the best solution to the PvE vs PVP problem is by adding NPCs to populate the world, not only to just make the world feel more alive but to possibly deter random violence and give players other targets to look for the in sea.
Examples
- Adding merchant ships piloted by NPCs would give the more blood thirsty players more targets to go after since the only way to experience ship combat currently is to go after other players.
- Populating the outposts with NPCs like random sailors and guards that defend the outposts from any pirates looking to start trouble (like spawn camping the outpost)
- Possible bounty hunter NPCs who hunt down those who are known to recklessly attack others on the sea. (could also be done by players for rewards)
