You mean you want to play a similar game like High Seas Trader, which was a naval business simulation/combat video game ?? Single or Multiplayer ?
Try some of these, but since I'm not into Naval simulation/naval combat games, this list might NOT be fully accurate or relevant for you. But I tried my best to scour the internet, lol. So please keep this in mind:

You are asking me or "tennis2" ? But anyways, No, I don't have more similar game options to recommend. Was the above list helpful or not ? Maybe others out here might know better about Naval Simulation/Combat.
BTW, if you like playing RPGs with some Naval combat, then try playing Assassin's Creed IV: Black Flag. Obviously, this is not a full Naval Combat game, because AC series mostly focus on stealth/action/parkour, but the game is really awesome !
Black Flag took the excellent naval combat system from AC3 and turned it into a huge pirate game. Exploring the Caribbean never got old, as there was always something to discover both on land and sea. Edward Kenway was also a welcoming protagonist as he was more of an antihero compared to Altair, Ezio, and Connor.
In fact many agree that Black Flag is one of the best AC games ever made. Even AC1 and AC2 are pretty much praised, but Black Flag also got excellent feedback. The graphics are really awesome, and realistic.
But AC: UNITY is the best looking AC game till now, at least when it comes to graphics. But you don't get any Naval combat, exploration or simulation in this game though.
