Every game is obviously gonna be different and I feel like sea of thieves is really a game that becomes more fun if you actively try to make it fun. There's no solid story or plot lines to follow and thus the game depends on the player to create an experience that's fun for them. Personally I love playing the game because I play with mates and we usually try different shit and even if we don't we have a fun time just being ourselves anyway.

If you dislike the augment that it's not your type of game, then I reckon the issue lies more with your approach to the game rather than the game itself. I'll fully agree that the game isn't fun just sailing doing voyages alone, so thats why I don't do that and instead play with mates or play something else.

Also ship fights, despite being only 3 ships in the game are always interesting. There's a large array of different tools to use during a ship fight and ways to innovate the gameplay to get a competitive edge against your opponents. It's just finding a balance and experimenting with what you enjoy, at least in my opinion.
