Tug Boat Cheat Codes: Which Game?

I need more context to help. "Tug boat" appears in many games:

• GTA Series: Tug (GTA V/Online), Tug (GTA SA — spawn code `AMOMHRER` on PC/PS2/Xbox).
• Sea of Thieves: Rowboat / Tug mechanics — no cheats (online only).
• Ship Simulators: Ship Simulator Extremes, Tug Masters — trainer tables exist (WeMod).
• Mobile/Indie: Tug Boat (various) — cheats unlikely.

Please specify:

1. Exact Game Title (Platform / Year).
2. What the cheat should do: Spawn, Infinite Fuel, Speed, Invincibility, Unlock?
3. Single-player or Multiplayer? (MP cheats = Ban).

With details, I can give the exact code or legitimate method.
