    {
      "q": "How does the boat fuel consumption calculator work?",
      "a": "Engine horsepower and cruise hours drive fuel burn. This estimates gallons per hour, trip gallons, and total fuel cost so you can budget a day on the water. The underlying maths is: GPH ≈ HP × 0.05 × load%. Trip gallons = GPH × hours."
    },
    {
      "q": "What do I need to enter?",
      "a": "4 values: engine horsepower, average throttle load, hours running, and fuel price. Each field starts with a sensible default, so you can change one number at a time and watch the result move."
    },
    {
      "q": "What does the trip fuel cost result mean?",
      "a": "It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds."
    },
    {
      "q": "Is this calculator free, and do I need an account?",
      "a": "Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser."
    },
    {
      "q": "How accurate is the result?",
      "a": "It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary."
    },
    {
      "q": "Who is this tool for?",
      "a": "It's built for anyone doing everyday planning maths — a quick estimate that would otherwise need four browser tabs and a calculator app."
