Range Planning on a Full Tank
When people talk about “range,” it often sounds like a technical calculation.
Maximum distance. Exact fuel burn. Perfect conditions.
That mindset makes sense offshore — but it does not really fit how we cruise on the Rideau Canal.
For us, range planning is not about how far Lucky Enough can go on a full tank.
It is about how relaxed, flexible, and comfortable a trip feels without ever worrying about fuel.
What a Full Tank Really Represents
On the Rideau, a full tank is less about distance and more about freedom.
It means:
- No pressure to push farther than planned
- No stress about detours, weather changes, or slow zones
- No temptation to stretch fuel just to “make it” somewhere
A full tank gives us options.
Options to linger.
Options to change plans.
Options to stop early or keep going if the day feels right.
Why Distance Alone Is the Wrong Metric
Cruising on the Rideau is a mix of very different conditions:
- Long no-wake stretches at displacement speed
- Short open-water runs on lakes
- Idle time waiting for locks
- Docking, maneuvering, and slow approaches
Because of that mix, fuel use is not linear.
Trying to translate a full tank into a single “range number” gives a false sense of precision.
Instead of asking “How many kilometres can we go?” we plan around:
- How many cruising days we want between fuel stops
- How much reserve we are comfortable keeping
- Where fuel is readily available along the route
Our Practical Planning Approach
We plan trips assuming we will never use the entire tank.
A healthy reserve is always part of the plan, not an emergency margin.
In practice, that means:
- Fuel stops are planned well before the tank gets low
- Trips are broken into natural segments between marinas or towns
- Open-water cruising is used deliberately, not continuously
This approach removes range anxiety entirely.
Fuel becomes a background consideration instead of a constant calculation.
Rideau-Specific Reality
One of the advantages of the Rideau system is accessibility.
Fuel is available at regular intervals, and most cruising days involve modest distances.
That means range planning is really about pacing:
- Choosing comfortable daily distances
- Allowing time for locks and shore stops
- Ending days with plenty of fuel remaining
A full tank does not mean “go as far as possible.”
It means “go as comfortably as possible.”
The Bottom Line
For Lucky Enough, range planning on a full tank is not a number on a chart.
It is a mindset.
We cruise knowing:
- We always have more fuel than we need for the day
- We never plan to arrive anywhere near empty
- Fuel planning supports the trip — it never drives it
That confidence is what makes cruising feel easy.
And that is what a full tank is really for.
