Ferry travel planning: sort every item into four columns
Ferry travel planning in four columns, committed, allowance, optional and unknown, so every crossing, room and risk has a source, a date and an owner.
What to take away
This is a method for sorting a ferry trip before you spend on it, not a list of fares; the amounts come from your own route's quotes.
- Build a budget for ferry travel costs from dated quotes for your route, not national averages.
- Separate committed costs, allowances and unknowns, and never let an unknown quietly become zero.
- Price the risk of a lost sailing as a line item, because on some routes it is the largest single variable.
- Public climate and water level records let you estimate that risk rather than feel it.
Four columns, not one number
Write the budget as four columns and the fuzziness disappears.
Four Budget Columns
Committed
- What it is
- Quoted, dated, in writing
- Examples
- Booked crossing, paid room
- Discipline
- Keep proof
Allowance
- What it is
- Figure you control
- Examples
- Food or fuel
- Discipline
- Set the cap
Optional
- What it is
- Would enjoy but drop
- Examples
- Upgrades, extras
- Discipline
- Cut first
Unknown
- What it is
- Unconfirmed, named, dated
- Examples
- Unresolved questions
- Discipline
- Owner and deadline
- Committed.Quoted, dated, in writing. A booked crossing, a paid room.
- Allowance.A sensible figure you control, such as food or fuel.
- Optional.Things you would enjoy but would drop.
- Unknown.Anything you have not confirmed, with a name attached and a date to resolve it.
The discipline is in the fourth column. An unknown is not a small number, it is an unresolved question. Give each one an owner and a deadline, and by the time you travel the column should be empty.
A worked example: a walk-on day across Puget Sound
Take a walk-on day on Washington State Ferries' Seattle / Bainbridge Island route, one of the routes WSDOT lists on its ferries site, where tickets can be bought online. The columns fill in like this, with every amount taken from the day's own quotes rather than from this page:
- Committed:the walk-on ticket bought online, with the confirmation saved and dated.
- Allowance:lunch on the island side, and local transport if you are not walking from the terminal.
- Optional:a museum or a bike rental you would drop if the day runs short.
- Unknown:parking near the Seattle terminal until you have a dated quote, and the evening sailing you would need if the afternoon one is canceled, until you have checked the schedule and the ferry alerts.
Add a vehicle and the committed column changes shape: the vehicle fare depends on its length and height class, so measure before you ask for the quote. Move the same day to a long ocean route and the unknown column grows, because a lost sailing there can mean extra nights.
Get quotes, not averages
For anything route-specific, ask the supplier and record the answer with a date. That means the operator for the crossing, the property for the room, the guide for the trip. A published average across a whole coast tells you nothing about a particular Tuesday on a particular route with a vehicle.
Quote, Don't Average
- Ask the operator for the crossing
- Ask the property for the room
- Ask the guide for the trip
- Record the answer with a date
- Screenshot the confirmation
Screenshot the confirmation. Terms change, pages get updated, and a dated record is what settles a dispute later. This is also why we do not print fares here: a number in an article is undated by the time you read it.
Estimate the weather risk from the record
The largest uncontrolled variable in a ferry budget is a day you do not get; published records, not anecdote, let you estimate its likelihood.
NOAA's Climate Data Records are vetted time series measurements built for longevity, consistency, and continuity. The National Research Council sets the standards they are assessed against, and they support community preparedness and resource management. They show what a stretch of coast typically does in a given month.
Water level matters on routes with tidal terminals. NOAA's water level information pages describe the National Water Level Observation Network: more than 200 permanent stations on the coasts and Great Lakes. They produce the nation's official tidal predictions and the reference datums used for nautical charting and coastal engineering.
The same page notes the largest Great Lakes tides are only about five centimeters. A lakes route and a Gulf of Maine route are not the same planning problem.
Where budgets actually break
| Line | Typical cause of overrun |
|---|---|
| Parking | Priced per day, trip runs longer than planned |
| Vehicle fare | Length or height class higher than assumed |
| Food | One expensive option on the island side |
| Accommodation | An unplanned night after a cancelation |
| Rebooking | Non-refundable ticket on a changed date |
Sanity checks before you commit
Ask whether every figure has a date and a source. Ask what the total becomes if you lose one day. Ask whether a cheaper season also means a thinner timetable, because that trade is often mispriced. Then compare the whole thing against the alternative, using the categories in our ferry trip cost breakdown, "Ferry trip costs split into three blocks, plus an example for two adults".
Common questions
Why will you not publish typical fares?
How big should the contingency be?
Is a vehicle ever the cheaper option?
Where do I start on the trip itself?
