Teleporio™ — Greek Island Travel Intelligence

How the Teleporio Score™ Works

How Teleporio calculates the Teleporio Score™ — time efficiency, cost, sea state and connection buffer. Plain-language explanation of the four-dimension ferry scoring system.

How Teleporio Calculates the Teleporio Score™

The Teleporio Score™ is a 0-100 rating applied to each available ferry or flight option on a Greek island route. It compresses four measurable dimensions — time efficiency, cost efficiency, sea state, and connection buffer — into a single number that tells you, at a glance, how good a specific option is on a specific day. A Score of 90 means all four factors are working in your favour. A Score of 44 means at least one factor is a real problem worth knowing about before you book. The Score is not an opinion or a star rating; it is a weighted calculation derived from route data, Beaufort forecast, vessel type, operator schedules, and port connection parameters.

The Four Dimensions of the Teleporio Score

• Time Efficiency (30%): How fast is this option relative to the fastest available on this route? A crossing that takes twice as long as the fastest alternative loses significant points. Direct routes without layovers score highest.
• Cost Efficiency (20%): How fairly priced is this option relative to the cheapest on the route? We normalise cost against median pricing so seasonal surges and cheap-but-slow options are both captured accurately.
• Sea State (35%): What does the forecast Beaufort level do to this specific vessel type? A catamaran in Beaufort 5 scores very differently from a large Blue Star conventional ferry in the same conditions. Vessel sensitivity is built into the calculation.
• Connection Buffer (15%): Is there enough time between this arrival and the next departure to absorb a realistic delay? A 45-minute connection in Piraeus with a 20-minute port walk scores poorly even if the schedule appears to work on paper.

How Sea State Is Calculated by Vessel Type

The sea-state dimension is the most technically complex part of the Score. Greek ferries are not all equally affected by wind and wave conditions. A Blue Star large conventional ferry continues operating through Beaufort 7 and occasionally Beaufort 8; a high-speed catamaran cancels at Beaufort 6 and is uncomfortable at Beaufort 5. A short-hop caïque cancels at Beaufort 5. Teleporio maintains a vessel sensitivity table that maps each vessel type to a sea-state score at each Beaufort level. The forecast Beaufort for your specific departure time on your specific date is applied to this table to generate the sea-state component of your Score. This is why the same route can score 88 at 08:00 and 44 at 15:00 on the same day in July: the Beaufort forecast is different, and so is the sea-state Score.

How to Read and Use the Score

• Score 90-100: All four factors are working. Book with confidence. This Score range is most common in May-June and September on morning departures.
• Score 75-89: One minor factor is suboptimal. A solid choice for most travellers — understand what the lower factor is before booking.
• Score 60-74: Two factors below ideal. Worth spending 10 minutes looking at alternatives. The Schedule comparison view shows what is dragging the Score.
• Score 40-59: At least one factor is a real problem. Check alternative departure times, vessel types, or routing options before committing.
• Score 0-39: Significant risk. Look for alternatives — another departure time, a larger vessel, or a different day.

What the Score Cannot Tell You

The Teleporio Score is a planning tool, not an infallible oracle. It uses forecast Beaufort conditions which update but are not real-time weather data. It does not account for mechanical delays, industrial action, or port congestion. It is not a booking platform — Teleporio helps you decide what to book, and you book through the operator or a booking platform like Ferryhopper. The Score is most reliable for planning 1-7 days ahead; beyond 10 days, the Beaufort forecast uncertainty degrades the sea-state calculation. And it will not tell you which island to choose — it calculates the quality of the connection you have specified. The island choice is yours.

Applying the Score in Practice

The most effective use of the Teleporio Score is comparative. Run your target crossing and look at the Score across all available departures for your date. You will typically see a clear pattern: morning departures scoring 80-90, afternoon departures scoring 50-70, with the Score gap widest in July-August. This tells you the optimal departure time in seconds, without needing to understand Beaufort scales or vessel specifications. If every option on your date scores below 65, consider moving your crossing to the following day — a delay of 24 hours in a Greek port is not a disaster, and a Score of 85 the next morning is a significantly better journey than a Score of 55 today in the afternoon.
