How reliable are Cape Verde ferries?

The short answer: the short crossings are dependable; the long ones are not always. São Vicente–Santo Antão runs several times a day, every day, and rarely fails. The longer inter-island lines — the Sotavento run to Fogo, Brava and Maio, and the Redonda circuit through São Nicolau, Sal and Boa Vista — depend on one vessel each. When that vessel has a problem, the whole line changes for days.

That is not a warning against taking the ferry. It is the difference between a trip that absorbs a delay and a trip that doesn't.

What actually goes wrong

Three things, roughly in order of how often they bite:

Schedule changes. Sailing times move — sometimes by hours, sometimes to a different day — and the change is often announced only a few days ahead. This is the single most common surprise, and it is why a timetable you screenshotted last month may already be wrong.

Weather. The Atlantic between the islands is roughest from November to March. Rough seas mean delays, uncomfortable crossings, and occasionally cancelled sailings — most often on the longer, more exposed southern and circuit routes. The short São Vicente–Santo Antão channel runs in most conditions.

Technical problems. Each of the long lines is served by a single ship. If it needs repair, that line does not simply pause — the operator reshuffles the whole network: another vessel is borrowed to cover the most critical links, sailings are rescheduled, some islands wait.

What operators actually do when it happens

This is the part travellers rarely know in advance, and it is genuinely reassuring: CV Interilhas does not just cancel and go quiet. In practice, when a vessel goes out of service, they publish an adapted operating model within a day or two — often reassigning a second ship to cover the most important routes — and then, once the vessel returns, run a programme of viagens extraordinárias (extra sailings) to clear the backlog of passengers and cargo. Announcements come through their official channels, sometimes updated more than once as the plan firms up.

The practical implication: if your sailing is disrupted, the replacement is usually days, not weeks — and there is usually a published plan. What you need is a way to see the current version of that plan, and enough slack in your itinerary to use it.

And in high season they add capacity rather than just coping. In August, when demand outstrips the regular timetable, CV Interilhas has run extra Santiago–Fogo–Brava and Santiago–Maio sailings on days those routes do not normally operate. So the August answer to "there's no boat that day" is sometimes "not on the regular schedule — but check anyway."

Which routes are most and least reliable

Most dependable — São Vicente ↔ Santo Antão (Mindelo–Porto Novo). Two operators, several sailings a day, a one-hour crossing on a short channel. If you need one ferry in your trip to work, this is the one. It is also the only way to reach Santo Antão at all.

Generally solid, but fewer chances — Santiago ↔ Fogo ↔ Brava, Santiago ↔ Maio (Sotavento). These run several times a week rather than several times a day. The crossings themselves are routine; the exposure is that a missed or cancelled sailing may mean waiting a day or more for the next one. Brava has no airport, so a cancellation there is absolute — there is no flying out instead.

Plan with slack — the Redonda circuit (São Nicolau, Sal, Boa Vista, Santiago). Long legs, some overnight, and a schedule that alternates on a fortnightly rotation, so the sailing days genuinely differ from one week to the next. Do not assume last week's pattern; check the dates you actually travel.

How to plan around it

Leave a buffer day before any flight home. This is the single most valuable rule on this page. If your international flight leaves Praia on Sunday, do not plan to arrive from Fogo on Saturday evening. One day of slack turns a disruption into an inconvenience instead of a missed flight.

Check close to travel, not once when you book. Schedules are typically published only a few weeks ahead and can be amended within the week. Re-check a few days before, and again the day before.

Treat printed or screenshotted timetables as historical. They were true when they were made. Ondas exists precisely because the live answer and the printed answer diverge.

Know your fallback before you need it. For most islands the fallback is a domestic flight; for Santo Antão and Brava there is no fallback — no airport, ferry only. Build those two into your itinerary with the most slack.

Arrive early. Thirty to forty-five minutes before departure. Boarding closes before the advertised departure time, and ferries leave on time even when they arrive late.

So — should you rely on the ferry?

Yes, with a plan. Locals do, every day, and the network is the country's backbone. The islands' ferries are not a resort shuttle; they are working transport in the middle of the Atlantic, run by two operators with a handful of ships. Judged as that, they are reasonably good — and the operators communicate more than most travellers expect.

The mistake is not taking the ferry. The mistake is building an itinerary with no slack and then discovering, on the wrong afternoon, that the sea had other plans.

Common questions

Are Cape Verde ferries often cancelled?

Outright cancellations are not routine, but schedule changes are common, and weather or technical problems do cancel sailings — most often on the longer routes and most often between November and March. The short São Vicente–Santo Antão crossing is the most dependable in the country.

What happens if my ferry is cancelled?

Operators generally publish an adapted schedule within a day or two, often reassigning another vessel to cover key routes, and run extra sailings afterwards to clear the backlog. Contact the operator about your ticket, and check the live schedule for the revised sailings.

How far in advance can I book a Cape Verde ferry?

Not far. Schedules are usually published only a few weeks ahead, so booking months in advance generally isn't possible. Plan the shape of your trip early, confirm the sailings close to the date.

Which Cape Verde islands can only be reached by ferry?

Santo Antão and Brava. Neither has a working airport, so the ferry is the only way in and out — worth extra buffer time in any itinerary that includes them.

Are the crossings rough?

The Atlantic can be lively, especially November to March and on the longer, more exposed routes. The one-hour São Vicente–Santo Antão channel is short even when choppy. If you're prone to seasickness, sit low and central, and prefer the shorter crossings when you have a choice.
