How We Keep Our Fleet Safe in Lisbon
27 August 2026
Certification, maintenance with Servocean and a qualified crew. The behind-the-scenes work that keeps a Lisbon boat tour safe, and what to check before booking.

Booking a boat tour in Lisbon is, for most visitors, a simple decision: you find a company you like, check the reviews and book. But behind every good tour lies a good deal of work before the first passenger boards: maintenance, safety checks, crew training, regulatory compliance and the ongoing relationship with the people who keep the boats in condition. In this article we share that behind-the-scenes reality, not because we expect you to think about engine maintenance while watching the sunset over the Tagus, but because transparency about how we operate is part of what makes Sardinha do Tejo a company you can trust.
Why safety matters more than you think
The Tagus estuary is generally a calm body of water, which makes it easy to underestimate the complexity of operating on it safely. In practice, conditions can change quickly: wind, tidal current, the traffic of larger vessels and the challenges of navigating near the bank all demand constant attention from experienced crews. On top of that, the boats themselves require regular, professional maintenance to stay seaworthy. Unlike a car, where a minor fault means pulling over, a problem with a boat in the middle of the river calls for a completely different response. That is why we take a zero-tolerance approach to maintenance.
Our maintenance partner, Servocean
The boats operated by Sardinha do Tejo are maintained by Servocean, a company specialising in marine maintenance. Their team handles scheduled maintenance, safety inspections and any technical work needed to keep our fleet in certified condition. Working with a dedicated marine maintenance partner means our boats are serviced by professionals who work exclusively in the sector. Unlike general mechanics or improvised maintenance, this specialist focus ensures that every system on our boats is inspected and maintained to the standards required for commercial passenger operations.
Equipment and crew on board
On board, safety is always present, even when discreet: enough life jackets, emergency equipment, means of communication and proper signage. But the most important factor is the crew. Experienced professionals who know the river, the tides and the conditions of the Tagus are the real assurance of a smooth trip. They read the weather, adjust the route if needed and make sure everything goes well, while also turning the tour into a good experience.
What to check when booking a boat tour in Lisbon
If you are comparing operators, these are the questions worth asking:
- Is the operator certified by Turismo de Portugal? This is the baseline certification for tourism operators in Portugal.
- Are the boats inspected regularly? Ask whether maintenance is done in-house or by a company specialising in marine work.
- Does the crew hold maritime qualifications? All skippers of commercial passenger vessels in Portugal are required to have them.
- Is passenger insurance included? All legitimate operators include public liability insurance for passengers.
- What is the bad-weather policy? A responsible operator cancels or reschedules tours when conditions are unsafe, and refunds passengers. At Sardinha do Tejo, safety is the basis of everything, so all you have to worry about is enjoying the river. See the options at Lisbon boat tours and, if you have any questions, talk to us.
