The company
A house for the business of the sea
From equipment to operations
SBI — Sea Business and Investments was created to serve the Iberian market for marine equipment and accessories: representing European builders of rigid-inflatable boats, trailers and deck materials, with the standards demanded by both leisure owners and professional operators.
In time, that technical knowledge took us onto the water: we are a registered maritime-tourism operator running trips and charters on the Tagus and along the coast, and we provide specialised technical services — maintenance, bathymetric surveys, structural inspections and synthetic-teak deck installation.
We work with private owners, companies, tour operators and professional entities that need the sea to simply work — every day, safely, with no surprises.

What guides us
Technical rigour
We specify, install and maintain as if the boat were our own — the sea doesn't forgive shortcuts.
Brands we trust
We only represent European manufacturers we would put on our own deck.
The sea as a craft
From tourism to bathymetry, the team lives the sea from the inside — not just the catalogue.

From Algés, the gateway to the Tagus
SBI is headquartered in Algés, Oeiras — five minutes from Belém, halfway between the Lisbon and Cascais marinas. From here we serve clients across the Iberian peninsula.
