About us

A passion for sea

It was in Sagres that our team of marine biologists dreamed of exploring the ocean. In order to promote an active community in the conservation of the ocean, we offer boat tours with environmental interpretation. We run marine biology research projects, supervise academic theses and internships, and deliver courses and talks. We also give support to research projects from partner institutions.

Ricardo Silva

Marine biologist and co-founder of Mar Ilimitado in 2005. He is responsible for the companies’ operationality. Allied to his long navigating experience is his underwater experience. He collaborated as a skipper with the University of the Azores integrating several scientific projects, especially whale & dolphin research, fish telemetry and scientific diving, but he also worked as a skipper at different whale watching companies there. Besides skipper, he is a diving instructor and a commercial diver. We all count on his experience and friendliness.

Sebastião Pernes

Enthusiastic about nature, the sea and photography. His relationship with the ocean began 40 years ago. He joined our team in 2010: without hesitating he stepped aboard and left his small fishing boat with which he dazzled the tourists visiting grottoes. Since then, he became our skipper and no one knows the coastal secrets or enjoys the north wind as much as he does! He knows the region through his feet, for he is also a hiking guide. He is fluent in Portuguese, English, French, German and Spanish. His experience with the sea, nature and life is a reference to all of us.

Jorge Narciso

The ocean has been part of his life since a young age. Practiced sailing for ten years, attended the Nautical School and worked in aquaculture and fishing. Today he is one of our skippers and you can expect a good time on board with him. Besides this, he is our handyman doing a bit of everything at our office... He is truly a does it all!

Ana Poças

Marine Biologist. Has an interest for conservation and animal behaviour in the marine environment, topics with which she worked closely during her Master studies. While previously working as an environmental educator she discovered the power of sharing knowledge about nature and how to protect it. As a guide at Mar Ilimitado she can ally her passion for the sea and her desire to share nature.
