A UNESCO World Heritage site, the Sea of Cortez is one of the most diverse seas on the planet with the widest variety of whales and dolphins, and home to nearly 900 species of fish.

Separating the Baja California Peninsula from the Mexican mainland, this narrow sea (also known as The Gulf of California) is home to a unique and rich ecosystem and sustains a large number of marine mammals, many of which are rare and endangered. It hosts many migratory species including the blue whale.

Furthermore, its more than 900 islands are important nesting sites for thousands of seabirds, and its waters are primary breeding, feeding, and nursing grounds for a myriad of migratory and resident species.

Mechudo is a small and exclusive catamaran, beautifully designed and a perfect size to offer great sailing opportunities around Baja. Its legendary name comes from a location near La Paz Bay where a pearl diver named Mechudo mysteriously disappeared after refusing to donate his beautiful pearl to the church.


Operating in Mexico’s Baja Peninsula, the Searcher is a 28-metre vessel, skippered by a captain with over 30 years experience of sailing these waters. She has 14 air-conditioned cabins and is an ideal choice for exceptional whale watching opportunities and a quality natural history experience.
