Who Owns the Attessa Yacht in Cabo San Lucas?

If you've ever been on the water near Cabo San Lucas and spotted an enormous superyacht sitting on the horizon, there's a good chance it was the Attessa IV. At 332 feet long, it's impossible to miss — and it draws stares from every charter boat, water taxi, and fishing panga that passes by. Here's everything you need to know about it, and the man behind it.

So who owns the Attessa yacht in Cabo? The answer is Dennis Washington, an American billionaire from Montana who built one of the most diversified industrial empires in North America. The yacht is his flagship, and Cabo San Lucas is one of his favorite destinations.

Who Is Dennis Washington?

Dennis Washington was born on July 27, 1934, in Spokane, Washington, during the Great Depression. His early years were marked by hardship — he contracted polio at age eight and spent years moving between relatives across three states before settling in Missoula, Montana, with his grandmother.

He started his business career at age 30 in 1964 with a $30,000 loan and a single bulldozer. Five years later, Washington Construction had grown into the largest construction firm in Montana. From there, Washington diversified aggressively into mining, railroad operations, marine transportation, shipbuilding, aviation, and industrial services.

Today, The Washington Companies is a privately held conglomerate headquartered in Missoula, Montana. Dennis Washington's net worth is estimated at approximately $7.74 billion, placing him among the wealthiest individuals in the United States. He and his wife Phyllis have donated more than $130 million to charitable causes through their foundation, with a focus on education, healthcare, and community development.

This is not a tech billionaire or a Wall Street financier. Dennis Washington is a hands-in-the-dirt industrialist who built his fortune the old-fashioned way — one bulldozer load at a time.

The Attessa IV: What Makes This Superyacht Special

The yacht spotted in Cabo is most commonly the Attessa IV, though Washington has owned several vessels named Attessa over the years. The Attessa IV is the crown jewel.

Originally built in 1999 as the Evergreen for Chang Yu-fa, the chairman of Evergreen Shipping Line, the vessel was designed by Diana Yacht Design. Washington acquired it in 2007 and then undertook one of the most ambitious superyacht rebuilds in history. The transformation took three years and cost an estimated $200 million — a team of 225 workers, ten of whom were engineers, put in approximately one million man-hours. The hull was stretched from 298 feet to its current 332 feet.

The master suite includes his-and-hers dressing rooms, a private office, a private salon, private outdoor dining, and a private helicopter deck. Beyond the staterooms, the yacht contains a 12-seat cinema, a full spa, a state-of-the-art gym, and multiple deck spaces for entertaining.

Why Does the Attessa Come to Cabo?

Cabo San Lucas has long been a magnet for superyachts. The deep, protected waters of the marina, the calm anchorages in the bay, and the year-round sunshine make it one of the premier superyacht destinations in the Pacific. Washington is a repeat visitor, and both the Attessa and the larger Attessa IV have been photographed anchored in the waters off Los Cabos multiple times over the years.

According to SuperYacht Fan, both Washington vessels have appeared in Cabo simultaneously — a rare sight even by superyacht standards. SuperYacht Times has documented multiple visits, noting the yacht's distinctive profile against the Cabo skyline.

The Sea of Cortez is also one of the world's most biodiverse marine environments, which Jacques Cousteau famously called "the world's aquarium." For someone with the resources to go anywhere on earth, Baja California Sur keeps drawing them back.

You Don't Need to Own a Superyacht to Sail These Waters

Here's the thing that surprises most visitors: the same waters Dennis Washington sails on the Attessa IV are available to you too. You don't need a $200 million vessel or a billionaire's fortune. You just need the right charter company.

Our fleet ranges from an intimate 35-foot Sundancer up to the 252-foot La Datcha, covering every group size and every type of occasion. Every charter is private — the boat is yours for the duration, with no sharing the deck with strangers and no group tour schedule.
