The sound of heavy machinery scraping against rocks and an overwhelming smell of diesel fuel invade an otherwise serene desert beach where Mexico will spend roughly $100 million building its first cruise-ship home port.

The Mexican government chose to build the port in the sleepy beach town of Puerto Peñasco, better known as Rocky Point, because of its proximity to the United States and potential as a future international tourism destination.

“It is the most important project the city has ever had,” said Miguel Guevara, director of promotion and international affairs for the city.

Construction workers spend their days dumping rocks, making concrete blocks and placing them along the breakwater to prepare the port for a January 2017 opening.

Officials said they hope the roughly mile-long port will tap into the growing cruise-ship industry by offering passengers an opportunity to explore the Sea of Cortez.

Proponents said the port could attract 3,000 new weekly visitors and transform the city’s economy.

However, critics said the port could negatively impact local residents, wildlife and biodiversity.

Rocky Point is about 200 miles southwest of Phoenix and Tucson in Sonora, Mexico, along the Gulf of California. Some have nicknamed the town “Arizona’s beach” because it’s a three and half hour drive from both cities.

Tourism in the town, historically driven by fishing, is increasing with a majority of the town’s visitors coming from Arizona.

Rosie Glover, a co-founder of the Rocky Point Tourism and Visitor Assistance Office, said the increase in tourism has been “surprisingly dramatic and not gradual at all.”

Guevara said tourism dropped after the 2009 recession and though the city has not fully recovered, some have seen impressive gains.

“For the last six months or more, we’ve been busy every single week,” Glover said.

Residents said there’s been talk around the town about the home port for decades, but many people didn’t take the project seriously until recently, when construction began in December 2013.

The government has already spent roughly $40 million on the port, which is about 50 percent completed, Guevara said.

Mexican authorities support the project because it will benefit the entire country’s economy, said Jose Luís Castro, director of port operations for the Sonora government’s tourism department.

Castro said money would flow into cities situated on the cruise ships’ routes, like San Felipe, Cabo San Lucas and Mazatlan.

Joe Houchin, who has followed the cruise industry for decades, said the cities have opportunities for repeat visitors because 80 percent of cruise goers choose land vacations based on the destinations they visit on a cruise.

Castro said millions of the country’s residents want to take a cruise, but don’t have visas — leaving that market largely untapped.

In addition, officials hope to attract millions of international visitors annually.

“Our main market is and will always be Arizona, but the home port will bring people from other states to come and start their trip on the Sea of Cortez,” Guevara said.

The proximity to the U.S. made the town an ideal location, said Gustavo Brown, owner of Sandy Beach Resorts.

“With half a tank full of gas, you’ve got a whole family at the destination,” Brown said of Arizonans.

Brown donated 12 acres of land for the construction of the home port and terminal on Sandy Beach, just west of the tourist strip.

“Our dream is to create a mega tourist resort in which we could have people from all around the world to come see us,” Brown said.

Hotels and condominiums that line a strip of oceanfront property distinguish the town as a tourist destination, but Rocky Point is on a much smaller scale compared with cities like Cancun and Acapulco.

Although other resort towns serve as popular ports of call for cruise ships, Rocky Point’s home port will serve as a departure and arrival point for passengers.

It will start small and eventually host 3,000-passenger ships.

Officials said they brought in the best contractors in the world for the project, which will include a state-of-the-art terminal and convention center.

Guevara hopes the port will be a catalyst for new projects in the town.

“We’re like 20 years behind (Puerto) Vallarta and 30 behind Cancun, but yeah, why not?” Guevara said.

“We are closer to the U.S. than anywhere else, so why not? That’s a good dream,” he said.

Cruise industry

Guevara said this is the first test to see what the area can do with the cruise industry.

“There’s a need for new routes for cruises,” Guevara said.

Passengers would get a unique view of the waters of the Sea of Cortez, Castro said.

“The cruise liners also suggested (the home port) because it’s an area where they haven’t exploited,” Project Administrator Wendy Winzer said.

In 2009, about 17.8 million people took cruises. In 2013, that number grew to 21.3 million, according to Cruise Lines International Association, an industry association.

Last year, major cruise lines added 22 ships, which made room for 20,000 more beds, according to the association’s website.

Houchin, who lives in Rocky Point, said cruise liners are building bigger ships to accommodate the increasing passenger volume.

“They will send the smaller ones to more exotic destinations, such as Puerto Peñasco, we hope,” Houchin said.

Houchin writes a monthly economic impact blog about the home port for Sandy Beach Resort.

He said people should expect major airlines to begin applying for landing rights at the Puerto Peñasco International Airport.

However, some cruise-liner officials expressed concerns over the small town’s ability to accommodate an influx of visitors.

If tourism swells to the level officials hope, the city will need to improve hotels, roads and airport access, Castro said.

“I think the city is not ready yet,” Guevara said.

However, Guevara said the infrastructure and supplies would be ready by the time the port opens.

“We can bring all the components together really fast,” he said.
