The UK’s Port of Southampton and PortMiami in the US have signed an official international sister seaports agreement.

The pact is aimed at boosting the cruise market in both cities and share mutual best practices.

PortMiami is claimed to be the leading cruise port in the world, while the facility in Southampton is considered one of the top cruise turnaround sites in Europe.

Every year, nearly two million cruise passengers visit the Port of Southampton. The port brings in £2m to the economy with every cruise call.

Similarly, PortMiami is recognised as the Global Gateway. It contributes $41.4bn to the local economy per annum and supports more than 324,352 jobs in South Florida.

In addition, a city twinning agreement was signed at the Mayor’s Parlour at the Civic centre.

PortMiami director Juan Kuryla and Miami-Dade County mayor Carlos Gimenez signed the agreement with Port of Southampton director Alastair Welch.

Welch said: “We are pleased to be officially linked with our friends at PortMiami and hope we can mutually benefit from lessons learned around successes seen on both sides.”

Kuryla said: “Miami-Dade County and Southampton have much in common. Our ports are both leaders in trade and tourism through our cargo and cruise activity.

“I look forward to growing our relationship as sister cities and sister ports through the strengthening of our cultural and commercial ties, and I anticipate the development of economic opportunities for us both.”

Recently, MSC Cruises revealed plans to build a terminal at PortMiami.
