More than 40% of new ship MSC Seashore has been redesigned and enhanced as a “significant evolution and improvement” over its two sister ships.

The differences to MSC Seaside and MSC Seaview include 200 extra cabins, a larger ‘ship within a ship’ MSC Yacht Club and an additional double deck lounge at the rear.

The latest MSC Cruises’ vessel, due to enter service in June 2021, will have 10,000 square metres of additional deck space with a 16-metre extension to 339 metres, making it the longest vessel in the fleet.

Features include 28 more terraced suites and two suites with private whirlpools.

The expanded MSC Yacht Club will include two new cabin categories – 41 deluxe grand suites and two owner’s suites with whirlpools.

A ‘cluster cabin’ concept for families – where two or three adjoining cabins can be linked to accommodate between six and ten people – will be introduced, while 75 larger cabins for disabled passengers are added.

Two new restaurants are planned alongside a new location for five specialty dining outlets to allow for al fresco waterfront seating on the ship’s boardwalk.

The interior has been redesigned with two central meeting points positioned at the middle and forward part of the ship, as well as specific measures to improve passenger flows.

MSC Seashore will have a bigger casino and 20 specialty bars.

The ship will feature a new design of its aft swimming pool, an enlarged indoor pool and a new waterpark. Clubs for young children and teenagers have been separated from a larger kids’ zone.

A range of environmental protection measures are to be installed including a selective catalytic reduction system designed to help cut nitrogen oxide by 90% through advanced active emissions control technology.

Wastewater will go through a purification and filtration process that transforms it to “near tap-water” quality.

The new-build will also be fitted with shore-to-ship power connections while in port to reduce emissions.

The details emerged at a keel laying ceremony for the ship at the Fincantieri shipyard in Monfalcone, Italy.

MSC Cruises’ executive chairman Pierfrancesco Vago said: “Today’s ceremony marks another key milestone in the construction of one of our most innovative all-around ships yet.

“Most importantly, MSC Seashore – which will feature the latest and most advanced environmental technology currently available – represents another proof of our long-standing commitment to preserve the environment in our ongoing journey to minimise and continuously reduce the impact of our operations.”

Fincantieri CEO Giuseppe Bono added: “The beginning of drydock works of MSC Seashore, the largest ship so far built in Italy, is for us a source of great satisfaction.

“It is a real challenge in terms of structural and managerial aspects, which powers the impressive workload for the shipyard and the local area.”
