It’s another high-water mark for the Port of Charleston.

The Arthur Maersk is scheduled to steam through Charleston Harbor today, the longest to date in a conga line of outsized container ships to visit the Holy City. The 1,157-foot-long vessel is 2 feet longer than the Axel Maersk, which set the record in April.

These mega-ships are of the “Post-Panamax” class, meaning they’re too big to get through the Panama Canal. Shippers are shifting to them to save costs. Others are on their way, including the MSC ASYA, a 1,104-footer set to steam into port May 21.

By maritime standards, none of these behemoths are technically the largest container ships ever to drop anchor in Charleston. The 1,102-foot-long MSC Sindy, which tied up to the Wando Welch Terminal in 2011, is considered the biggest because it can hold the equivalent of 9,580 20-foot containers. That about 1,300 more than Arthur Maersk and 380 more than MSC ASYA.

TBonz to Homegrown

For nearly three decades, Charleston-based TBonz Restaurant Group has been serving diners at its collection of restaurant concepts in the Carolinas and Georgia. On May 21, the company will change its name to Homegrown Hospitality Group to better capture its business.

With 10 concepts in more than 20 restaurants and one bed-and-breakfast, founders Jerry Scheer and Mark Cumins think that while the TBonz name represents its roots, the company has grown into something much more diverse. The TBonz Foundation, the company’s charitable arm, will remain the same as a reminder of where the company started.

Flying to Chicago

Hawthorne Global Aviation Services is spreading its wings to the Midwest and the City of Big Shoulders.

The local company announced last week it’s building an aircraft servicing business at Chicago Executive Airport, the fourth busiest in Illinois. It has bought the rights to be the “fixed base operator,” or FBO, from another firm. Hawthorne said construction should be completed next year.

“The acquisition ... establishes our presence in Chicago, a vibrant top three general aviation market,” said Steven Levesque, CEO of Hawthorne.

FBOs provide plane owners with a variety of services, such as storage, fuel and ground transportation. Hawthorne Global Aviation was formed in 2010 by North Charleston-based Hawthorne Corp. and Moelis Capital. The Chicago deal marks the venture’s third FBO. The others are in New Orleans and Islip, N.Y.

‘Cool School’

You may have sampled Paolo’s Gelato at Paolo Dalla Zorza’s popular John Street shop in downtown Charleston. But there’s another side to his business.

In addition to his shop, he has a wholesale web-based business, GelatoSupply.com, which sells cups, spoons and other tools. What’s more, he is doubling the size of his warehouse off Azalea Drive in North Charleston and has added a frozen dessert lab with plans to open a gelato “Cool School.” It will teach and train culinary students and fans of cold desserts his tricks and secrets.
