Port Royale Marina and Lakeside Community, formerly Lan Mar Marina, showed off its new look Saturday during a grand opening celebration.

The site on Lake Lanier in northeastern Forsyth County has been the focus of a multimillion dollar expansion over the last two years.

Owner Doug Traina, the founder and chief executive officer of T.E.I. Industries Inc., the umbrella company, has a master plan for the property that will make Port Royale a lakeside resort and private home community.

The 10-year effort calls for a resort hotel, rental cabins, restaurant and additional amenities. It also will include a 50-home subdivision with private dock access.

Brent Danneman, general manager of Park Marine Boats Sales, said in a statement that the lake “hasn’t seen construction like this in over 40 years.”

“It’s a welcomed and much needed addition,” he said.

To date, the property has a new leasing center and modern service center that sit atop one side of the lake’s bank. From there, marina-goers can see the Lighthouse at the Port, billed as the largest floating boating center in the country.

The 60,000-square-foot, neon-lit complex houses food, drinks, ice, lake accessories and clothing, as well as Park Marine Boat Sales, the company's boat sales operation.

The lighthouse also is the new home of Paradise Rental Boats-Lake Lanier.

In addition, more than 200 boat slips of all sizes have been added, with hundreds more in the works, including 86 super-sized houseboat slips that offer open-water views of the lake.

T.E.I.’s group of companies include, among others, Park Marina and Wilderness Camp Marina, both on Lake Allatoona, and Park Marine Boating Center in Gainesville.
