Valhalla Boatworks has begun the second phase of an expansion at its Viking Mullica facility in Egg Harbor City, N.J.

The initial phase, a 6,000-square-foot addition to the fiberglass area, took place last year.

“This was the first of a two-phase expansion to increase manufacturing space at this facility, where we build our V-33, V-37, V-41 and V-46,” Valhalla said in a project update yesterday.

The second phase is a 12,000-square-foot, two-story addition that will be used to produce additional fiberglass parts, the company said. The building was started in May, with most of the steel infrastructure erected over the past week. Completion is expected this summer.

“Phase I of the project has allowed us to better organize the manufacturing space,” said Viking Mullica general manager John Leek IV in the update. “And this latest project will continue our efforts to improve our build efficiency.”
