Bay Marine Service/Storage/Marina has joined the Topside Marinas Family!

We are thrilled to share some exciting news with you! TopSide Marinas, a family-owned company that acquires and operates high-quality marinas around the country, has recently acquired Bay Marine of Sturgeon Bay and Bay Marine of Chicago. With this acquisition, TopSide Marinas now owns and operates a total of 10 marinas across six states.

The previous owners, Matt and Mark Felhofer, will continue to own and operate Bay Marine Yacht Sales, leasing back showroom and office space at both locations. This ensures a seamless transition and continued high-quality service.

It’s important to know that Topside plans on keeping the look and feel of both locations. For the most part, our customers should not see any change.


“With the acquisition of Bay Marine service, storage, and marina operations, TopSide Marinas will now be running two of the finest marinas and boatyards in the Great Lakes,” said Ryan Skiles, Regional Vice President of Operations at TopSide Marinas.

“Bay Marine’s Waukegan facility is an outstanding service and storage facility with deep water access to the downtown Chicago harbors. Bay Marine of Sturgeon Bay Yacht Harbor facility was completely remodeled in 2022, which brought one of the Great Lake’s most historic marinas back to the prominence it had in the 1950’s. The acquisition of Bay Marine reinforces TopSide’s mission of fostering a high-quality environment where our members and guests can create lifelong memories while maintaining an enjoyable waterfront experience for the avid boating communities in Wisconsin and Illinois.”

“This is an exciting transition for Bay Marine and our entire team of over forty employees in the Midwest,” said Matt Felhofer, President of Bay Marine Yacht Sales. “The marine industry has seen dramatic consolidation over the past several years and TopSide Marinas presented a unique opportunity for us to bring in a partner that has the knowledge, expertise, and capital to take our existing service, storage, and marina businesses to the next level while allowing our sales team to focus on growing our key brands throughout the Great Lakes market.”

“Matt and Mark Felhofer have built an impressive business at these two outstanding locations. We regard them highly and are excited to partner with them as they grow Bay Marine Yacht Sales to one of the largest yacht brokerage firms in the region,” said Jacob Boan, Co-founder, and Chief Investment Officer of TopSide Marinas.

TopSide Marinas is dedicated to expanding its footprint in key destinations across the country. By leveraging our expertise in property management and top-notch customer service, we aim to elevate each marina’s offerings while preserving their unique charm and character.

Thank you for being a valued member of our marina community. We look forward to continuing to serve you with the highest standards and creating memorable experiences for all our members and guests.
