SHIP SHAPE Four boat businesses offer one-stop service under one roof. By Sean Mulready For The Patriot Ledger Mike Borrelli thinks he has found an answer for boating enthusiasts who don't want to travel from shop to shop to get all the repairs they need for their boats. The Hanover resident recently opened the Marine Service Center on VFW Drive in Rockland in a 14,000 sq. ft. building formerly used as a metal fabrication shop. To create a one-stop-shopping location for boaters, Borrelli united experienced marine specialists who can handle all kinds of boat repairs involving motors, electrical systems, graphics, canvas work and his own specialty, fiberglass. What's unusual, at least for this area, about an enterprise of his size is that the four specialists all run separate businesses under one roof. Dave Asci runs Black Diamond Marine in Borrelli's building. He works with Vincent DiTullio, who runs the yacht brokerage part of Black Diamond Marine at the site. Bryan Connery's South Shore Graphix occupies part of the wing, next to Rockland Canvas Design. "We're complementing each others' businesses," said Mike Borrelli who moved there in May and said he leases the space to the other three tenants. "There's nothing that we can't do under this roof." The idea came to him over the past few seasons as he realized that his firm, Metan Marine Restoration, couldn't continue to grow behind his Hanover home. At first, he thought of heading to Florida. But he realized he didn't want to leave this area and that having multiple businesses all in the same place offered benefits for business owners and customers. Bill Drummer of Scituate found that out shortly after the Marine Center opened. "In a lot of marine-type places...it's hard to get someone to talk to you for more that two minutes, unless you've got money falling out of your pockets," Drummer said "(When) I came in here, Mike was sitting up in his office - and they barely even got the doors open yet - and he was willing to talk to me about boats." Drummer wound up paying for work on his 24-foot Rabalo power boat from three of four businesses at the Marine Service Center. With about 100 years of marine work represented in the businesses at the center, Borrelli hopes people will see the advantages he feels it provides - particularly for owners of boats that are 30 feet or smaller. But first, he knows people have to find out what it's all about. He has taken out ads, will send out tens of thousands of fliers and is inviting boaters to a Sept. 12 open house.
