MB Marine LLC

What MB Marine LLC does

MB Marine LLC is a family-owned marine machining and repair business operating from a single workshop at 135 Ellis Street, Staten Island, New York. Founded in 2005 by Maria Williams and Edward Brito, the company provides precision manufacturing and repair services for tugboats and other marine vessels, with a core focus on shafts, rudders, pumps, and custom-machined specialty components. The founders bring over 40 years of combined industry experience, including Edward Brito's prior 25-year tenure managing another marine machine shop, which underwrites the company's technical capability in specialized marine component work.

The business model is straightforward professional services revenue generated per job, with quote-based pricing on each repair or manufacturing engagement. There are no published rate cards; customers contact the company directly by phone or email for estimates. Go-to-market is entirely direct-to-customer and relies on word-of-mouth referrals within the regional tugboat and maritime community, supplemented by a basic website and email newsletter signup. The company maintains minimal digital infrastructure — no e-commerce, no app, no API, no social media presence of consequence — and operates with a headcount of 1-10 employees.

MB Marine serves a narrow customer base of commercial tugboat owners and operators in the New York region who need fast-turnaround, quality machining work to minimize vessel downtime. The company does not disclose financial information, has not raised outside funding, and has no known partnerships, acquisitions, certifications, or regulatory actions on record. Its competitive position is anchored on the founders' accumulated trade expertise and physical proximity to New York Harbor's working tugboat fleet.
