At Sloan Mason Insurance Services, Inc., we specialize in tailored Marine General Liability Insurance for businesses operating in the maritime and waterfront sectors. As a wholesale broker with deep marine expertise, we provide agents and brokers with the underwriting guidance and market access needed to place hard-to-place and complex marine risks. Ideal Accounts and Appetite Our Marine General Liability program targets a broad range of maritime and waterfront operations where both land- and water-based exposures exist. We focus on accounts that require a nuanced understanding of marine liabilities and flexible placement options. Typical classes include: Diving contractors Dock and wharf construction Dredging contractors Labor contractors Marine construction contractors Painting and sandblasting contractors Shipyards Ship repair subcontractors Stevedores Wharfingers Terminal operators Examples of good fits: you might have a client that operates a small shipyard on the Gulf Coast, or a contractor who performs underwater welding and requires coverage for both wet and dry operations. These types of accounts are exactly what this program is built to address. Coverage Highlights and Advantages This program provides broad Marine General Liability protection designed for maritime operations exposed to third-party bodily injury and property damage. Key features include: Limits up to $1,000,000 per occurrence Coverage for third-party bodily injury and property damage Customizable endorsements tailored to specific marine operations Options to address both wet (watercraft/boarding) and dry (onshore/marine construction) exposures Policy wording and endorsements are selected with maritime exposures in mind so insureds receive coverage that aligns with operational realities on docks, vessels, and waterfront job sites. Underwriting Notes and Minimum Premiums We work with a range of admitted and non-admitted carriers to deliver flexible placement options. Underwriting is deliberate and risk-focused—especially for complex operations—and we welcome detailed submissions. Minimum premiums start at $15,000, depending on class of business, limits, and loss history. For faster review, provide a completed application, detailed operations descriptions, recent loss runs, and any safety or risk-control documentation available.
