Marine Surveyor in Portland, Maine
Sewall Marine Surveying is based in the Portland, Maine area, providing professional pre-purchase and insurance condition and valuation marine surveys throughout Casco Bay, Southern Maine and Mid Coast Maine. As a locally operated practice, we offer careful, methodical vessel inspections tailored to the needs of serious buyers, insurers, and lenders.
Portland is one of Maine’s most active boating communities, with a diverse fleet ranging from classic Downeast vessels and cruising sailboats to modern powerboats and yachts. We regularly conduct surveys at marinas and boatyards in Portland and South Portland, as well as in nearby harbors throughout Casco Bay, Falmouth, Freeport, Harpswell, and surrounding coastal towns. We also provide services throughout New England such as Barrington, Rhode Island with a few arrangements.
Pre-Purchase Marine Surveys in Portland
Purchasing a vessel in coastal Maine requires a detailed understanding of hull integrity, structural components, propulsion systems, electrical systems, and onboard safety equipment. Our pre-purchase surveys are thorough, clearly documented, and designed to provide buyers with an accurate assessment of a vessel’s overall condition.
We understand the regional factors that affect boats in Maine waters, including seasonal storage, freeze-thaw cycles, moisture intrusion, and the impact of saltwater use. Our reports reflect these realities and are prepared with clarity and professionalism.
Insurance Surveys
Insurance carriers often require current condition and valuation surveys for vessels operating in Portland Harbor, Casco Bay and the Maine coast. We provide organized, well-structured reports suitable for underwriting review, including documentation of systems, deficiencies, and fair market value where applicable.
Our work is conducted with attention to detail and an understanding of the standards expected by insurers and financial institutions.
