History and shipyard
Delta Marine has operated from Seattle’s Duwamish River area since its founding and remains owned and run by the Jones family. The company’s early work focused on rugged commercial boats for Northwest waters, then broadened into luxury yacht construction and refit. Its official materials describe the yard as a custom builder with deep roots in the Pacific Northwest and customers worldwide. Public profiles also place the shipyard in Seattle and note that it serves both new-build and repair work.
Model range and construction
Delta Marine builds custom yachts rather than a fixed production line, with published references placing its size capability at up to 100 meters. The yard is known for composite construction and also works in steel and aluminum. Sources describe its output as including expedition yachts, motor yachts, and other custom superyachts, often built in collaboration with an owner’s outside design team or with Delta’s in-house naval architecture and design staff. The brand is especially associated with large, one-off vessels and advanced composites.
