Lind Marine

What Lind Marine does

Lind Marine is a full-service marine operations company founded in 1906 and headquartered in Vallejo, California, serving the San Francisco Bay Area, Sacramento-San Joaquin Delta, and broader West Coast markets. The company provides specialized dredging, marine construction (pile driving, seawalls, jetty repair), tug and barge transport, ship lightering, salvage and demolition, environmental remediation, and shipyard services through a fleet of 40+ vessels, including six tugboats and 22+ barges such as the Peter Lind, the West Coast's largest bulk materials barge at 430 feet. The company also operates a 400-foot by 100-foot graving dock at Mare Island, a wholly-owned subsidiary Moose Boats that has built 110+ custom diesel aluminum catamarans for law enforcement, military, and industrial clients, and a Pacific Pearl product line of oyster shell calcium supplements and AG lime products mined from Suisun Bay deposits.

Lind Marine's revenue model is primarily project-based and contract-driven, with services billed directly to municipal, government, industrial, utility, and waterfront owner customers through direct sales engagement. The firm supplements service revenue with hardware sales of sand, gravel, and oyster shell products distributed from Mare Island and Petaluma aggregate terminals, and usage-based revenue from equipment rentals and charter of tugs, barges, cranes, and workboats. The company holds an extensive stack of regulatory credentials including USACE contracting eligibility, US Coast Guard Subchapter M compliance, MSHA, OSHA, HAZWOPER, Gold Shovel, and ISNetworld contractor status, alongside a California General Engineering Contractor License.

The business was family-controlled for over a century before Kingswood Capital Management and Seneca Partners acquired the company in 2022 alongside the Lind family. In May 2026, Tallvine Partners acquired Lind Marine as the West Coast anchor of its North American marine infrastructure platform, which also includes East Coast operator Donjon Marine (acquired September 2025), with CEO Christian Lind continuing to lead the company under its existing brand. The Tallvine integration positions Lind Marine to participate in a bicoastal marine services platform targeting large-scale federal and private contracts.
