Arc scales via operator and shipyard partnerships
Arc
Arc is using channel partners to skip the hardest part of industrial selling, which is winning trust inside a small, relationship driven tug market. Tug operators do not buy like recreational boat buyers. They buy through long operating histories, shipyard relationships, port experience, and financing confidence. By working with Curtin Maritime and Diversified Marine, Arc gets those distribution and credibility layers at the same time it gets product feedback from real operators.

Curtin Maritime is not just a customer, it is a reference account with scale. The $160 million deal for eight hybrid electric ship assist tugs gives Arc a live fleet program in Los Angeles and Long Beach, which is far more persuasive to other harbor operators than a standalone sales pitch from a startup manufacturer.

Diversified Marine plays a different role. The partnership on Arc's first electric truckable tug lets Arc prove its drivetrain in a retrofit project with an established shipyard partner, which shortens the path from prototype to a working commercial vessel operators can inspect, test, and compare against diesel boats they already run.

This matters because industrial marine sales are usually local and hands on. Buyers care about who builds the hull, who services the vessel, where it operates, and whether it meets port requirements. Partnering with operators and shipyards lets Arc plug into those buying workflows instead of building a national enterprise sales force from scratch.
If Arc keeps turning early operator partnerships into deployed vessels, commercial sales can compound through port by port proof rather than headcount growth. That creates a durable wedge into harbor craft electrification, where the winning vendor is likely to be the one already embedded with operators, shipyards, and charging infrastructure before the market fully opens.
