Eclipse Anchors Arc's Manufacturing Scale

Leading both rounds means Eclipse is not just financing Arc, it is underwriting the hardest part of the company, turning an electric boat prototype into repeatable manufacturing. Arc raised $30 million in November 2021 and $70 million in September 2023, then used that capital to expand from one premium day cruiser into wake boats, center console boats, and commercial tug systems. That pattern fits a capital intensive company that needs patient backers comfortable funding engineering, tooling, and production ramp at each step.

• Arc is vertically integrated, building hulls, battery packs, power electronics, and software itself. That gives it more control over performance and costs, but it also means each growth stage needs more money than a brand that only sells motors or software. A repeat lead investor helps bridge those manufacturing jumps.
• The investor pattern also signals confidence beyond consumer boats. Arc has already moved into commercial vessels, including an eight tugboat deal with Curtin Maritime valued at $160 million, with first deliveries planned by 2027. That is the kind of long sales cycle and delivery risk that usually rewards a concentrated institutional sponsor.

• Comparable electric boat companies show why this matters. Candela raised $40 million to scale hydrofoils with Groupe Beneteau, while X Shore raised $4.5 million to expand manufacturing. In this category, funding is closely tied to factory buildout and delivery capacity, not just customer acquisition.

Going forward, Arc is becoming less like a niche boat brand and more like an electrified marine OEM. If Eclipse continues to anchor financings, that gives Arc a cleaner path to fund factory scale, support commercial contracts, and push into larger vessel categories where incumbents still rely on diesel and dealer networks.
