What we’re building

Our vision is to electrify all waterborne vessels, and we're starting with electric water sport boats.

Gas boats dominate today’s marine industry not because of great product offerings but because of a lack of better alternatives. Boaters have grown accustomed to vehicles that feel stuck in the 1980s: unreliable, expensive, loud, noxious, and a nightmare to own and operate. They’re also awful for the water and air they reside in.

By contrast, electric boats are superior in nearly every way: not only are they far more reliable and less costly to operate, but they’re also quieter, quicker, and cleaner, with no fumes or pollutants. However, they’ve been held back by both the technology and the talent to make them truly competitive with gas alternatives. That’s Arc’s opportunity.

Using modern, aerospace- and automotive-inspired techniques, we’re building our hulls, batteries, cooling systems, firmware, and software together...
