# Sea Machines SM300: Price, Availability & Status (2026)

Sea Machines is the 'pick-and-shovel' of maritime autonomy: SM300/SM200 vessel-agnostic retrofit kits, 200+ delivered. B2B licensing, no published consumer price.

## Price

_No verified price on record._

There is no published consumer price. Sea Machines is a B2B autonomy licensing business: it sells the autonomy brain (the SM300/SM200 retrofit kit) to vessel operators, not a consumer product, so DEPLOY records zero price points.

## Availability

_Status: internal-only_

Sea Machines sells to vessel operators, not consumers. Its SM300/SM200 kits are installed on existing or new-build workboats from 10 to 300 feet in two days or less, with more than 200 systems delivered worldwide.

## Status

Sea Machines Robotics (Boston; founded by Michael Johnson) is the autonomy-system-vendor archetype of the maritime category: it makes the autonomy brain, not the boat. Its SM300 and SM200 autonomous-command systems are vessel-agnostic retrofit kits, so the customer owns and operates the hull while Sea Machines licenses the autonomy onto it. The September 2025 SM300-NG adds class-society-approved hardware, a 200-percent compute increase, full voyage control with collision avoidance and sensor fusion, and worldwide remote command, alongside an attritable SM300-SP defense variant. DEPLOY records it at commercial maturity on a real shipping product, class-society approval, and more than 200 systems delivered, and credits it with units delivered rather than sea-days, since its autonomy runs on other companies' hulls.
