Drayage One
42m autonomous coastal freighter, electric-hybrid. Crewless point-to-point transit between four ports with autonomous dock-and-discharge, charged from shore between runs.
Overview
We don't launch ships. We deploy fleets.
Segal Shipyards designs and builds autonomous naval vessels across three theaters of the water — logistics, research, and aquatic living. One hull architecture, one autonomy stack, reskinned for cargo, for science, and for the people who live aboard.
A Segal hull is surveyed, modeled, fabricated, launched, and operated as one continuous system. It resolves its own sea state, holds station without a bridge crew, and reports its condition plank by plank — keel to commissioned hull in modular fabricated sections, not years on the ways.

Capabilities
LOGISTICS
Autonomous Logistics Hulls
Crewless freight and supply vessels that hold a sea lane, dock, and discharge without a bridge crew. Modular dry, reefer, and bulk bays on an electric-hybrid drivetrain, shore-charge ready.
RESEARCH
Ocean-Research Platforms
Sensor-dense hulls that hold station over a survey site for weeks — integrated wet labs, moonpool ROV bays, and seabed-mapping arrays rated to a 6,000 m working depth.
HABITATS
Aquatic Habitats
Floating residential and community platforms with closed-loop power, water, and waste. Modular berths from a single home to community scale, with storm-rated dynamic mooring.
LIVE
Helm — Autonomy Stack
Autonomous navigation and station-keeping: collision avoidance, dynamic positioning, and dock-and-discharge, certified to operate crewless on a standard transit.
BETA
Drydock — Hull Configurator
Configure and order a Segal hull from a live model — length, drivetrain, and module loadout — validated by a real-time constraint engine and priced with a delivery window.
ROADMAP
Tideline — Fleet Operations
The fleet-operations terminal: live position, hull-health telemetry, and utility status across every deployed vessel — survey to service life, reported in one place.
SURVEY → OPERATE
Modular Fabrication
Hulls built as standardized prefabricated sections across four yards — the same module becomes cargo bay, wet lab, or berth. Two platform classes: coastal and blue-water.
Case Studies
Sounding
Dynamically positioned research platform, 6 km ROV rating. Two labs and a moonpool bay streaming seabed and water-column data over multi-week deployments. In build at North Pacific Slipway.
Tide Commons
24-berth floating community with closed-loop power, water, and waste and storm-rated dynamic mooring. In build at Sheltered Bay Works.
Longhaul
Blue-water autonomous freighter: a sequenced fleet of 120 m cargo hulls coordinating routes, weather, and port slots through the Tideline terminal.
Atoll
Town-scale habitat ring — moored berth clusters and utility cores forming a small, self-sustaining community far from a conventional coastline.
