Command and Control Intelligence

Steering Control Core

The control core is built to keep steering calm, make mode changes explicit and keep recovery behavior predictable when conditions get messy.

How AI Helps Inside The Autopilot

Here, AI is not a chatbot, a cloud service or a black-box skipper. It is a local decision-support layer inside the autopilot. It follows live boat motion, heading, heel, rate of turn, wind, rudder command and boat response so the system can understand how the vessel is behaving in the current sea state.

That information helps the autopilot reduce unnecessary rudder hunting, adapt steering to waves, detect unstable motion earlier and give better advice to the skipper. The skipper remains in command at all times.

Mode Ownership And Intent

  • Modes are treated as skipper commands, not background suggestions. STBY, HDG, WIND and CRS/TRK carry explicit operator intent.
  • WORK mode is a high-workload safety profile. It lets the autopilot favor boat stability over exact course keeping when the skipper needs to work on deck.
  • RACE mode is an explicit performance profile layered on course steering. It is available for heading-only racing and can extend to mark or course-to-steer racing when the required navigation data is valid.
  • Command acknowledgement prevents silent mode mismatch.
  • Source-validity gates reduce accidental control on stale data.
  • Manual authority remains available for immediate skipper intervention.

Anti-Hunt Steering Behavior

  • Rate-aware and error-aware control reduces constant rudder chasing.
  • Sea-state adaptation damps over-correction in short, steep waves.
  • Settle logic after sharp transitions helps avoid whipping the boat back and forth.
  • Confidence weighting takes sensor freshness and route quality into account.
  • The private high-speed NMEA exchange keeps control-loop latency low inside the core cluster.

Tack/Gybe, Route And WORK Context

  • Maneuvers are tracked from request through completion.
  • Tack and gybe can be delayed after the skipper presses the command, giving time to prepare sheets, warn crew or finish a deck task before the turn starts.
  • In light wind, the core can deliberately steer past the final target by a configurable overshoot angle during tack/gybe, then hold briefly before correcting back to the wanted course.
  • That controlled overshoot helps fill the sails and rebuild flow before the boat settles onto the best course again, instead of stopping too early with soft sails and poor drive.
  • After a maneuver, the system can hold safe control while route intent is re-evaluated.
  • Explicit avoid-and-resume workflows are supported.
  • Warnings are raised before potentially unsafe wind-angle transitions.
  • WORK mode can give stability priority over strict course keeping, helping the boat stay as settled as possible while the skipper handles maintenance, sail work or other deck tasks.

Failover And Alarm Strategy

  • Retries are bounded, and stale data is detected on the command path.
  • Low-confidence hazards default to fail-closed behavior.
  • AIS/RADAR advisory and alarm hooks support traffic and collision-risk awareness.
  • The latest recovery reason and counters remain visible for diagnostics.
  • If the system degrades, the operator sees it. Important state changes do not happen silently.

Feedback And Comments

This project is still in progress, and I would genuinely like feedback on what is missing, what feels unclear, and what would be most useful offshore. The first sea trial is planned for the 2026 sailing season, and every comment is reviewed by me before it appears publicly.

Comments do not appear immediately. I review and approve them manually before anything is published on the site. Please avoid posting private contact details that should not be visible on the web.

Built For Singlehanded Offshore Reality

These public pages focus on what the suite actually delivers offshore: steadier steering, fail-safe automation, and practical offshore support that reduces workload without taking control away from the skipper.
