Key Benefits

• Enhanced performance: Maintains optimal sail shape through gusts and shifts for higher VMG and better pointing/downwind stability.
• Lower workload: Automates routine trimming; ideal for shorthanded sailing and night passages.
• Safety & reliability: Prevents over‑trim, protects sails/rigging in squalls, and balances loads to reduce broach risk.
• Efficiency: Minimizes drag and complements hybrid/aux propulsion to reduce fuel use under motor‑sail.
• Data you can trust: Live dashboards for apparent/true wind, sheet loads and trim state with event logs for debriefs.

What We Install

• Sensors: Ultrasonic wind (masthead), boom angle, vang/kicker position, traveler position, load cells on sheets/halyards/backstay.
• Actuation: Electric or hydraulic primary winches, traveler actuators, in‑boom/in‑mast furling interfaces, powered backstay.
• Control: Trim controller with adaptive algorithms, manual overrides, watch‑standing modes (performance, cruise, heavy weather).
• Displays & UI: Helm and nav‑station pages with presets, alarms and context tips.
• Networking: NMEA 2000/0183‑compliant integration with leading autopilots and MFDs.

We tailor components to your rig (sloop, cutter, ketch), sailplan (slab or furling main, overlapping/non‑overlapping headsails) and power system (12/24 VDC, hydraulic).

Integration

• Autopilot: Share heading/heel data and coordinate trim during tacks/gybes.
• Navigation & routing: Use polars and weather routing targets to maintain best VMG.
• Power system: Load‑aware logic to respect battery state and generator duty cycle.
• Safety systems: High‑load and knockdown alarms with auto‑easing rules.

Our Process
Assessment & Design
Survey rigging, deck leads and electrical/hydraulic capacity; capture sailing goals and operating profile. Deliver a layout with sensor/actuator placement and cable runs.
Component Sourcing
Specify marine‑grade sensors, winches/actuators, controllers and displays rated for vibration, water ingress and UV.
Installation & Integration
Fit sensors (mast/deck), route looms, mount control hardware, and integrate with autopilot, plotter and onboard bus.
Calibration & Sea Trial
Calibrate wind and load references; validate responses for upwind, reaching and downwind; fine‑tune control gains.
Handover, Training & Maintenance
Crew training (operations, modes, overrides), maintenance schedule, and remote diagnostics enablement.

Operating Modes

• Cruise: Comfort‑biased; trims for minimal heel and reduced winch duty.
• Performance: Targets polar‑based VMG; aggressive response to shifts.
• Heavy Weather: Load‑limiting, reef‑aware, with conservative easing rules.
• Manual Assist: You trim; system provides live targets and prompts.

Common Problems We Solve

• Inconsistent trim & crew fatigue: Automated, repeatable trim logic reduces workload and error.
• Speed loss in variable breeze: Real‑time adjustments keep sails in the power band through lulls and gusts.
• Sail/rig wear: Load monitoring prevents chronic over‑trim and extends service life.
• Integration headaches: Clean, warrantable integration with your existing nav, pilot and power systems.

Maintenance & Support

• Scheduled inspections for sensors, sheaves and terminals
• Firmware updates and log reviews
• Load cell zeroing and winch duty‑cycle checks
• Remote health monitoring and fault alerts (where enabled)

Technical Options

• Power: 12/24 VDC electric, hydraulic central unit, or hybrid
• Networking: NMEA 2000 backbone with appropriate tees/terminations
• Redundancy: Dual power feeds and mechanical bypasses for critical controls
• Environmental: IP‑rated enclosures, UV‑stable cabling, marine‑grade connectors

FAQs
Will the system work with my existing autopilot and plotter?
We design around open marine standards (e.g., NMEA 2000/0183). Most modern pilots and MFDs integrate cleanly with the trim controller.
Can I override the system instantly?
Yes—helm‑level hard keys enable immediate manual control and emergency dump/ease.
Is this only for racers?
No. Cruisers benefit from comfort, safety and shorthanded operation; racers gain repeatable performance and data logging.
What about energy consumption?
We size actuation and set duty cycles to your batteries/generation profile, with modes that minimize draw on passage.

Next Steps

• Request a proposal: Share your yacht specs (LOA, displacement, rig, sailplan, power system).
• Onboard survey: We inspect routing paths, mounting points and integration points.
• Sea trial & training: Commissioning includes real‑world tuning and crew handover.
