# SmartTrim.ai

> SmartTrim is the marine vessel-intelligence ecosystem from Walker Marine Technologies LLC, a founder-led marine technology company based in Dallas, Texas.

SmartTrim combines vessel motion, GPS and supported onboard data for performance analysis and, in products under development, adaptive trim and tab assistance. SmartTrim Logger and SmartTrim Prop are ready for pilot testing. SmartTrim Controller remains in development. SmartFleet is planned.

## Technical resources
- [What is automatic boat trim?](https://smarttrim.ai/resources/automatic-boat-trim/): Automatic boat trim uses vessel data and control logic to help adjust propulsion trim or related control surfaces as operating conditions change.
- [Automatic boat trim systems compared](https://smarttrim.ai/resources/automatic-boat-trim-systems-compared/): Factual comparison of SmartTrim Controller, Mercury Active Trim, Seakeeper Ride and Zipwake by control objective, sensors and control surfaces.
- [Pitch, roll and vessel attitude explained.](https://smarttrim.ai/resources/pitch-roll-vessel-attitude/): Vessel attitude describes how a boat is oriented and moving in three-dimensional space. For SmartTrim, pitch and roll are two of the most useful signals.
- [How trim angle affects boat performance.](https://smarttrim.ai/resources/trim-angle-boat-performance/): Trim changes the relationship between propulsive thrust and the hull’s running attitude, so a small adjustment can alter several parts of the ride at once.
- [How to compare boat propellers using data.](https://smarttrim.ai/resources/compare-boat-propellers-data/): A useful propeller test compares more than the single fastest GPS reading. It controls the test conditions and looks across the operating range.
- [What is NMEA 2000?](https://smarttrim.ai/resources/nmea-2000/): NMEA 2000 is a standardized marine data network that allows compatible equipment on a boat to exchange messages over a shared backbone.
- [What data can a modern marine engine provide?](https://smarttrim.ai/resources/marine-engine-data/): Modern propulsion systems can expose far more than RPM, but the exact set of usable signals varies significantly by engine, gateway and vessel network.
- [How SmartTrim uses sensor fusion.](https://smarttrim.ai/resources/sensor-fusion/): Sensor fusion turns multiple imperfect observations into a more useful vessel state by aligning them in time and interpreting them together.
- [Automatic trim vs. trim tabs: what is the difference?](https://smarttrim.ai/resources/automatic-trim-vs-trim-tabs/): Propulsion trim and trim tabs can both change how a boat rides, but they act on the vessel in different ways.
- [Boat performance data logging explained.](https://smarttrim.ai/resources/boat-performance-data-logging/): A good marine test log preserves the conditions and timing behind a result, not only the result itself.
