About Wayfarer Labs

Independent engineering · Switzerland
Wayfarer Labs is built on decades of experience turning complex science and data into practical systems. Its creator holds a PhD in computer science and brings extensive director-level experience at a global healthcare company, leading work across strategic intelligence, data science and product development.
That work connects clinical science and operations with portfolio management, finance, manufacturing, regulatory affairs and patient advocacy. It uses digital twins, predictive engines and decision intelligence to understand complex systems, anticipate outcomes and support better decisions.
The same discipline shapes what we build here: make assumptions explicit, test predictions against reality, and give people information they can act on. For our marine systems, that means taking the work aboard boats, where real passages put the models, software and hardware to the test.
Telltale / Sailing intelligence
Our coastal wind and wave models combine physics with data science. Boat-specific routing, anchorage assessment and connected instruments put those fields into the context of your passage.

Marine hardware / Cooling, defrost & airflow
A retrofit controller designed to manage refrigeration automatically, coordinating compressor effort, intelligent defrosting and air circulation. Use temperature feedback and available power to maintain the required cooling while reducing avoidable energy use.
Discuss your installation ↗
HOW IT WORKS
Five temperature points across the box, evaporator and airflow.
Coordinate compressor speed, defrost cycles and fan speeds within the configured temperature limits.
Schedule cooling around available power, with local control and optional Telltale integration for the boat’s energy budget.
Development & evidence
Initial integration targets Danfoss BD35 and BD50 compressors. The display brings temperature, power, energy and defrost information together. Savings must be established by comparing equivalent cooling work under measured conditions.
Development proposal. No measured energy-saving percentage is claimed.
SYSTEM OVERVIEW
Thermal feedback closes the loop.
Telltale adds energy context when connected.
Marine hardware / Windlass & thruster
A wireless handheld and base station for anchoring. Chain length, depth, scope and seabed context sit together, while the original footswitches and wired controls remain available.
Discuss compatibility ↗
HOW IT WORKS
Distinct physical controls for windlass and bow thruster.
Chain count follows movement from the handheld or the boat’s original controls.
Measured chain length can feed the anchor watch and voyage log.
Development & evidence
The proposed architecture preserves the boat’s original controls. The fitted trial must verify command response, chain count and coexistence across both control paths. Standalone operation does not require an app or server.
In development. Fitted acceptance testing remains part of the release work.
PROPOSED CONTROL PATH
Original wired controls → windlass
Independent command path remains available.
Marine hardware / Machine vision
A stabilised thermal and daylight camera concept. Combine viewing angles with mast height and vessel attitude to estimate where a water-level contact lies.
Discuss the prototype ↗
HOW IT WORKS
Thermal and daylight imagery from a stabilised masthead pod.
Mast height and corrected viewing angle estimate water-level range.
Telltale supplies heading, position and attitude for chart-referenced contacts.
Development & evidence
Passive ranging depends on the contact being at water level and on the accuracy of height and viewing angle. A near-horizontal sightline is particularly sensitive to angle error. The proposed laser rangefinder provides another measurement at suitable ranges.
Prototype programme. Published specifications are design targets until verified on a fitted unit.

Beta help →Wayfarer Labs / Methods across the portfolio
We work across numerical simulation, machine learning, sensing and embedded control. The common discipline is to represent the system carefully, preserve the evidence behind each output, and test it against the conditions it will encounter.
Telltale / Implemented models · validation scoped by study
Geospatial computing · Numerical physics · Route optimisation
Telltale combines atmospheric forecasts, terrain, coastlines, bathymetry and vessel data. Our wind and coastal-wave models calculate local physical responses; routing applies those fields to a particular boat and passage.
The scale of a passage calculation
Weather fields describe the area around a passage across time and model scenarios. The router then explores candidate courses using the boat’s performance and passage constraints.
scalar entries in the five-model corridor example below, including a separate directional wave field.
boat-speed evaluations across five weather scenarios with endpoints 100 nm apart.
of global ERA5 reanalysis available, combining observations with physical modelling since 1940.
A nominal 100 nm × 20 nm corridor, tiled at 500 m, gives 371 × 75 cells. Across 40 forecast snapshots:
| Spatial cells | 27,825 |
|---|---|
| Five model scenarios × eight variables | 27,825 × 40 × 5 × 8 44,520,000 scalar values |
| One 24-direction wave field | 27,825 × 40 × 24 26,712,000 directional entries |
| Combined inventory | 71,232,000 entries |
The eight example variables are two wind components, gust speed, wave height, period and direction, and two current components. The directional wave field is counted once, not once for each atmospheric model.
This is transparent sizing arithmetic, not an instrumented production payload. Model availability, native grids, coverage, masking, crop, cadence and enabled layers vary. It does not mean every source supplies every variable. These are scalar field entries, not independent observations, learned parameters or newly computed values for every route. Regional TCW and wave fields can be shared across many passages.
The current Python routing engine was run on five synthetic weather scenarios using one sample polar, a fastest-route objective and the benchmark’s all-sea geometry. Each case included wave fields and endpoints 100 nm apart.
| Boat-speed evaluations | 104,070 |
|---|---|
| Wind sampling calls | 3,474 |
| Marine sampling calls | 3,474 |
| Variability sampling calls | 3,469 |
| Returned route lengths | 103.5–108.5 nm |
Measured reference workload, not a typical-cost promise or a five-provider live comparison. Counts refer to function calls and can reuse cached values. They exclude TCW field construction and cannot be added to the field inventory as a total number of datapoints. Coastlines, wind, polar, objectives and search settings change the workload.
Inspect the recorded counts ↗ERA5 reconstructs global weather from 1940 onwards by combining observations with a physical atmospheric model. Our documented Mediterranean study uses selected historical periods and episodes, including a 2017–June 2021 reanalysis leg. Archive coverage is not a claim that the complete archive has been downloaded or that Telltale has been validated across every year.
ERA5 archive and methodology · ECMWF ↗Multidimensional fields vary across latitude, longitude, forecast lead and model run. Terrain and bathymetry have different resolutions; station observations and vessel streams have different footprints, clocks and uncertainty. Joining them requires explicit units, coordinate systems, masks and valid times.
Diagnostic wind downscaling combines stability-dependent lee wakes, ridge acceleration, channel effects and parametrised thermal circulation. A screened-Poisson correction, solved with conjugate gradients, adjusts horizontal flow around obstacles. The coastal-wave model transports directional energy through refraction, shelter, breaking and approximate diffraction and reflection.
Python, NumPy and SciPy support array computation and sparse numerical solves. Regional fields are built and published for reuse rather than recalculated for each viewer. Boat-specific polars and timed fields feed isochrone routing. The web app renders the resulting fields directly.
Historical reconstruction and operational forecast replay answer different questions. Retain the original run and lead, compare at the reference scale, and examine speed bias, direction error and behaviour by terrain regime. Observed station comparisons are distinct from showing a plausible-looking field.

direction bins in that benchmark configuration
paired comparisons in the separate regional forecast-selection study
The wave solver uses one representative period per cell, without currents or the full frequency spectrum. Diffraction is approximate. The wind model is diagnostic downscaling, not a full atmospheric simulation. Grid spacing is not an accuracy guarantee.
Numerical methods are present in the local model source. Benchmark dimensions are documented developer measurements, not a reproduced performance test. The 60,015 comparisons cover 45 stations and 1–48-hour leads for HRDPS/HRRR selection; they do not validate TCW terrain corrections.
Dataset complexity & scale
A forecast cube, a race-history table and a stream of camera frames pose different problems. Volume matters alongside resolution, coverage, information timing, missingness and the independence of observations.
We distinguish source coverage, data actually processed, training samples and independent evaluation samples. Each published figure should carry its period, configuration and purpose.
