Race Winning Software Solutions: Deckman provides the best optimum routing algorithm for offshore racing alongside a suite of features for inshore racing.



The Optimum Routing module now includes the option to avoid areas with waves larger than a user set height – increasing speed and reducing the risk of damage to the boat offshore.

Enhanced Graphics

An enhanced graphics engine, including new layline options and shaded limit layline sectors, helps the navigator visualise wind shift limits when approaching a mark of the course.

Deckman’s wide set of features allows the navigator to optimise strategy and tactics whilst racing, and allow structured testing while tuning and training. 

Inshore the Start screen - giving live updates of boat position, favoured end, gain/loss through line bias and time to line - is the key to consistently good starts. Add in the ability to quickly generate windward/leeward courses, track wind-shifts and overlay tidally adjusted laylines on the chart whilst assessing strategic options on future legs and you have a clear advantage on the race course.

A competitor handicap tool allows you to keep track of competitors in handicap events with race position calculations based on user input of mark rounding times.


Offshore the navigator’s focus is on the weather. Deckman provides the best optimum routing calculations available, as used to win all the classic ocean races.

Deckman allows the user to animate multiple GRIB weather files including wind, pressure, precipitation and wave height to visualise the
weather forecast data. With UGRIB, OCENS Weathernet and Saildocs services integrated the navigator need never be more than a few clicks
from the latest weather downloads.

Using the Optimum Routing module the navigator can calculate the fastest route, whilst also using wave avoidance to route around areas
with dangerous wave heights. Reverse isochrones can be used, along with competitor tracking, to determine relative positions in the fleet.

Polar Tables

Other key features for offshore use include the use of multiple polar tables, one for performance targets, one for navigation – allowing the
navigator to adjust one polar to be accurate for the actual performance of the yacht, while the crew strive to attain 100% performance based on
their own polar.

Performance testing is possible via a suite of integrated data logging and analysis tools to allow accurate assessment of the performance of the yacht and crew under different conditions, during or after a race.


Single boat testing, such as a comparison of headsails, is accomplished by running Speed Tests to allow statistical comparison of one sail versus another, with a polar table overlay.

Multi boat campaigns utilise Deckman’s Two-Boat module to share data via a telemetry link, allowing wind-shift compensated performance comparison between yachts.

In either case Deckman’s integrated database logs all available data every second for 7 days, then at reduced frequency for a full year, allowing analysis of historical data against current performance.
