Advanced real-time race scoring software for your sailing club.

arcSail can be quickly setup to score a single or multi-day regatta while powerful enough to score several season-long series simultaneously.

With its easy to use, familiar, touch interface for iPhone and iPad including many hand-crafted elements, arcSail makes scoring simple and intuitive. Custom time, number and calendar controls make setup easy and in app tips help get you started quickly. Sailors, Boats, Events and Fleets can be pre-configured or imported from Registration data, so that getting up and running on the water is a snap. Scorers order and tap boats from one or more fleets to finish. Once the races are run, handicapping and penalty calculations are applied instantly and results can be immediately emailed to shore (with in-app purchase on a data-capable device).

Wide range of scoring features, including:

• Short and long series calculations are supported using Low Point, Bonus Point, High Point Percentage, Low Point Average or Chips3 systems.
• Uncorrected (one-design) fleets and/or handicapped (mixed) fleets using Portsmouth Yardstick (PY), wind-strength corrected North American Portsmouth Yardstick (NAPY), Small Catamaran Handicap Rating System (SCHRS), PHRF Time-on-Time and Time-on-Distance can be easily scored.
• Custom handicap systems can be defined.
• Multiple simultaneous fleet starts and finishes tracking.
• Calculations follow the RRS & Appendix A guidelines.

With in-app purchase:

* Results can be emailed or Air Printed in HTML format for easy display on the club website or bulletin board.
* Data can be backed up to Apple Files and/or swapped between devices using email.

NAPY Support

Some time ago (years) when this app first came out I asked to help develop NAPY support. Though there was no reply I was surprised to see NAPY support. Thank you!

Being in the US there is no support for handicap dinghy racing at the national level (thanks for nothing USSailing). Appreciate the help from the other side of the pond.

There is a small learning curve with this app but it is easier than most.

Tried to use for a race but couldn’t figure it out

I tried to set up and run a single regatta with three fleets. The software is very limited and I couldn’t figure out how to do PHRF Time-On-Time corrections. It seemed to only do Time-On-Distance. And then when I tried to enter the finishing times for the boats after the race, it would only accept elapsed times, not the finish time. Thus, corrected times were not correct. I confirmed the error by doing a separate spreadsheet to calculate finishes. I have used Sailwave and like it a lot but I wanted an iOS solution for iPad. I may give it another try but it needs a good tutorial.

Developer Response ,

Thanks for the feedback, sorry to hear you are having trouble. Could you please email us with more details (you can use the Feedback link on the Settings page). To use PHRF Time-On-Time you would edit the Fleet and turn off the toggle that says Time-On-Distance. You also need to ensure each race includes the distance (in nautical miles). Our website at has been recently updated and has new guides. - Claire
