Customizing arcSail

Extend, customize and manage arcSail using these advanced features

Advanced Setup

Here are a few settings that will help tailor arcSail to support some of the more complicated race management decisions for your club. These features can be found under the "More" menu of arcSail. Some features require an in-app purchase to be enabled.

Setting up custom Boat Classes

arcSail is preloaded with over one hundred boat classes, including centerboard, keelboat, multihull and offshore classes from the US Sailing - North American Portsmouth Yardstick (NAPY) database. Each class stores its ratings from the NAPY handicap tables. These ratings are used to compute corrected times for open class fleet races. You are free to add additional boat classes and/or update the ratings specific to your club.


  • For each boat class, set:

    • The boat class name and type

    • Set a unique NAPY code

    • Set the USPN

    • If known, also add the Wind Handicaps for the class if known


Additional Boat Classes can be added at any time.

Importing additional Burgees

What’s a sail club without a plethora of burgees, right? arcSail comes preloaded with the numeric and alphabetic semaphores, but you are free to upload as many other burgees that you need to identify your fleets and clubs effectively.

  • For each burgee:

    • Download image of appropriate side to iPad photo gallery

    • Upload to burgee catalog by clicking “+”

Additional burgees can be added at any time.


Backup management **

We have provided the ability to back-up, restore and email arcSail databases so that your work is never lost and so that it can be transferred between iOS devices.

  • Under More, Backups:

    • You can determine the currently active database - it is highlighted

    • You can create a new, blank database by tapping "Add" and naming it

    • After selecting "Edit" of an existing database, you can:

      • You can rename a database by setting a new name

      • You can load a different database by tapping "Use Backup File"

        • The current database will be saved and the new database will be loaded

      • You can export a database to email by tapping "Email Backup File"

        • This can be kept as a backup or use to transfer to another device

        • To import a database into another device, simply tap on the file from the email client on the receiving device

** Backup management is enabled with an in-app purchase.

General settings

There are a few settings that help customize the arcSail experience for your club…

  • Under More, Settings:

    • Select “Confirm Deletions” to avoid accidental data loss

    • Select "Show Animation" to enable/disable the home screen animation (when disabled, your default club's "Home background image" will be shown on the opening arcSail screen instead of the arcSail animation)

    • "Penalty" applies to “Placement” or “Elapsed time” – used when determining scoring penalties.

    • "PHRF Time on Time Formula" is used in the calculation for PHRF ratings.

    • "Send Feedback" provides a mechanism to email us for issues (or accolades!) relating to the app.

These settings can be changed at any time - future calculations will be affected by some of these configurations.
