sail OPYC

O.P.Y.C* is a sailing game using a physics.

The navigation simulation starts from the basics:

  • The pressure the wind makes on the sail cloth
  • The forces on wet surfaces: keel, hull and rudder.
  • The impacts with waves and other floating objects.

All this physical interaction is computed locally on your device CPU.

Connection to the Old Pelican Yacht Club Server gets you:

  • real time winds ( realtime values extracted from NOAA GFS weather model )
  • records your navigation activity ( track and sailing vars)
  • rewards from free sailing and race participation.

OPYC app is available for iPhone/iPad, Android phones & tablets and Windows PCs.

Boat registration is done from within the app. Use boatname/pass code to login on a new device.

Your OPYC boat will only move when sailed on the app. If you click the home button and change to another app, like to answer a call, your boat stops. In other words, the boat is not moved by the game server.

Sailing a OPYC boat is not entirely pointless: You earn OPYCoins ( our own crypto currency ) by crossing gates around the world and by participating in our busy schedule of OPYC regattas.

To start sailing, get the App from your app store ( iOS, Android). Windows version download from our web.

User registration is required on first use.

About OPYC

OPYC (Old Pelican Yacht Club) is a sailboat simulation mobile app, using physics.

Real boats move because the wind presses against each little piece of sail cloth. Waves and floating objects can hit the hull. Rudder action generates lift that corrects the boat course, but also generates drag that can hold you back. Keel forces prevent sideways movement of the hull. Sails can be ripped by strong winds. Chinese jibes can happen during the night.

In order to get this kind of realism, boat computations had to be moved from the game server, as in most other sailing games, to your device (phone, tablet or PC). This was a bless, for no server can handle real time physics simulation for a large number of boats. Not really scalable. At least our server can't.

Battery warning

Real time simulation calculations can heat .up your phone, and impact the phone battery. Have a charger handy.


Sailing in the app is the only way to move an OPYC boat. Boat teleporting is only allowed when you participate in a regatta.



Is this a regatta game ?

Version 2.5 introduced race events. There is a busy schedule of races. You can schedule your own regatta and invite friends to participate. A choice of venues around the world is available, with course sizes and wind conditions.

What do I get ?

There are gates at selected points of the world. Cross gate lines and earn OpyCoins, our own crypto currency.

By participating on regattas you also earn OpyCoins.

Do I see friend's and the competition boats ?

Boats within AIS range (30 NM) will appear in your chart and in the simulation window.

Also boats participating in the same race.

Will this app hog my cellular Internet?

The app exchanges a small package of data each couple minutes, with very little bandwidth consumption. Uses wi-fi when available.

Can two or more people play with the same boat ?

Only one device can be active at any time. The device that logged more recently has the valid token, and is allowed to talk to OPYC server.

Can I play from the web browser?

No. Only from the mobile app.

Is OPYC available for desktop computers?

Yes, for Windows PCs. Also available for iOS and Android devices ( phone and tablets with good CPU recommended )

How long can I be off-line?

After a while without access to the Internet, wind goes to zero, so your boat will stop.

Does the app run in background, so I can answer a phone call?

No. If the app is terminated or paused, the simulation is stopped. Your navigation will resume from where it stopped when you last left the app.

Does the boat have autopilot ?

Yes. Autopilot is helpful for you to have a life. Just click the [Auto] button. This locks to the current course. Click again to lock the wind angle. Click a 3rd time to revert to manual.

The auto pilot works most of the time, however it can go unstable, if the wind is too strong. Make sure to use the proper sail.


What happens when I click reset button ?

Sails are reset, the boat is moved to the last known position and anchored. You loose the last 5 minutes of sailing, at most.

When the boat is anchored, you may turn it with a finger. Choose a sail and trim the sheets. Then click [Release] the anchor to start sailing.

How do I setup my boat ?

When you start the app or reset, the boat is in anchored state. In this mode, you can orient it with your finger, choose initial course, sail and set sail sheets properly. Then let go the anchor ( press Release ).

Control the boat and point to the desired course. Press [Auto] to lock in this course.

Steering by hand is better ( faster ) then Auto-pilot. You may steer by tilting device [Optional]
