How does Nautics Sailmate work?

Sailmate is used with mobile applications and with route planning software, which is used by a browser over internet. The user has a Sailmate-account, and he logs into the account with his applications and with the route planning program. Users personal routes and points of interest (PoI) are shown in all devices, which are logged into the same Sailmate-account.

How much does Nautics Sailmate cost?

The application download is free. With the free version you can see the sea charts, you can mark personal PoI´s and see the service desrciptions of marinas. "Sailmate Premium" is a feature package, which is intended for navigational use. Sailmate Premium license costs €19,99 per year. When you have activated your Premium service, you will see your exact position on the map with course indicator and speed display and you can see marina maps. As a Premium user you can also plan routes using a browser and see your personal routes in the applications. Also, you can download the maps to the device for offline use. In addition, you can activate a "Scout routes" -content package, which costs €19,99 per year. This package includes descriptions of certain harbours, including natural mooring places and smaller village harbours, and a number of unmarked waterways, which have been explored by Turun Partio-Sissit Ry, a scout troop operating in Turku archipelago area.

How can I get the chargeable packages?

You can buy the chargeable packages in two different ways: Either as an in-app purchase at the setting-page of your application or at the Nautics Sailmate homepage If you choose to use in-app purchase, you will be charged to the card which you have submitted to the application shop (Appstore/Google Play). If you buy at the home page, you can use most credit- and debit cards, also Electron works. PayPal can not be used to pay at the home page. After a successfull payment the license is activated to your Sailmate-account and it can be used right away. Depending on your device type, in some cases you need to log out and log in again to your Sailmate-account to synchronize the activation to your device.

How long is the subscription of Premium or Scout Harbours and Routes -packages? Will it renew automatically?

The subscription period is fixed term for one year. The subscription is calculated from the day of purchase or from the expiry date of an existing subscription. At this time the subscription does not renew automatically, but you have to renew it every year, unless your payment agent offers you automatic renewal service. You can renew also before the previous subscription has expired, since the renewal will automatically extend an exisisting subscription period by one year.

I bought a license but it does not work - what should I do?

Apparently your device does not know about the license yet. You should try to log out from your Sailmate-account and back in, because then your user data is synchronized. If you accidentally bought the license to a wrong account, please contact Sailmate support at tuki(at), and we can move the license to another account.

How can I find out how long my subscriptions are valid?

You can see the expiry dates of your subscriptions at the settings page of your applications. The route planning software shows the expiry date at the user profile page (the top key down on the right).

What is the purpose of a Sailmate-account?

A Sailmate-account is mandatory to all Sailmate users. The account is personal to you, and only you can access it. We do not share the information in the account to third parties. If you log into the same account with all devices you are using, you have your subscriptions and personal routes and PoI´s in all your devices.

Can I use Nautics Sailmate in several terminals?

Yes you can. You have to log into the same account with all your devices, and then you have your subscriptions and personal routes and PoI´s in all your terminals.

How many terminals can a connect into one account?

A Sailmate-account is personal, and the usage of the account is limited according to fair usage policy. You can connect as many terminals to your account as you have in your personal use.

Can I download the sea charts to a terminal (offline use)?

The Premium-users can download the sea charts to the terminal at the settings page. The downloaded charts work well also without data connection to internet. It is highly recommended to download the charts to the terminal, because the data connection is often slow at sea. The charts are downloaded at the application settings page, and they use approximately 800 Mb memory space.

What are the user name and password of a Sailmate-account?

Your e-mail address is used as the user name of a Sailmate-account. You choose your password yourself when opening the account.

How can I change my password?

The password management address is You can also access the link from the -page ("I have forgotten my password"). If your browser remembers previous passwords, you have to either log out from Sailmate before clicking the link at the home page, or use the browser in incognito (private) -mode.

How can I find out which e-mail address I have used to log in?

The login-address is shown in the application setting-page. You can make sure that you have used the correct address by first logging out from your account, and then logging in again with the correct address. Make sure that you login with that address which you have used when buying the service license.

How can I change the e-mail address which I use as the user name?

At this time the e-mail address can be changed only by sending a request to Sailmate customer support to the address tuki (at) If your address has been changed in the system, you have to log out from the old address and log in again with the new address, so that the applications find your licenses and your personal data right. You can log out and log in again at the application setting page.

How can I know if Nautics Sailmate will work in my device?

Sailmate works fine in most commercial smartphones and tablets, but unfortuntately there is no straightforward way to confirm this beforehand. The easiest way to confirm this is to download the Sailmate Free and test it. In some tablets (e.g. iPAD) the GPS-receiver, which is needed for location, is installed only in those devices which are equipped with a SIM-card slot. If you intend to use location, make sure that your terminal supports GPS. Also, it is mandatory that your device can access either Apple´s Appstore or Android´s Playstore in order to download the application. Some Huawei´s models do not support this requirement, and unfortunately Sailmate cannot be used with such devices.

Why do I have to pay for Premium?

Subscription fees are the only revenue source for us, because we do not e.g. sell your personal data to anybody, and we do not show advertisement to you. One reason for the cost is, that in navigational use we need pay license fee for the sea charts to Finnish Transport and Communications Agency. But if you compare the quality of the maps and the value of the service for a boater with the other cost elements of boating, many users think that Nautics Sailmate is quite reasonably priced.

I am using the free version, but my position is not shown. Why?

Sailmate Free is used to see and browse the sea charts license free. However, we wanted to make the usage as easy as possible and the application opens at approximate location of the user. Sailmate Premium is intended for navigational aid, and it shows your location accurately.

How do I use personal PoI´s?

You can create your own Point of Interest by tapping the chart at the point where you want to have the PoI. A window opens, where you can name the point or write information, and then save or delete the point. With some devices you can also see the coordinates of a point and the distance to the current location.

How long the personal routes and PoI´s are stored in the Sailmate-account?

Your personal routes and PoI´s are stored in your account as long as the account exists. The Premium-level information you see if your Premium-license is valid. If your e-mail address changes, do not open a new account, because you would loose your data. Instead send a request to Sailmate support, and we change the user name address of an existing account (see "How can I change my e-mail address").

Does Nautics Sailmate work in Windows-phones?

Sailmate-application can unfortunately not be downloaded any more to Windows-phones.

How do you use the route planning?

You can access the route planning with a browser at the address and by choosing route planning. Alternatively, you can type the direct address to your browser address field. When you choose to "log in" you are asked to log in unless your browser remembers your credentials. The principles of the route planning are: - Two modes: routing along the marked channels ("väyläreititys") or direct routing ("viivareititys"), - You mark the starting point with a long press, then the point turns into a coloured mark, - Then you mark the waypoints in a similar manner, the software connects the points, - The route log can be seen in the middle key down on the right, where you can also give a name to the route and save it. After this the route can be displayed in you application. You can choose the route you want to see at the settings page of the application. You need a data connection when choosing the route to be displayed, but the chosen route will stay displayed also without data connection until the application is closed. Please make sure that you have logged into that account where you have saved the routes.

How do you use the track recording?

You can record your track and display it on the map. The recording is started with the record-key and is stopped with the stop-key. You can then decide if you want to save the track as a personal route for later use. If you do not save, the track remains displayed as long as the application remains open. The recording works only if the application is open and the device is not used for other purposes. If the device is used for another purpose, the recording is paused.

Do I have to be a Premium-subscriber in order to buy the Scout Routes -content?

No. You can buy the Scout routes -content package both at the Free- and Premium-levels. The scout routes are switched on/off in the app settings or route planning setting.

Does the Scout Routes -content package replace the printed Harbour Book or Route Book of Turun Partio-Sissit?

No, it does not replace a printed book. These are two different ways to use the information. A printed book format has many clear advantages, while mobile use is in many situations easier. We believe that most users will use both formats depending on the situation.

Does the Sailmate harbour data feature the same information as is available in other marina guides?

The marina data, which all users can see, and the marina maps, which the Premium-users see, are the same as in the "Käyntisatamat" -book ( Some of the harbours in the Scout Routes -content package are the same as in the Harbour Book of Turun Partio-Sissit (, but there are also other harbours and natural mooring places, which are not available in the book. Scout harbours are available in Turku Archipelago, Åland and Gulf of Finland. The harbour descriptions are currently mostly in Finnish - we apologize this, and we are working to introduce more descriptions also in Swedish and/or English.

Does the Scout Routes -content package include the same routes as the printed Scout Route Book?

Sailmate shows a part of routes of the Route Book on the screen, but there are also other routes which are not in the book. Other information of the ROute book like the red shallow rocks and the aerial photos are only shown in the book. Scout routes are available in Turku Archipelago, Åland and Gulf of Finland.

How safe are the scout routes?

All the routes have been inspected and should be safe in ordinary boating situations up to 2,3m depth, but the actual depth of the routes cannot be guaranteed. The Scout Routes are unofficial, and they must be used based on visual observations and with care and with low speed. Outside the marked routes the depth information in sea charts is often inaccurate. Remember, that the master of the watercraft is always responsible for the safety of his crew and his boat. If you experience suspicious depth situations while using the scout routes, please inform us immediately at e-mail address and we will figure it out. We appreciate your feedback!

How accurate is the position in Sailmate?

The mobile device of the user (phone/tablet) determines the position of the vessel to be shown on the chart. The accuracy of the position depends on the quality, features and software of the device. The position of the device in the boat, the changes in the orientation of the device and the time used to track the location satellites can also affect the location result accuracy produced by the device. In normal use the position is usually accurate enough to be used as a navigational support, but Sailmate does not replace a plotter, and the real position of the boat must always be verified by a marine plotter and by visual observations.

Can I cancel my subscription if I am not satisfied with the service?

You can always cancel your subscription in reasonable timeframe. We at Sailmate can refund you if you have made the purchase either at Google Playstore or at web-page. We cannot unfortunately refund if you have used Apple´s Appstore, but you have to request a refund yourself. If needed we can provide instructions. Please contact tuki(at)

How can I get help?

We help our customers by e-mail. If you need help, please write a message to tuki(at), and we respond as soon as possible. You help us to give a more useful answer, if you write as specifically as possible. Please also tell what device you are using. If you do not see a response, please check your junk mail folder. We do our best to serve in Finnish, Swedish or English.
