Hey. Great app, congrats. However, I was wondering if you could add a new feature. In many sailing races they give you bearing and distance from the starting line to the first mark in a course. That would be amazing. Also, if we were able to add waypoints by sailing through them it would be much easier to add the leeward marks. Thank you!

Developer Reply
September 17, 2022, NicholasFinch

Hi Carlos, Thanks for the review. If you are on any of the main screens, and click " BACK" you have the option to add a waypoint. You can then steer to the waypoint in the waypoint steering, and that gives you distance, and angle off the waypoint steering cues ( waypoint is 45 right ) for example. Or you can create a route with that waypoint and others.

September 12, 2022 | Version 4.91

I love it. I wish I could change the countdown to anything like we can for the wind and such. I like a 15 minute but it does 5 10 20 and 20 I’m not near RC yet and then at 10 we are too close to our start and already tacking around a bit. Also, update doesn’t have me pay. I’ve left it on all night for 8 hours, I have used the app a lot for short races. I have found what I need to do to make it come up, but I’m kicking the developer money anyway, it’s a sweet app and he deserves my $10 for making it for us!

September 6, 2022 | Version 4.91

Great and useful app while sailing!!! After a few months of using it I wonder if you could add some extra infos as: 1) average speed 2) battery percentage 3) use of map

Developer Reply
September 6, 2022, NicholasFinch

Thanks for the suggestions. The map is a bit of an issue because it uses a lot more memory, and the app running with all the Tacking, Gybing, VMG calculations and other that it does prevents a lot of watches from even displaying it. It would be limited to the same Map that is available using the Garmin Boat applications but with less functionality. You can message me, what average speed are you actually after? last 10 seconds, or minutes or legs, or since the race started?

Greta app! But after 5 hours no code on display and I still cannot steer course because the app shuts down … could you help me ?

June 14, 2022, NicholasFinch

Hi Nicola..... what version watch do you have, and are you saying that you never paid for it but the 5 hour message is not working? Sounds to me like something may have gone wrong when you installed it. I suggest uninstall and re-install, then turn it on overnight and leave it running, and in the morning you should have the payment screen with the link showing.

June 13, 2022 | Version 4.91

Great app for all kind of data driven sailors. Deep bow to Nicholas!

Developer Reply

Thanks, On your questions, Speed is Garmin derived GPS blended with other sensors. The difference between gpx and this is that GPS includes GPS positional errors where as I assume garmin try to reduce these. I don't think the speed is from satellite doppler either, because it appears to lag.

Thanks Manuel.. The Fenix 7 looks like a fantastic watch ! For everyone else , if you buy a new model watch that is not on the support list, send me a message and I will do some testing and add it. Nick

I have the Garmin Venu with only two buttons on the right hand side of the watch and can't seem to access the menu's. Is there a way to fix this?

Developer Reply
January 6, 2022, NicholasFinch

It should already work, either hold button A for two seconds, or hold button B to access the main menu.

Garth Wimbush
November 5, 2021 | Version 4.7.1

Nice App, well though out. There are a couple of changes that would help me though - the start button seems to also start the race countdown, but I would like to track the session before I start the race. Also, there are often multiple races within the same session, but I don't want to have to set the start line each time.

Developer Reply
November 5, 2021, NicholasFinch

Hi Garth, unfortunately the the two are linked together. I might * that is a might, be able to modify the countdown so that if you have a session recording started, it applies an offset to get you back to the race countdown screens. The issue some people will have is that if I remove the reset of start a and start b, and they do adjust the start line, you will have to stop and save the session in order to be able to reset the start line..... I'll try add something to the next iteration 4.8

October 7, 2021 | Version 4.6.0

Nice app, would be 5 star if the wind speed and angle are easily set (use buttons!) and isaff fixed time is added to the race countdown

Developer Reply

4.7 Update - Wind info can now be set manually using the up / down buttons / swipes as well as the existing wrist rotation method.

Árni Möller
September 26, 2021 | Version 4.6.0

Hi, 1. Can we expect in the future to be able to import waypoints and routes to the watch with a PC, It is time consuming as it is? 2. I agree that it is very difficult to set wind speed as it is today. Otherwise thanks for the cool app.

Developer Reply
September 27, 2021, NicholasFinch

Hi Arnie, You already can use a PC or a mobile phone if you use the Garmin Connect App or the Garmin Express app - but the waypoints must be input through the settings in my app. From Garmin express you can only create waypoints on the pc, but once the waypoints are entered the routes are very fast to create on the watch. In Garmin express, connect your watch to the PC, click on Apps, Sail Racer, Settings and enter waypoints from here. If you want to add more than 20 waypoints, de-select " overwrite watch waypoints" and that way you can add up to 20 click save, click "sync" your watch and then add another 20. The limit to the number of waypoints is dictated by the memory size of your watch. It may only become an issue if you are using a non pro, non x, non map, non music watch. Also - Only English is supported. French in particular will not work using the watch app or through the phone since they do not allow . in the decimal place / period.

Is it possible to have the app show VMC towards a waypoint?

Developer Reply
September 23, 2021, NicholasFinch

Hello, thanks for the review..... It already does show you VMG to the mark if you are on the waypoint navigation page. If you are on the wind page it shows you VMG into wind. I've got an aviation background so I don't use the VMC terminology. VMG is velocity made good to wherever you want to go( wind or a waypoint ).

Rob Schaap
August 19, 2021 | Version 4.4.0

I’ve installed and tried most of the other sailing apps that I can find but this is my favorite. I use the race countdown feature, I love the vibrating as it gets under 10 seconds…. While racing (or practicing a race) I will primary look at the VMG value, but I don’t rely on it as gospel since I’m mainly on a gusty lake where shadows disrupt the direction constantly. When I log practice races it’s a great way to compare my speed against distance. The other day when tooling around in open water I was just using the compass. My only complaint is that setting the wind speed is a pain. Tough to set and tough to really say… when the wind is 6 - 16 what do I put in anyway? I don’t edit the wind once set because I’m in a dinghy with no free hands.

Nice and feature rich app! Is it possible to add a tack to layline suggestion? Sailware has a really nice one implemented if you need any inspiration!

Developer Reply
August 1, 2021, NicholasFinch

Hi Fenix, If you are using a non-pro or non-X version fenix, then the app at present is running at maximum and cannot physically have any more features added. It will already give you tack and gybe layline suggestions ( is that what you mean? ) with the non pro and non x versions the angle is automatically calculated based on your best recorded tack or gybe of the session.

hello, how to access the polar speedy log?

Developer Reply
July 27, 2021, NicholasFinch

Hi, if your watch supports the polar log then go into the main menu and select POLAR LOG. Follow the instructions, for now - You need to plug watch into a PC, create a text file and copy it into the watch, then the watch will capture the data in a text file for you to get after the session. There is a plan in the works to make this automatic, so you visit a website after your session, but this is still in development. The instructions are in the last 5 minutes of the video on the App Info page" Sail Racer User Guide". If your watch has no menu for Polar Data, unfortunately it does not have enough memory to perform the calculations

This app is a must for any kitefoiler. It's absolutely perfect! It has everything I need. Love the VMG relative to wind. Love the speed focused screens. I didn't know how well it worked before I bought a Garmin watch but decided to buy one to give it a try. I definitely don't regret the decision. Only things I would add are double vibration feedback when I go above a preset speed and a different type of vibration feedback when I beat my session top speed. That way I can tell I hit the speed I've been wanting to hit without looking at the watch while going 34 knots and subsequently crashing into the water lol Also average speed last 15 seconds and last 30 seconds would be awesome! Average VMG for same time periods would be nice too. And having them reset when big angle changes happen; like when switching from going upwind to downwind or vice versa To summarize, knowing how good this app is, I wouldn't hesitate to spend the money to buy a Fenix 6 just to use this app. This app should definitely not be free.

Developer Reply
May 31, 2021, NicholasFinch

Good ideas....... on the top speed beaten... it's going to be annoying at the beginning of the session and going off for a while as you keep overwriting the top speed ??...... Would probably need a 3-4 second vibrate because it will be occurring randomly and rider might not be ready for it.. I might see if I can add it in the main menu as an option to turn on or off - default will be off. and I can probably put a filter in there so you could disable it below X speed

Great app! I use it mostly on 26 and 40 ft racing boats. Feedback: 1. back button exits app without prompting exit menu; menu would be helpful. 2. Wind speed: I would prefer to set wind speed with up/down button instead of rotate; it’s too sensitive. Point into Wind is perfect the way it is. 3. Race countdown; would be nice to be able to enter the minutes instead of presets or have both. 4. Map: would be great to have the option to view a map while using the app. Again, excellent app. Thank you.

Thanks for the review. 1. Is fixed in the next version(3.3.2), I'm waiting to finish one more modification before I roll it out. 2. I need to have a think about this one, It's probably a 1 or the other type deal. 3. I'm not sure about this one but will have a look into it.

great app for sailors (windsurf, kite & sailboat for me). Start counter includes time and distance (great !). A great addition for yacht racing would be Laylines management (all data is there). With the same simple logic as for WayPoints screens... Feel free to let me know if any help needed (calculation, features...). Many thanks !

Great app that does almost everything I’ve been wanting. The ability to change ‘VMG into the wind’ to ‘VMG towards a waypoint’ (VMC) would be a helpful feature for those who sail in a constantly changing breeze like me :)

Developer Reply

No worries - if you flick between the main screen ( wind ) , and the NAV screen ( waypoint selected ), you will do just that - change from VMG into wind, to VMG towards the waypoint

Excellent app, I use it for every windsurf session now! For the speed racers out there, would it be possible to also display the max speed over the last leg on top of max overall speed and current speed? Sorry if it’s already there I couldn’t find it.
