@Clearphish In the UK we have what is called Gift Aid. If you are donating to an organisation with Charitable Status, you can claim Gift Aid (you have to declare your residency address) and the charity then gets the tax back (https://www.gov.uk/donating-to-charity/gift-aid). I don't know if Windy is operating as a charity (see other post from this morning about Just Giving) but if they were this might apply.

If you have what in UK is called 'charitable status' you could set up a Just Giving (https://www.justgiving.com/) facility so that people can raise money for you by sponsorship (it is fun and makes the sponsoring idea very much easier, even though they do take a cut). I am about to do this for the RNLI in the UK. I would do it for you if you had this facility.

Are your wave models taking into account surface currents? I am about to sail a 47ft sloop from La Reunion to Cape Town and a serious consideration is the Agulhas current running down the East coast of South Africa from ~NNE to SSW. This reaches up to 2.5-3 knots and is reputed to exacerbate (severely) the steepness and height of the waves when the wind is contrary (S - WSW). Are any of your models taking this into account and, if so, which is going best to show this?

Thanks for continuing to do an amazing job!

In passing, any chance you might do an app which can pickup server data sent by email over a satellite phone? Windy is great, but the bandwidth required is huge and impractical to pick up offshore.

I think most of this has been said but just to reiterate, from a sailing perspective there is little point having the forecast along the entire route for one moment in time as clearly, for a journey of any length, the situation will have changed substantially by the time the boat (moving at 6-7kts) has got there! So it would be really nice if 'boat mode' by default showed the predictions along the route given a specific boat speed.

That said, I have now got the hang of the fact that the weekdays along the top of the table do not relate to the weather beneath (this was very confusing) and I can make predictions by shifting the bar around. It's a bit cumbersome, but nonetheless worthwhile and helping me guide my friends across the Indian Ocean.

The last request is that the routes be save-able! (if they are already I have not seen how?). It is a pain to have to keep re-entering multiple waypoints everytime I come back to the app!

Thanks for everything, this is the most brilliant weather program in existance!

PS I also just saw the discussion of changing the forecast as time progresses. This is definitely important. If youc an do this you are getting close to software like Weathertrack and Predictwind (the latter is brilliant but expensive).

@marekd Aha, just saw that you are going to 'add the option of speed of movement'! This would be very helpful. I thought I might be missing something because I could not find anywhere the option to set the Boat Speed, which is essential. At the moment it seems to be a very slow boat, covering 170nm in a couple of days? I am working with a yacht that is doing 7kn across the Indian Ocean and I have to work the distances travelled manually at the moment. Would really welcome the ability to specify the boat speed. Thanks for all your brilliant hard work.

This is a great question. I am currently summarizing WindyTY forecasts for a fellow sailor who is in the South Pacific by satellite email. He has only sporadic internet connection, so being able to dump WindyTY data into a offline app would be fantastic.

Using Safari browser on an iPad, your shortcuts to, for instance kite surfing spots now overlaps the New Snow forecast buttons (Next 24h, 3 days, 10'days etc) so only the Next 10 Days button is accessible.

This implies that the current data is actually a model, is that right? If so, why does it not also include a forecast? I have a friend sailing the Pacific and it would be great to know quite urgently!!
Thanks
