sails perpendicular to the wind for full power? my sailing experience is dated, but that does not seem to be right to me. Don't they want a lower angle of attack? is this a specific of square sails? maybe I am not getting it in the docs

Still, very fun!

I’m not a sailor at all my I just demo’d this for my dad who is. He had similar feedback

I need to sit down and do a sailing mechanics audit to find a good balance between arcade/realism, I think a beam reach is supposed to be faster than downwind. But my angle of attacks could be more accurate especially for upwind sailing?

Here’s currently how tinywind does it if anyone’s curious:

Have a look at these [1] polar diagrams for tall sailing ships. The radial distance from the center is the theoretical boat speed and the angle is the direction that the wind is hitting the boat, with zero on the nose and 180 from the stern. Each plotted line is the boat speed for a given wind speed. They show how the square-rigged ships can't sail upwind any closer than 55 degrees or so and are fastest on a broad reach (wind from just back of the side). You can also see how longer boats are generally faster, but a smaller boat with triangle sails ("Bermuda rigged") could easily get away from a big square-rigged ship by heading more upwind.

Interesting for reasons unrelated to TinyWind: What are the numbers on the left edge, boat speed in knots? Also, from what place and time is the technology on which these diagrams are based?

And what is this forum that unfortunately I can't read? Who made these diagrams?

This is really useful, thanks! I’ll be making a sailing realism pass next week and will try to update it to reflect the square rigging dynamics a little better

In irons should be a slightly negative number, since the wind drags the boat backwards at that point. Plus it will force the player to tack back and forth, which is a fun part of sailing. I bet A.I. can tell you the angle the sail ought to render at too (unless non-moving sail was part of the cartoon aesthetic)

[tinywind]

I did that simply for arcadeyness and feel but I’m not married to it at all

Giving the ship a slight constant forward moment felt nice and forgiving when testing, and user still has to tack back and forth to get meaningful enough speed to strafe a ship. But I’m definitely open to sliding the realism scale here

I would advise not putting "real wind physics" in the headline when that is not a promise you can deliver on.

There's nothing wrong with arcade, but when you advertise "real physics" people like me are going to expect, well, "real physics".

[tinywind]

Hi Tyler, realism and arcade-feel doesn’t have to be a binary thing.

My big effort has been finding tasteful compromises to keep a “real” feel but still simple enough to not be frustrating and put away the game. Hope this helps!

"Hope this helps!" has to rank in the top 10 cortisol spiking phrases of all time.

Realism and arcade are not exclusive but I also would say that the headline saying “real wind physics” is misleading. I was disappointed to see that real they are not.

[TylerE]

When you can sail. Square rigger directly into the wind, that’s 100% arcade.

You are of course free to make your game however you want, but false advertising doesn’t help anyone.
