Great, thanks for the feedback!
I understand very well that it's not easy that many things are already well fixed.
For the masts that move it could be the same mechanics as the sails no?
In Ahoy's discord in the "other-games" section I posted pictures of the frigate l'Hermione using the staysail.
It is not always used but it is still useful, it is a powerful sail.
Lowering the yards reduces the power of the wind in the sails. When you arrive at an anchorage, you can do this to slow the ship down. When you want to be overtaken by a slower moving ship. When you have to bringing.
Very good for the anchorage! I hope you can put it on.
