I'm not a huge fan of the wind at your back ability. I love it, don't get me wrong, it's just weird I have an ability to change the entirety of nature and its ecosystem for 5 minutes at a time.

I am still hopeful they add a rowing system.

For example you have a 4 man boat and the wind is against you. Get some friends to row with each additional person adding 25% to the top speed till you have a full boat of rowers which would match full speed with sail up and wind at your back.
Bigger boats require more people so each person would represent a smaller percentage of the total speed gained. It would be a cool game mechanic and give peeps in the boat something to do and feel like they are helping out and not just going "oh cool, did you see that?"

I wanted to ask this during the ama but couldn't be online at the time.
