Joining a crew
 

When someone asks you to join their crew, and you say yes, then what do you do to get on their ship?

whenever they launch their ship it will notify you. you can then go to any dinghy and when you hit shift, and get to the launch screen, their ship will show up. crews only last for the time period you're both logged in however. so if you want to continue to play with them you need to friend them.

Thanks for the info. BTW...sounds like my kinda pirate.

Also you can click on crew in your friends list. When you captain has boarded, ship will appear as a button next to their name, and you can click on that.
