There’s some game file leak going around the internet that shows a feature called “Change Village”, so it’s hard to tell what it will be the only thing that’s sure is that it’s going to be HUGE!
I’m willing to bet that the ship will allow you to switch between two villages you own/manage. You click on the ship, and “sail” to your second village to play it.
Lots of people already have two accounts (e.g. a mini) on CoC, and its annoying to switch between them on a single device. SuperCell would obviously want more people running two accounts, because they will be more likely to buy and spend gems. It would be a major advantage to both the players and SuperCell to streamline the switching/management of two villages.
And if you look at the leaked game files, it make sense. There is the “change village” feature leak, which is probably what actually implements the switch to your second account. There are two sprites of the ship, one with the normal ship and the other with the broken ship. This is probably going to be the same as the clan castle, where the ship starts off broken, and to enable the “switching” feature, you have to rebuild the ship. It will probably have a minimum TH level required to rebuild the ship.
The ship icon is probably for a game setting where you specify what the second account is that you want to link.
You heard it here first
