This code is correct. It was as simple as that because with how it has been messed up twice, and the fact that I did completely revealed the numbers in the face of everybody, it was just for someone to figure it out.
So another door got unlocked... in this door, you did found out... the remaining number for the final door... you get back to the door, and the door is unlocked!
Now, in that secret door, you did find out what you were seeking for... a way to make the boat working again, this said gas which was so difficult to find. Now you put some in the boat and the boat is working again... now, to take care of this awesome cruise!
So, later on, while continuing enjoying your cruise, you'll notice that I come back with something... some glasses of water and juice... for some of those, it does have something special included on it, did you noticed some ice? What do you think it is? And on which drink between water or juice do you think those are? Only those which got a number within the first four ways can do a choice, make your guesses!
Also... soon enough, we're arriving at some sort of destination.
