Now that you've mentioned his hair is a mess(t). I guess the reason is something around "no one will pay atention to him anyway as all of the main guys are together so let's just keep it like this".

About the Dragon-Slayer friendly ship I guess it ties in with the question Carry and ak raised. Why did the Raijinshun join BP exept because of convenience? I guess it will be explained soon but my best guess is that they joined exactly to start the preparations for an eventual conflict. More than anyone else Laxus would know that Makarov wouldn't disband the guild without a trully serious motive nor would he ust disappear like he did. He made his own research and found out of the threat from the west continent ans stated preparations for an eventual battle by allying himself with BP.

Christina is a great tool for battle and knowing that Ishgar have a good number of DS mages Laxus asked them to make some improvements so that their main powerhouses wouldn't be strained by their critical weakness. About how you make it DS-friendly, there's the scientic possibility that it just erases any sensation of movment, like if the ship is stationed, or the magic one where there's a permanent Troia aura inside it that cures staus ailments like Wendy's magic.
