Jason nods, though he honestly can't say how one would make a more stable vessel with a mast and everything. People had been sailing for centuries, even millennia, so surely it couldn't be that hard to figure out, right? If only they had like a model or something to fall back on. Maybe...maybe there was something in the library? Jason made a mental note to check there, it was one of the few places he hadn't really gone yet, but Aziraphale had mentioned there were several books there. Fantasy or not, there might be pictures or diagrams to find. Even an illustration would be better than just pulling from memory and hoping for the best.

"Thanks. I might hold off on doing that. I'm not much for sailing," he admits. At least, without Percy it feels strange. Percy was the one naturally adept to the water and could have kept even the most un-seaworthy vessel afloat for a time. Now, if they could figure out a way to fly the ship that'd be one thing, though he doubted they were going to be able to rig up something THAT magically powerful. Although, the mast would be at least a little comforting, "Maybe if we can get that ship with am mast made though...I could at least help with keeping the winds in our favor at least."
