[A faint smile is given toward Raph, transitioning into a more lopsided one once the subject of ship sailing comes up.]

Well, Viking ships are usually long and thin. They have shields lining the sides, maybe one or two separate sails to a mast, and a giant rudder in the back for steering.

Half of the time we use oars, but with that many Vikings to a ship, it's no big deal.

[They'll have a problem here, but maybe they can wing it.]

From what I can tell right now, the rigging looks about the same. Where's the rudder?
