That's a "Plätte", a local kind of boat that's been used for transportations or by fishermen in the days of old, nowadys, there's a more touristic factor to it:
I somehow doubt that Obertilliach will be the villain's lair. Nothing there really looks like a villan's lair. They're building a simple house that basically looks like a large shed and (from what I heard) some smaller buildings (which really seem to be sheds) nearby. And all that in a tiny remote Austrian village. Okay, we did have something like that in OHMSS, but I doubt they'll repeat that (or a hollowed-out montain, for that matter). People who've been there also doubt that there'll be a huge explosion in the scale of Skyfall, because the village and some of it's buildings are much too close. Of course, there still the option of CGI...
My guess: We'll get that plane crash that's already been mentioned. People on that plane may die (but it may as well run on autopilot), but it'll be about the people in the house. And I supect that it'll be some kind of Hannes Oberhauser character - if not himself - and maybe his family. Until now, I've not been a fan of this Oberhauser theory, but I've done a bit of research. If you look at the other Austrian location, Altaussee, it certainly doesn't ring a bell immediately. But the bell rings, and loudly does it ring, if you look at the map and see that famous Lake Toplitz is in only a few miles distance. Which could mean Nazi gold and/or all other kinds of secret Nazi stuff, thus pointing us straight to Oberhauser.
Altaussee, Altaussee, Bond movie's gonna be shot at some lake in Austria, nobody really cares because nobody really knows. But if someone would have said "Theyre shooting within five miles of Lake Toplitz", we'd already be speculating wildly for weeks. I'd say Austria won't be villain's lair, and it won't be the climax. PTS with the killing of Oberhauser as Bond's motivation (hey-ho, this time it's personal... again) is my guess. Could even be a backflash, as that plane crash may have taken place years ago. Wouldn't be too surprised if we get to see images of some vintage plane, sooner or later.
Rehearsals and test shootings in Obertilliach will take place in December (1st until 19th), principal shooting there is scheduled to start with the new year (03rd January, I've heard, but that's a Saturday), until mid-February.
