I like your optimism
Two weeks from factory to dealer is requiring all for the stars to be aligned for you. Depends on boat scheduling and whatnot but if the dealer takes delivery in W51 you've got half a chance of getting it in W52. But don't forget that dealers are on skeleton staff over Christmas and the PDI staff might not be working. It might be worth checking with your dealer on how they think they're going to fulfil their promised timeline
