Really? solid pieces like motorboat's hull? That's dissapointing.
I used to make sizeable airplanes and ships out of legos. The biggest one had a span of about 3 feet. Took some effort to design the wings in a way that those would stay intact while still maintaining a slim profile. Better yet, I could have rebuilt it out of the memory, like most of my lego structures.
Just couple of hours looked at an advertise leaflet's back page when I picked it up and there was a lego police station. It looked pretty much like police stations 20 years ago, just with more additions to it and some newer gadgets, like a boat and two cars instead of one. Lego sure seems to be boosting it's marketing world wide before christmas as everyone suddenly has memories of the legos.
