The possibilities are endless; just think a bit.
Construction of sailboat... what about the speed that the main sail goes up the mast when the bottom edge is a given amount of distance away from the haul of the boat?
Personally, I think the mechanics of the boats trajectory are important during construction. You can measure velocity and acceleration of the boat given an equation of position dependent upon time and mass of the boat.
How about some optimization? Suppose you would like to minimize the amount of surface area for the bottom two feet of the boat?
Hope this has helped!
