Different canals to be used by different boats One can spend a lifetime trying to build the perfect canal that works for all boats and spans the longest distance over the most varied terrain. But, if one only has one boat to get through, and the distance is short enough, many people will just place a couple sticks of dynamite and be done with it. The most important thing is that the boat gets to port, not the canal. But, once in a while someone will notice all of the holes and try to build a more permanent canal. They'll save a lot of people a lot of time and may even make some money on it.
