Many imagined driving to a river and rowing from there if roads become impassable only to find it impractical. You can't load much in a boat, repacking takes time...
If you have already packed motorboat in a dock or live so close to a water you don't have to drive it can be good option
On the funny side i remember one episode of Doomsday Preppers where deluded newbie family had the idea of switching cars to canoes only to end up behind schedule and in total chaos
