As for your question . . . there are several caches that you can access by motor boats . . . you may have to run a search for them. Oftentimes you'll find the higher terrain rating (4 stars) means the cache is only accessible by water (although sometimes it may mean that the terrain is just wicked tough or you'll be putting on some miles via your own two-feet).
