Google Maps needs a boat

http://goo.gl/maps/J5sC

Probably not a huge use-case, but it'd be neat to the sailors and boaters among Google's audience to be able to explore maritime routes. The example above is pretty much useless unless you are going to walk and then swim. If you have a sailboat or power boat the approach would be different as well (tack-ing vs. straight-line routes).

Call it a "feature request".
