Unless you do some custom scripting, boats will stop at the edge of the water. They won't teleport to the other side. That is handled server side and the way to fix it will depend on which emulator you are using.
Obviously you may need to re-do stuff like spawns, decorations, etc. to fit the new map.
Make sure you remove or replace the DIFF files in the client with blanks, otherwise you will see little bits of the old map patched into various places.
Thats about all I can think of.
