I've updated the map to improve the functionality of the boats as well as the following:
-larger boats with a ramp to the top
-no music, it bloats the filesize.
-on-screen text to tell you when your boat is moving
-improved trigger logic for boats
-all water is safe to dive in and teleports you unless "Lots-o-Crocs" is active
-other small fixes, too numerous to mention
try it and let me know what you think!
