Hmm.

1) I have no idea what you're trying to do there. Setting up the boat's condition with an EVENT would fix things. Remember that there's already boats in the game that you just have to place.. use the SET VEHICLE START POSITION command in the event layer, as an Auto Start event with a switch that turns itself off.

2) Google.

3) Project menu, Create Game Disk. (Save it to a folder in your desktop.) "Include Runtime Package in Gamedisk" if your friends don't have RM2K3, or if you saved any downloaded stuff into the RTP folders (NOT recommended). It'll be VERY large though, and it may not email. (I doubt hotmail will allow such a big attachment.)
