The object name for any spawn point is entpnt, just set the Object Type to Boat Entry for a PT spawn. If you are placing more than one SP from any field set the SPs' ID tags to a different number for each, so 0 for the first, 1 for the second and so on. The 0-tagged SP will appear as the "H" button in the game. Also rotate the arrow on each SP to match its direction from the host field.
