Yes, the manatee can "get out of the way" IF it detects an oncoming vessel. Manatees while normally slow can move at 21 feet/sec or 14+ MPH for short distances and can continually travel at 4-5 MPH for extended periods.<quoted text>
I don't care about the manatees because there is nothing I can do to save them. I just don't want usualthe usual bunch of idiots running wild along our waterways at high speeds.
Speaking of which the slow speed is for the boater - not the manatee. Like the manatee can get out of the way or something.
A vessel travelling at 4 MPH cannot be heard by the manatee until it is ~ 12' or 2 seconds away. A vessel on plane can be heard ~ 560' or 16 seconds away. This is based on empirical test data collected in Dr. Edmund Gerstein's research in Brevard County waters.
Gerstein has developed an inexpensive manatee alerting device that can be installed on vessels.
Manatees and boats can go exist. We need only to apply some existing technology.
