Frequently Asked Questions

Preferably the I-VMS is mounted within the wheelhouse or a locker where it is easily accessible to check the status lights.

No. It can go in the wheelhouse, battery locker or out of the way. Unlike previous I-VMS that used satellite communications to send data to the shore, this uses mobile phone technology to send data, and this does not require clear line of sight to the sky.
