Vesper WatchMate XB-8000 smartAIS Transponder

WatchMate XB-8000 is the world's only black box transponder with built-in smartAIS alarms. Get alerted with the external audible alarm included with the XB-8000 that sounds if it detects a risk in case of potential collisions, dragging anchor or man overboard situations. The alarm sounds even if your MFD or mobile device is switched off. WatchMate XB-8000 is a Class B AIS transponder with a two channel parallel receiver and transmitter. It transmits your vessel position and details and receives the same kind of information from other vessels with AIS transponders.The AIS data is sent every few seconds and includes information such as course, speed, latitude, longitude, and heading. Static information about the vessel is sent every few minutes and includes the name, type of vessel, length, beam, draft, etc.


smartAIS features

Unlike normal AIS which send and receive AIS data, WatchMate Vision2 has smartAIS which is an active safety system with smart alarm logic that alerts you rapidly to potential dangers.

smartAIS includes these three powerful features:

  • Safety Underway. This alerts you when smartAIS detects a potential collision.
  • Safety at Anchor. If your anchor drags, smartAIS will let you know immediately.
  • Safety for your Crew. If someone is thrown overboard, smartAIS not only alerts you, it also provides their location so you can pick them up quickly.
  • It means you can focus on sailing your vessel, knowing smartAIS is always keeping watch in the background and is ready to alert you the moment it detects a hazard or unwanted event.

Collision Avoidance

CPA Alarm - smartAIS computes the closest point of approach and time until CPA. A CPA alarm is triggered if a vessel will come too close in terms of CPA and the alarm is prioritised by TCPA.

Alarm Prioritization - Alarms are presented in priority order of collision risk.

Bearing and Range - Computes the bearing and range to each vessel. Bearing can be displayed in magnetic to facilitate easy visual identification using your compass and binoculars. Bearings can alternatively be displayed in true degrees.

Guard Alarm - Sounds alarm if any vessel comes within the specified range. Both CPA alarms and guard alarms may be used together.

Alarm Profiles - Choose from multiple profiles according to the current situation (Offshore, Coastal, Harbor or Anchored) and the profile defines the distance notifications for alarms.


Anchor Watch

Every boater knows that being at anchor is no guarantee of total safety. In particular, anchors can drag without those on board being aware. Thanks to Anchor Watch, however, you can be safer and sleep well at night. That’s because Anchor Watch sounds the alarm if you drift outside a zone defined around your anchor position. Activate the anchor watch when you drop the anchor using either a wired switch or your smartphone or smartwatch remotely from the windlass or anywhere on-board.

Move Anchor Position - If your Anchor position needs fine-tuning after you have marked it, you can do that with the Move Anchor Position.

Breadcrumbs - XB-8000 plots your position in relation to the anchor and marks your positions over time for easy visual identification if you are dragging.


Man Overboard (MOB) alarm

WatchMate XB-8000’s Man Overboard (MOB) alarm sounds the alarm you the instant somebody goes over the side and activates his AIS MOB device. The Alarm clearly identifies the MOB on the display screen and gives you the location, bearing and range of the person for quick retrieval. It also provides continuous updates of position, bearing and range.
