Equipment to sail a catamaran and a trimaran : Man Overboard
In the event of someone falling overboard, your catamaran itself is the best chance of survival.
Those still on board need to know
as soon as possible so that they can get your position. That's the idea
with this beacon which once activated, will send a signal to each one
of the AIS, set off a catamaran onboard alarm, and indicate the exact position
thanks to the integrated GPS. www.oceansignal.com
