Equipment to sail a catamaran and a trimaran : GPS/Plotter
Nowadays, who would dare to set off round the world (or even round the bay) without a GPS/Plotter? No one, of course. And with the new tools being offered by Furuno, this is even truer! The 1670 or 1870 are powerful and fast, and with the C-MAP 4D charts, will even allow you to navigate in a 3-D relief environment.
