PassagePlus for Mac

From Wind Vector:

PassagePlus is a passage planning and navigation application aimed at the leisure boating market. It is compatible with the UK Hydrographic Office's ARCS, Land Information New Zealand's NZMariner and the Australian Hydrographic Service's Seafarer RNC electronic charts. Passage planning includes the creation or import of waypoints and routes and the input of tidal information. Navigation can be by means of an attached GPS or by traditional means such as bearing fix and dead reckoning. It also supports the detection and tracking of other vessels by AIS, and the ability to record a comprehensive history of AIS targets will be of interest to ship spotting enthusiasts.
