PassagePlus is a passage planning and navigation application aimed at the leisure sailing market and is intended for the day/weekend coastal sailor. It works with the UK Hydrographic Office's ARCS charts and Land Information New Zealand's NZMariner charts.
It has an uncluttered interface usable on a small laptop like a 12-inch iBook and a feature set restricted to those things that might be used frequently by this kind of user.
Version 1.11.3:
* [FIXED] Fixed bug introduced in v1.11.2 which caused the degrees symbol to be shown as the infinity symbol instead.
