Welcome to my free collection of tools navigation and mapping tools and other online boating services I've developed.
Chartplotter is a chart plotting tool for planning and sharing sailing trips using Google Maps. Enter waypoints by simply clicking on the map or by entering latitude/longitude coordinates.
Chartlayer is a tool for overlaying images on a Google Map to create a geo-referenced map for use with chart plotting tools, such as OpenCPN. Simply enter a URL for any chart image, then adjust the bounding box so the chart is aligned on the map.
Marine Radio Frequency Quiz is a tool for learning marine radio frequencies, which I wrote when studying for the Marine Radio Operator's Certificate of Proficiency (MROCP).
Wind pie is a simple tool for making pie charts of wind directions. For example, the wind pie at right denotes protection from winds N through SW.
Anchorage Finder is quick way to look up information I've published on South Australian anchorages.
KML Tools is a collection of geospatial tools for generating and converting KML and DXF files used by Google Earth, Google Maps and CAD tools such as Sketchup.
Boat Alarm is a free service to monitor shore power and batteries on your boat and send alarms by email.
