Raymarine continue to come out with updates to Lighthouse v3 that include new features and bring forward items from v2. Version 3.3 was released a few weeks ago, and includes support for older eS and gS series MFDs, Navionics Plotter Sync, and new features around radar and sonar.
Seattle and Elliott Bay is a busy marine location, and I am always looking for a better AIS system so that others can see me clearly. AMEC has released the B600 AIS Class B transponder with more than double the transmit power, and fast 5 second updates.
Having an AIS receiver on the sailboat means I can take that data and share it with AIS websites, as a base station. Doing that from a bandwidth-limited cellular connection creates some challenges which can be overcome with some scripting.
