XM Satellite Weather actually has nothing to do with this new product, but I mention it in the title because Baron Services is both the meteorological expertise behind XM Weather and the developers of the WxWorx software which can make that XM data accessible on a boat's PC. The idea of the new Quicklink is to provide XM-WxWorx-like semi-real-time weather beyond the North America coverage area of XM's satellites, and it looks like Baron is pulling a couple of rabbits out of the hat to do it...

Note, for instance, the Nexrad-radar-like precipitation mapping on the Caribbean Sea image below, even though there are no radars covering most of that area. Called Rain Rate, Baron generates it globally based on computer modeling checked against ground truth. Note too the real-time lightning icons, also very valuable for storm cell avoidance, which Baron also has world wide.  I didn't even know that was possible.  There are many more data set available, as suggested by the menu bar below, and it is all purportedly highly compressed, and selectable, so as to work over narrow bandwidth connections like an Iridium phone.  While not yet shipping, the new service is pretty well explained at this Quicklink site, where you can also sign up for a coming prerelease software demo.  Be warned, though, that the finished QuickLink will cost about $500 with a $100/month subscription.
