I added a DMK 11A-GPS multiplexer to my Seatalk network and now I have an app that displays all the old Raymarine sensors on the boat such as Apparent Wind Speed, Apparent Wind Angle, Tempature, Depth, Boat Speed, Heading, etc.... The DMK Analog Engine Monitor is on it's way. This multiplexes Seatalk, NMEA 0183, NMEA 2000 sending it over wifi to the iPhone/iPad.
