AWI MANUFACTURERS
John: I'm assuming you are asking about Apparent Wind Indicators (AWI's). If so, there are any number out there and most can be found in the Boat U.S., West Marine, and Defender catalogs or on their web sites. I had a Standard Horizon AWI on my last boat (Hunter 31), but I understand they have gotten out of that business recently. Our new Catalina 400 has a ST-60 (Raytheon) system. Expect to spend anywhere between $650-850 for a complete system plus any instillation help you get. Good luck.Tim Leighton(S/V "MAGIC")
