We've used a lot of stuff for wind direction and boat speed over our (approaching) 50 year sailing life. I remember using a drag behind knot meter that would pull a plunger to approximate speed at one time. I truly appreciated the keep it simple attitude but I admit I am spoiled by the newer stuff (including GPS, which was not always around to help)
The windex has always been a part of it and I had the stiff neck to prove it. Having had questionable performance with the instruments on our new (to us) boat, we scrapped it all and installed a 9 inch Raymarine Axiom MFD, an !-70, and a new autohelm. I am amazed by the performance of this setup (I probably am jinxing it by saying that). It does way more than I need and I am still learning its capabilities. I still use the windex and lower shroud streamers but am finding I use the display more now.
I used the existing mast-top and hull sending units with adapters. It cost a few boat-bucks but it was money well spent.
