Poco Loco- I think the molded Wesmac top has the most sloped back windshields of the DE boats, I think I measured their windshield at about 53-54 degrees. I believe the Calvin Beals are more straight up at around 65-70 degrees. I also believe the H&H tops are in the 65-70 degree range. On my 34 Calvin Beal I built the top myself and I think I settled on about 55 degrees because I wanted a sleeker look. In my opinion, that was a little too flat, which took up too much cabin space, etc. The flatter the windshield angle, the less room in the cabin you will have. That's one of the advantages of the West coast style windshield, the area in your cabin is increased, and there is less glare, they look more commercial, and the water runs off them way better.
So when I built my 38' Wesmac (I custom built the top for it as well), I went with 59 degrees and I really liked it. I personally think somewhere in the 55-63 degree range looks the best. Here is my Wesmac with a 59 degree windshield.
