Terry (and Skip & Carla) - I saw this windshield the other day on a big (23-26') Shamrock that looks to be about same height as the one on the 21, although the sides are much longer than the original. (Very few modern windshields are as high as the original on the 21!) This one looks like the flat panels in front also open out like my Seafari which is a great feature for a Florida boat, but again is very rare on newer boats. Most new boats, if they have any ventilation provisions at all, just have little dinky side vents! All of these newer windshields appear to be of modular construction, so maybe you can find one similar to this one but with a center panel that folds over to provide the walk-thru feature.
