The front vinyl stays zipped along the top and pulls back & up to the arch so the wind doesn't bother it and at 30 mph the screen does fine. We had the valance made an inch longer to accommodate 1" wide Velcro. The entire perimeter of the top as well as all the vertical laps have Velcro along with the zippers. This keeps everything tight even when the wind picks up.
A walk-thru windshield would be nice. The cabin door is centered with the head to port and the entrance to the rear berth to starboard. During warm weather when the side curtains are down I can stand on the helm seat and step onto the starboard side deck very easily. When she is closed up I have to step up on to the port side deck at the rear of the cockpit. If I have to tend to the anchor the Admiral has no problems maneuvering the boat.
