Very Doable
I've owned my Vision 11 years now, and purchased it a year old while I was on the Chesapeake. It came with a bimini, with standing head room. However, for early spring sailing, I wanted a dodger. I went to my local canvas maker and discussed options with him. For the summer in the Chesapeake, I wanted a dodger I could keep up to keep the sun off, but allow max airflow for the hot days. We designed what the canvas maker called a California dodger. The top was Sunbrella, but all the panels were clear plexiglass and were removable. I was tall enough to stand under while on the top step, but about 6" shorter than the bimini, to allow me to look between them while standing at the wheel.A year or two later I went for a winter sail with a friend who had a complete enclosure. On a sunny day, it could be 30 outside and 60 inside. I had my same canvas maker design and make clear plastic removable sides for the whole cockpit, and a zip in piece to stretch between the bimini and dodger. This has been the most useful purchase I've made to extend my sailing season. Other sailors would come to the docks in the winter to check their boats, and I'd invite them to go sailing. I was rarely turned down, and had many an enjoyable afternoon with new friends enjoying the water.The purist might scoff at this, but we passed several boats over the course of time with sailors all bundled up against the cold, who would invariably go in after a few hours cold to the bone, while we would be out in long sleeve shirts and sail all day.I have to admit, I haven't used the enclosure since moving to Atlanta, but it would be impossible down here in the summer without the bimini and dodger.My advice is to look at a lot of boats and spend some time talking to your local canvas maker before ordering them. You'll only be buying them once, but you'll be using them for a long time.
