Room to work for 6 foot 2 sitting

I am slightly crouched, but hardly at all. This enclosure has plenty of working room and is small enough to heat if it is not TOO cold outside. Last year, the boat was full of dirt and some mold after the winter winds and storms. With this enclosure on top, which has plenty of ventilation around the sides, there was NO dirt at all or mold. Worth the effort to plan it and put it together.
