We had the very same concern. Saw several boats with fixed arches, and found it would be almost impossible to convert them to folding. Its easy to see if one is 'foldable', as you can see the stainless 'hinge' at the base of the arches. The boat we purchased (1988 CHB Present) has an arch/hinge that folds either forward or backward. And the dinghy crane easily comes down with only one large pin to remove.
