Rapscallion, Beauty is in the eye of the beholder, but keep in mind that Nol extends a very long Dutch tradition of small sailing boats. He blends very well their typical silhouettes and modern technology.
The Wantoo folding beam mechanism is innovative and makes a lot of engineering sense if one commits to a folding proa. This is more challenging than folding a tri, but could be easier than folding a cat. It may not be easy to give it a spiffy look but I doubt the windage of its tube lattice is worse than cat2fold or single tube beams if one considers that for safety railing & stanchions should not be "forgotten" as is done all too often. Offering a choice of Wantoo folding and fixed beams is possible, but I doubt it is worth the serious extra trouble to engineer the end rotating fixation points to be readily removable.
