Except there should be no corners on this boat tail. All the "sides" of the boat tail will be rounded (think: more of a cone than a pryamid, so will need some kind of framework to support the shape. Correction: there will be hard edges where the boat tail terminates at the "transom".
Christ: the chicken wire idea to support fabric is a good one. But I decided against fabric because chicken wire or the supporting "tent pole" framework to get the polygonal "resolution" I want will be as bulky for storage or as much work as doing coroplast surfaces, I think.
Anyway, here's all I have to show so far. Should have enough length here to go almost to a point if I want to take it that far. (But I don't plan a point - it'll have a flat rear surface to mount the lights/licence plate.
