Freebeard, yes you did…
...you’ve discovered my 2>3D side not kicking in.
I remember looking at your boattail and thinking taillights, rearview camera & ladder. Still am, but if the top of the boattail can be a less steep angle...er tangent... down. I think I need to build a scale model as you did.
Attaching anything to Moby without drilling holes ...at the bumper?
Actually your “scalloped” edge has me thinking. Attaching using the screw shear in the side of Moby, not through the back ie, pulling straight out on the screw. Its all fiberglass skinned, with a steel frame in there somewhere.
Aerohead, I know I was the one with the inflatable youtube...but the already bad experience with the awning being ripped off in a crosswind & plus Moby’s ladder location has had me scratching my head with the inflatable boattail... concerned about adding a parachute to the back. But you’re correct, its much more forgiving than “jungle gym”(trailer-Tail, but not Orbywan's?). What ever it is, I need to keep it light & strong, flexible & forgiving.
BTW: Moby’s long overhang is 9 feet ...from aft of rear wheel to bumper end there is a 5” rise. -Diffuser angle 2.65*
..there is 21" ground clearance at trailer hitch - Departure angle 11*
