Damn you Dr. Wunibald Kamm!!!
Your truncated airfoil (Foil E) for having very similar drag coefficients as our 'purist optimum' (Foils A, B, C) boattails.



Trek Madone (Kammtail Virtual Foil) profiles know their aerodynamics.

That all sounds less neat than the Sealander, where the trailer IS the boat.

PS :
Holzgas is wood gas for a gasifier car (or whatever you call them) , and the gasifiers also ended up on single wheel trailers.
