Too new to understand this offset propeller shaft design?

As I look through listings trying to get used to subtle design differences sometimes something pops up that is completely unique to me. Here's one I haven't seen and am wondering what the purpose is as well as what negative affects it causes.

So date wish... what does the modern era begin? Would be the introduction of GRP hull? The core hull?
Is there a boat or a designer that marks the beginning of the modern design era?
There is no hard date. There are milestones that mark progress in yacht design and construction. The modern era is right now. The further back in time you go, the further you get from "modern". 30 or 40 years from now what we consider modern now will be considered "classic" and obsolete, because yacht design will have progressed beyond what we have today. That's not to say today's designs will be no good, they just will no longer represent what is considered modern design theory.

Certainly GRP is a major milestone, and it has withstood the test of time because it is an excellent material, but even that technology has progressed in both the materials and how they are used. 40 years from now we could be using carbon nanotubes in boat construction, who knows!

Fin keels are another development milestone that has persisted for decades, although keel shapes have evolved.

Another major milestone towards our modern era would be computers, CAD and computer modeling vastly accelerated hull and foil design because designs could be tested and refined without the need to build expensive scale models and tank test them.

My 36s is going to be 37 yrs old. The design evolved from the 35 which is from maybe the late 70s (guess).. making the design over 40yrs old. They changed the transom. I consider my boat neither modern or classic. It has a teak interior which you don't see in new yachts.. as they attempt to make the interior light and cheery I suspect. Old interiors were much "darker" in residential architecture than in modernist architecture. Wood is an old material not a modern one I suppose. Plastic is fantastic and low maintenance. Remember the line from the Graduate...


learn to love your plastic boat... Material tech marches on...

Soon the diesel will disappear replaced by a light powerful electric.

Ah, very enlightening. I'm so glad I asked.
And I shouldn't have described it as a "design flaw" in that post you quoted. I never did think of it that way. I don't know enough to think of it that way. I figured at worst it was a compromise like much is in marine design I guess. I was only making a tongue in cheek reference to the job marketing departments have of turning everything into a feature.
