Not needed to compensate for no backstay. No modern production cats I can think of have significant mast
rake (certainly not as extreme as the Deans) and none have back stays. No backstay is necessary with the typical "tripod" arrangement of the standing rigging
on a typical modern cruising cat. The side stays are far enough aft and outboard
that the mast
is supported just fine with no backstay.
The only cruising cats I know of with backstays
are much older previous design generations of cats (like the Solaris I was on recently).
I think the most plausible reason discussed so far is simply to get the mast step more forward to increase deck
house accommodation spaces. If so, then a bad compromise choice I think.
For example, I'm out on charter
running a Voyage 50 this week, big deck
house space, no crazy rake in the mast, no backstay.
