For smaller units it might work well.

Look at the "boom"set-up on the UFO. Remembered, not forgotten....(read the Pro Boat article as well).

Yessa, i expected this link.
thanks.
But, as one can see UFO's main has battens and is non- furling.

I' m wondering about the mechanic solution on the russion boat --rotating mast with fixes spreaders .
Any idea ?

Aah , eventually i got it.
It's a a simple rotating wire for furling behind the mast:

Same principle with A-mast:

The "forgotten" thing on the russian boat is the spar at the aft leech for max. roach AND furling.
With modern materials it might be a better compromise for cruisers ?
Perhaps with a conventional furling spar inside a rotating wingmast of little chord; eliminating the sag.

P.S.
