The other same hull does have a Mumm 30 spar & fly's MH kites with no issues.
Guess it depends on how heavy & stiff your hull is as that loads up the spar.
June 2022 has J9 on he cover & test sail with Al Johnstone aboard.
That boat was quoted at $160,000 "as equipped" It had the electric IB but no sprit for assy. Kinda pricey !
