Square D QO120DF SP 20 Amp 120 VOLT Combination Arc Fault & GFCI Breaker

Bought one on Ebay for my boats QO panel.
QO GFCI work fine with my setup which includes a gen and an MSW inverter.
The price of $26 was real good for this combination AFCI and GFCI.

Is there any interest in having AFCI breakers on a boat?
I also wonder how it will work with my MSW inverter waveform.

I currently use a Hubbell GFCI outlet to protect all my outlets. Plan is to use the QO120DF on that branch circuit. I can use the GFCI outlet elsewhere.

I might get another one for the Cruisair heat pump, would that be worth doing?

Right now have all outlets GFCI by Hubbell and the kitchen - galley on another branch Square-D GFCI breaker in the QO panel.

This is a new design AFCI, so should have been improved.
Claim is AFCI has saved lives and prevented fires from arcing wiring from loose connections and abraded wires, so why not also on a boat, which IMO, would be more likely to have wiring faults.
