It is a really impressive vessel, however personally I would conceal the RHIBs into superstructure. And the HQ-7 faces wrong direction.
Considering the alternatives for better stowage of boats, at the moment alternatives are: side alcoves, storage on top, or on or near the stern (alcove).
Alcoves (retracting davits) left at the positions they are would cut into useful and important space (funnel vent paths, cargoway, hangar). If moved forward there is still front cargoway to consider and loss of crew island space.
Storage on top - too high in my opinion. But possible and there is lots of unused deck.
Off the stern directly - I want forward facing launching. Would flood if pooped.
Alcoves towards the back, under the helipad, but not open to the stern. Best option. More likely to be swamped than nearer the center. Loss of secondary personnel areas to the rear. Not as generally accessible.
Also there could be a ramp or a well maybe. But as to davits - San Giorgio class. - what other examples of large retractable tall davit setups are there?
Edit: updated and done. The overhang in the hull has to be overcome by over-sizing the alcove boxes wasting space.
