stability wise it now works. now a few more comments:
- the funnel is waaaay too big for the installed power, unless you have gas turbines on board, which I suppose you have not, for an OPV.
- the bow thrusters are in a quite bad place
- the anchor looks flimsy compared to the size and shape of the vessel. I suggest stealing one of an similar ship
- the funnels block the I-mast partially.
- those marlin mounts are in quite a bad spot, you need increased beam for them while they have no line of fire to the back.
- you have no gun line of fire to the back at all, which seems not to be an good idea for an vessel that needs to come relatively close to 'enemy' vessels, as an OPV does.
- the helideck seems a tad big, you might be able to use that space more effectively and thus not needing that longer hull
- the crane is a bit on the big size for that RHIB, I suggest splitting the cargo and the RHIB handling (or using the crane you first had, which is an very good multipurpose crane)
- the Mk 29 NSSM launcher is, IIRC, an outdated drawing of the system. you can find the newer one here:

- on a sidenote, why do you have NSSM on an OPV anyways?
my suggestions would be:
- make the hull L*B*D: 100*16/17*5 on the waterline
- bring the main deck down 1 or 1/2 deck (thus lowering the light grey part of the hull)
- make the funnel 1/4th of the current size
- make the bridge as wide as the funnel
- move the marlin mounts to the centerline, or on the 'corners' of the ship (fore and aft to the sides) so you cover 360 degrees
- lower the main gun one deck
- keep the mast, bridge and hangar in the same position (at least, when compared with the main deck, which you will lower)
then, you have, IMO, an quite sensible vessel!
