You'll not get into Cayo Largo Marina with an 11' draft
, indeed I doubt that you'll even get close enough to the island to gain much shelter from it at all, so that's only going to be an option for light/settled weather
Whilst you will find ample depths to enter and anchor off both Cienfuegos and Santiago, I doubt that you'll actually manage to moor up in either of the marinas
Manzanillo too is going to be an anchorage only (perhaps 3/4M offshore) with 11' draft, you'll also get into the bight off the west side of Isla Juventad and around to it's north side too (don't go too far south down the island's east side) from there you should be able to scrape through the Manteca Passage
into the Batabano Gulf, though you definitely won't make it through the Canal de Rosario to enter/exit it further east.
In the far west you'll be able to anchor in the Bahia
de Corrientes off Maria Gorda, or the bay beyond Los Morros to the north of Cabo San Antonio; once again, both can get uncomfortable in rough weather
