Overall it seems like a good patch, liking the windshadow feature, though it may be overdone (perhaps not reality wise but for gameplay sake) a little bit.
Now that it's basically impossible to determine whether or not you can penetrate a mast due to so many variables (woods (seasoned, regular, super rare woods), upgrades (mast thickness / penetration upgrades), sail settings (slow / half / full), ...), I think the hit counter "mast" when you hit the mast should only occur when you actually penetrate the mast.
+ I still think the rare woods buffs are OP, a fleet of ships consisting of +35% HP and similar other stats, result should in most cases be obvious, which is not ideal IMO.
Also, as said before in this thread, it should be impossible to disable survival if your ship is not equipped with the fireship upgrade
