I normally run a 2 man sloop crew and we have taken down quite a few ghost ships (galleons, brigs, and sloops). Heck, we even have done battles ourselves. I'm not sure if there was an update, but for the last couple of days the ghost galleons are just stupid hard. Mega-life (still just cruising around even when the bottom two levels are under water), cannon balls sniping me from a gazillion kilos away (I was sniped 3 times in the face from far distance in a matter of 20 minutes), every other cannon ball was a curse, and then when they seem to be slowing down, another one spawns right beside it.
Just, chill out. Please. Difficult is good, but this level makes the game unenjoyable, especially paired with your serial killer storms and volcanoes that killed me 3 times in one hour (just lightening, mind you).
EDIT: Okay, the volcanoes had nothing to do with our play session tonight. Just have an issue with volcano accuracy in general. Extra soap box while I was at it.
EDIT of EDIT: Don't take this to mean I don't like the game. I do! I like how challenging it is. It's just, when it's too much, it's too much.
