I can pay the captain 1k gold and say that i want to go to skellige, but 5 seconds after the video starts the game will crash without an error. Tried it since yesterday but now im out of sidequests ...

if there was some way to skip the video i might be able to go there but i cant find out how... pressing space or X on my controller wont work

Can anybody help me? =P i want to play but i cant because of this bug :(

Well, i can't help you but i have a similar issue.
When 1.04 hit, i was in Skellige, and i couldn't get back to Velen. Fast travel would just crash me to desktop. Now, i reloaded an earlier save where i was in Velen, completed the main quest there, and wanted to try to see if the fast travel from Skellige to Velen is still broken. Turns out, now i can't travel to Skellige. Same CTD as yesterday, but the other way around(which trip i was able to make yesterday).
So, at least i can say, you are not alone with travel issues. At least i'm assuming the root of the problem is the same.

Dunno how but today it worked. I raised the grafiks and suddenly it was no problem, but i dont think it has something to do with that.
