Hello, I watch this movie about 5 years ago. I think is horror moive.. Its about a group of friends which go with boat on island I think.. Then some people or vampiers, I don't remember exactly, started to kill them one by one... There's a bit shameless scenes, and I remember one girl that was blondy... That's all I can rembember.. If you know some movie like this, please tell me, and sorry for my bad english too ;) tnx

Could it be House of the Dead: House of the Dead (2003) - IMDb ?

Turns out the island a group of friends are going to was taken over by zombies.
