Triangle - What is the secret on the ship?

Chris Smith (Severance, Creep) has a new film called Triangle, it looks very good in a time twisty kind of way (I posted the trailer ages ago but it was taken down - not sure how long this one will be up). Melissa George (30 Days of Night, Dark City) is the star. You can catch it at the UK FrightFest on 27th August. STYD had the photo.
When Jess hits a seagull on a drive to the local harbour, little does she know that it is a harrowing omen of things to come. She sets sail on a yacht with a group of friends and already things are not as they seem - she just cant put her finger on why.

Her suspicions are heightened when the yacht hits a storm and the group is forced to board a passing ocean liner to get to safety - a ship Jess is convinced shes been on before. The ship appears deserted, the clock on board has stopped, but they are not alone. Someone is intent on hunting them down, one by one. And Jess unknowingly holds the key to end the terror.

Have a look at the trailer and let me know what you think is the cause of what is going on. I reckon it is some kind of Timecrimes thing.
