Question: In [Triangle](http://www.imdb.com/title/tt1187064/), at the start when Jess arrives at the boat for the "first" time, is this the start of the continuation of the ending scene?

It's known that the cruise ship and any surroundings after leaving it is in a time loop.

Though Jess remembers the ship and tells Greg, she makes no indication that she is in the time loop. So yes, the movie was meant to confuse the user. But seeing that, according to the number of dead Sallys on board, the time loop occurs more than 20 times.

So, the first time she entered the loop, the storm sent her into an alternate reality with the never-ending time loop? Is this what the movie was showing? I noticed there is a deadly Jess that was not really in the foreground that got shot in the head, and stabs Sally and Downey in one of the rooms. I cannot really place where she falls into the picture seeing that one of the previous Jess instances killed that Jess instead of letting her jump overboard.

So is there a separate timeline/reality?

Answer: 
Not the way I remember it. The way I see it Jess is in a kind of purgatory, as the end of the movie shows her as an abusive mother. She's trapped in the time loop, but seems to be gradually changing things. Perhaps when she has righted all her wrongs she can be free?
jess said the whole process restarts when all them dies, just like the other jess who was wearing those black gowns told her that jess must kill her(jess) but she fell of the ship and ended at the beach where she walked back to her home(begining of the movie). there was a black cloth in the water at the beach, the same she was wearing when she fell of the ship. but because many jess`s have died she goes back again where she will become another jess but must first kill the abusive jess who was invited to the trip the day before by greg
