I remember seeing this movie when I was younger. It was about this family getting lost at sea and I think it was in the bermuda triangle, they get to this island I know that the daughter had a crystal necklace that this guy on the island all I remember about him was he wore some kind of red leather and thought the girl was special because of her necklace and kidnapped her and took her to his castle(?). I'm not sure if I saw it on abc family or not. I think that I seen it in the 90's.

I found out from my dad that it was a scifi movie but he can't remember the title either and that it was a 90's movie.

I found it. If anyone wants to know what it is its Escape from Atlantis (1998) (TV). Wow I feel so much better.
