I really enjoyed this film, it was surprisingly very good! As someone who has been bought up on yachts, I can appreciate how challenging it was to film those scenes. Also, even though I knew this was a horror film, a lot of it could be explained rationally but some of it had a supernatural feel to it. Also, I loved how they never actually showed what was causing the creepy things to happen. I think it made it creepier. As someone who knows a lot about yachts, I could see the main actor (the only actor) definitely knew how to sail. I give it 5 stars.
