The trawlers name is "Niamh Cinn Oir", which in English translates to "Niamh of the Golden Hair". This name relates to an ancient Irish story which it could be said may relate in parts to the film.
The early scene where the captain discusses paying shares with the two crew members who work below deck is a reference to the similar conversation in Alien between Dallas, Parker and Brett. This film shares many similarities with Alien despite the difference in setting.
The 2nd trawler they come across is Spanish. Her name is Santa Maria (Saint Mary) , all the signs are in Spanish and below deck in the dinning area you can see a large Spanish flag behind the sailors.
