This involved three newly-married couples competing.  The second round was called "The Sea of Matrimony", though it was actually set in a leisure centre swimming pool.  The couples were in boats, each boat had holes in the sides to let water in.  Questions were put to the couples in turn, and if they got an answer wrong, a member of their family had also to get into the boat, which made it heavier and therefore more prone to sink.  The first team to sink or capsize their boat was out, the two remaining couples went through to the next round.  

To make things interesting, the couples were dressed in their wedding attire, and the members of the family were all fully dressed in expensive clothes.  I recall some nice shots as sisters of the bride or groom descended into the water and had (presumably) had their outfits ruined.
