Name: Benjamin Lim.
Bed: Bottom of bunk-bed at front of boat. Place #4 on diagram.
I've known Ben for almost as long as I've known Mark and Finbar. He's always been the sensible, level-headed member of our group. In fact, it was Ben that carefully drew up our itinerary for the week, and he did a good enough job of it that we only briefly couldn't keep to the schedule.
The fact that Mark and Finbar were planning the trip was probably enough to persuade Ben to join in. And he was probably looking forward to a break after all the studying, some freedom and independence, because at the time of planning we were all just about to start A-Level exams, and Ben was definitely working hard to succeed.
Ben, too, was probably looking forward to the many pub stops, but I doubt he was hoping for an orgy of drinking. Ben is not a person who tries to get mad drunk. If anything, a few units of alcohol seem to make him more solemn.
