Stupidity: When they are in Italy on the boat, they find out they need to go to Montecarlo in order to reach Switzerland. They have a chopper. Italy is right next to Switzerland. It makes no sense that they would take a boat to Montecarlo to get to Switzerland, especially given the weather they'd have to sail through.
Stupidity: Darren could have easily grabbed Ben out of the locker he climbed into by just pulling. Instead, he pushes it inward, causing it to close and allowing Ben to either hold onto it on the inside or lock the locker itself.
Suggested correction: We don't know where in Italy they are. If they are all the way in the south, there is no way a helicopter could make it to Switzerland on a single tank. Then he would also have to consider clearance for airspace, where and how to refuel etc. In short, sailing to Monaco and flying to Switzerland from there is much easier.

Clearance to dock in Monaco is needed if you sail with a large ship. Same trouble than air clearance. Using a helicopter is still faster, even with the eventual refuelling. Switzerland via Monaco makes no sense. They would still need to use the helicopter or a car from Monaco on.
