I share your views on the issue Chris but, there are more implications than just popping over there to pick a few people up.
There is a mass of documentation to get in place for a trip to France, as well as the huge safety issues to deal with.
Personally I would not be happy taking part in a venture like this as the safety and welfare of those on my RIB is my primary thought at all times and I can't keep people safe if we don't speak the same language and they don't have suitable lifejackets etc.
I think this call by Bob Geldoff was either a spur of the moment thing or something that is at the least foolhardy and at most has the potential to be bloody dangerous.
As previously stated, it would be far safer for those who wished to join in this venture to come over by ferry.
This call to action could encourage people with craft not capable of such a crossing to try it so endangering themselves and those who would have to rescue them.
