The trip was successful and I will write an update (honest) i just need to find some time to do it...
Simple update was : varired weather (well it was the UK in april), good times, some hard work, maxi adventure/exped had.
Worth it - yes!
Even in this little post, I've gotta thank friends mark/amanda who lent the boat. It was a big ask but we looked after it and it performed brilliantly.
