To pick up on Edward's point, the sea crossing is very short. I live near one of the wee harbours he refers to, and I know local people who jetski across to Scotland. A local guy has a RIB boat and he can get from Ballywalter harbour in Ulster to Portpatrick harbour in Scotland in 25 minutes! (lots of fuel and horse power!) If you have a look at this link you can see a photo I took up near Torr Head in County Antrim this summer. The Mull of Kintyre is amazingly close. http://www.lowcountryboys.com/hismap6.html Regards, Mark
