I live in Retford Scotland for me every time 7 hour run to Oban area we use to go Friday come back Monday in my 60's we go for a week minimum now but I have a 3.65 m 25 hp on a trailer and push it in on sand at times but there's plenty of slipways around you have to pay but go to a marina put her in for the duration of your stay less hassle
Tom, PM me your plans. I live at North Berwick and may be able to help out. I have a Discovery 4 and can launch you at the beach or one of the other local sites if you come this way - as long as the Disco doesn't break down
