Obiously it would depend on where in Scotland you were travelling to, what form of transport you were using, what route you took and what speed you travelled at.

From where?
Glastonbury is in Somerset, England. It is not in Scotland.
Assuming a small dinghy like Finn Class can develop speed up to 5 knots (let's say 10kph) and a rough distance form Norway shore to Scotland shore is about 500km, I'd say about 50 hours, so maybe 2 days?
That depends on where you are travelling from.
3 hours
depends on where your coming from...
You can be in Scotland from Dublin by air in less than 40 minutes.
Scotland is a big place but from Edinburgh, 8-9 hours.
