We must have spoken on my trips to Dundee.
I also do both but fly much more these days.
I also agree - the advantage with flying is you can always find time for a flight and all in all the time to ready the craft and pack it up is usually significantly less. Inevitably if you derive pleasure from going places flying makes a great deal more sense.
Sailing across the English Channel for me almost always takes at least a day and sometimes a little longer. In practical terms a trip almost any where is a weekend affair. On the other hand it is 30 minutes at 170 knots in the aircraft.
If you are inclined to be lazy (like me) access to the aircraft / boat is important. If you must move three other aircraft to "get" at yours and it takes 45 minutes I bet after not very long you will find excuses for not flying.
I will go back to sailing when I do a round the world cruise in an IP with 50 feet on the waterline but sadly that may be a few years away. That is something you can only do in a yacht unless you are in a very different aviation league from me.
