150-200 mph (kts?) cruise is faster than anything I've flown. Only 30 mile trips from base in such an aircraft is surprising.
I've flown over Scottish sea quite often. Over the mainland, I'd often consider ditching in a loch, colder than sea water, if I had an engine failure. I always wear a lifejacket.
You'll have good radar and radio cover.
At 10,000' you're likely to be above cloud, and with icing on descent through it.
