Flask for quick drinks. Gas stove, kettle and a couple of gals of water. The, now very common, stoves which take cartridges and are low in profile, (good stability) are excellent. They use an inbuit piezo igniter so no matches necessary, have a large burner so quick and they come in a foldable case for easy storage. I've had mine for about 4 years and it's still fine. It's had a dunking or two, too.
Argos, about £20, and lots of other places.
There's nothing like fresh tea with your fish supper. Mmmm.
Can't be bothered with restaurants and bars. I'm out on me boat, why would I want to sit inside in the smoke?
Take a wee basin, soap and towel with you. A nice wee freshen up after eating and away you go.
