Heck that's a really good question!
No simple answer, but I'll have a go. A few thoughts:
- Firstly leave word with someone about where you're heading and when you expect to return, so that someone can come looking for you if you do get into trouble.
- Go with someone more experienced a few times if you can, and learn from them.
- Talk to fellow travellers and always be picking up tips and ideas. You're never to old to learn.
- Pack your boat at home first before you go, to see what you can fit. Jettison the things you don't really need, but don't ditch all the luxuries, you need some comfort out there!
- Take clothing that is warm but which dries easily. Then you won't need so many spares. You don't need to change that often in the wilderness, there's no one to smell you and you can always take a dip in the lake/river.
- Take a spare paddle. Or two.
- Take a good sleeping bag and make sure it stays dry in a good water tight dry bag.
- Don't push yourself too hard on the trip. You'll learn how much your comfortable with doing as you gain experience. Don't be afraid to pitch camp early, if you find a nice spot and if conditions are good.
- Don't be afraid to turn back, if weather/wave conditions deteriorate, or find somewhere safe to wait it out
- Take a cellphone to contact the outside world if needed.
- Don't forget the flashlight. And batteries.
- A drop of whisky (or your favourite poison) never goes amiss. :)
Probably loads more, but just a few ideas for starters...
