Just to clairify terms. In Australia
where this thread was started Backpackers has a different definition than it does in the USA. Backpackers is a youth hostel. So the question would be translated "To take a crew member
from a youth hostel.
On that note I took some freinds sailing down the coast from Port Townsend WA to Astoria OR. We got socked by 30 knot
winds for a couple of hours as dark descended on us.
One of the crew got seasick so he couldn't stand. IMO Everything will be fine if you don't encounter any storms or rough times but the chances of that are a little slim. I wouldn't do the trip unless I had at least one other competent sailor.
