Richard,
Glad to be of help.
At the time of the trip, one guy was 80 years old and the other was 56. Ted, the 80-year-old, instigated the trip to raise money for ALS research, because his wife had recently died of the disease.
Unfortunately, this may not be of help to the person who really wants to know how to store camping supplies for a week on a Hobie 16. I am still looking forward to a realistic answer to that question.
If it were me, I would use the internet to research backpacking -- if hikers can carry everything in the pack on their back to survive for a week hiking in the wilderness, I figure it is actually easier if you take that big backpack and tie it to the deck of your boat just aft of the mast and let the boat carry it.
The key is to condense, consolidate, and center the weight, whether it is on your back or on your boat.
