OK... ferry... a compact package is just as good to have as for flying or train travel.
Of course, it all depends on what range of gear you have in your panniers and handlebar bag. I can say that I didn't want for anything on those trips or others, and that included a full Trangia cookset, a three-person tent in 2007, various changes of clothes and warm and waterproof gear. Oh, and a pair of flip-flops for showers and off-bike wear.
We usually didn't carry much in the way of food, although enough to get us out of a bind on one night. But we left the food and drink buying each night to the last town and stocked up with only a few miles to ride.
A note, however. Where we rode, across the north and into the east, dots on maps often indicated just villages, and they are residential locations. Don't rely on there being shops available at every dot on the map, because they aren't.
