As for paddling the http://www.bcmarinetrails.org/
is attempting to establish a network of camping locations 20kms ish away from each other.
Paddling speeds differ greatly depending on the type of craft, load and obviously your skill level. Then weather plays a huge roll on top of that
As for a sail boat well that is a whole other area...
Most likely costs are WHY higher, size of boat, if your going to trailer it or moor it.
Then obviously a sail boat has way more potential being that it is wind and motor powered.
I would say a sail boat is better and then put a hobby kayak on top. But again a sail boat or any boat is huge money.
