Fair, but being boatless is an empty feeling. Your freedom to seek solitude on the pond could be lost forever!
It's best to keep a smaller multipurpose sled around just incase a situation like this pops up

This is the thinking my wife rolls her eyes at regularly.... but it's defensible!
Recent example: some dude sees my little 15' whaler and offers me twice what I have into it including every gallon of fuel through it from the last 5 years. NOW, if I only had the whaler I'd tell that guy to pound sand and get his greesy eyeballs of my boat. The thought of selling would be outrageous! Because I have the big boat I don't have to stress about the potential for being boatless for more than a couple weeks and can make the financially prudent decision to let go the whaler and take profits. See, perfectly sound logic
