+3, the dingy is an registered/titled boat, just like it's big brother boat. Whatever my motivations for leaving my dingy behind, sailing naked, enjoying a healthy 20+ kts wind, sailing with my runner s to the water. Pay for the mooring, and you are not being a rude person. that said, FMP would be slightly in bad form, but totally defensible.

Now, if someone reserved a mooring that they had not paid for...bad form.

if someone were to encroach, damage, untether a dingy at a mooring...then it becomes a matter of maritime law and should have a nice view from the hilltop with the place with little windows.

Also, the reserved ball at leverick, could be where an awesomely nice person on this board has an longstanding arrangement.
