Those moorings in Housatonic are taxable to the town like property tax and you have to pay monthly dues for upkeep. I looked into those as well but for me the deciding factor was the 15mins of motoring just to get to the sound.
I use the Milford town floating docks in the Milford Harbor. Good for May - November for about $25 a foot. For storage most folks store up in Housatonic river for $35 a foot. This scenario is probably the cheapest you will find in my neck of the woods.
"estopa" - [est'opa] is portuguese for Oakum.
