The seasonal mooring fee is $100 in my harbor, for residents ($250 for non-residents). Dinghy space is available at an extra charge.
It costs $1 to launch a skiff -or 80 footer - at the public ramp; honor system cash slot.
The docks on the right side in photo (there are 200' additional today) are publicly owned and free to use for a couple hours (locals use them spring and fall longer, overnight, for free).
We own our mooring tackle and have to inspect it annually.
Our boat spends the off season on the public landing along the river (lower right in photo). This storage has gone up significantly the last decade to $800. Still a good deal for 38' boat in the area.
We're lucky today; more than a century of smokey industry (Lime production-ice houses) and fishing kept our town/harbor in a preserved state of poverty until a half century ago. By the time our harbor front became valuable, the had town realized that value, and wouldn't sell.
We're still a working harbor with most of the shorefront publicly owned. It's changing quite a bit around me these days, but our public access (and reasonable cost) to the water is secure for the future.
