Here's my suggestion ...... instead of increasing the size of the public town docks around the lake ...... is better to limit the size of the boat allowed on the lake!
My proposal; limit boat use to a 14' aluminum, vee hull, open boat with a 15-hp tiller handle outboard.
Besides using the outboard, it can also get rowed by two rowers with four oar locks and four oars.
Say hey ...... is there a need for bigger docks ...... probably not if everyone can only have this 14' boat! .....
