There are guys who make a living installing these things. They have the
equipment and knowledge to get it down right.

And they will know if your installing in a designated or proper mooring
location.

You'll want to verify wheather you need a permit to put a mooring down,
before you spend more than a few hundred buck on this mooring.

A fellow just dropped an old 30# anchor and mooring bouy (beer keg) just off
my marina slip. It fouls the approach to a ~ dozen slips. I'd call it a
hazard to navigation, but we have no USCG or other agency to contact in this
area. (I'm just hoping a good winter gale will take care of it this winter.)
