Don't get a tow
In my sailing classes a long time ago at the Jib set in Vancouver (now defunct) I was given these instructions when going aground.Once aground, usually due to tidal influences, wait until the tide went out further. Grab a pail and some brushes and clean the bottom of the boat to make it look like you intentionally planned your little mistake. This way you save face while waiting for the tide to return.Also don't get a tow, the boat would have been better left where it was and wait for the tide to come in. People purposely tie up to jetties where their boat will be grounded on seasonally low tides for the very purpose of cleaning the boat without having to pay for a lift. Towing the boat over ground is likely to do more damage than waiting out a grounding.Also, what you really want to check is your rudder and where it is attached to make sure that hasn't loosened up. I have a story I won't bore you with related to this very issue, but I will say this: imagine you are sailing and your boat starts to fill with water, even though you have hit nothing, then imagine turning on your electric bilge only to not have it work, then imagine using your hand pump built into the boat, only to have the handle break off; imagine it is getting darker and darker.....
