We haven't been through either Kent or Knapp's Narrows for a few months, but we have boatloads of buds going through both of those all the time... shouldn't be a problem, just follow the markers.
Since you're going to Oxford, you can also go to Cambridge; worth a visit. The Hyatt offers a bit of a deal (3 nights for 2) at serious expense
or the city marina is within walking distance of the downtown area.
And since you're going through Kent Narrows, a side trip to St. Michael's would also be worth some time. The main way to do that would be down the Miles River. Easy access to the town, three marinas to chose from (Higgins Yacht Yard is the least expensive), veery decent maritime museum right there... Or another way would be to hang a left en route Oxford and anchor out in San Domingo Creek, sort of on the back side of St. Michael's, and dingy in to the public dock back there.
Wave if you see us en route Florida later on...
