Yes there is a ramp at the Narrows directly across from Red Eye's. Stop bt a sporting goods store and pick up a ramp pass(public)
There are also ramps in St. michael's which is also close to Easton-also public.
Red Eye's is cool. St Michael's is nice-check out the Crab Claw. If you go north to Rock Hall, Waterman's crab house is the ticket. Red Eye's has bikini contests on Sunday afternoon
Profiling through "Ego Alley"in Annapolis is cool. If you can tie up at Pusser's and have a few Painkillers it is even cooler
Wind from the north or the south can make things bumpy, Annapolis is always bumpy, and watch the current in the Narrows. A 28 should be fine unless conditions are unusual.
All channels tend to be well marked, another rule of thumb is if you are surrounded by crab pot floats you have enough water. Just don't run over the bastards....
Any other questions let me know. It really is a great place to boat.
