I'm planning to sail roughly 90 miles from White Rocks Marina MD, down to Smith Island MD. But I'll be picking my wife up in Crisfield MD, and sailing over to Ewell on Smith Island along the ferry route. My question is: the channel for the Ewell to Crisfield ferry looks pretty sketchy. Do any of you have first-hand knowledge about this? Our boat draws 3'10". I've asked the same question on our slip-holder's website. Thanks!
