This historic 1930s lightship is in fantastic condition. Below decks requires a guide. It's not an arduous tour, and is very interesting - the guides are knowledgeable and the whole thing takes about 45 minutes top to bottom. The tour covers the pilothouse (the bridge), radio room, and then down across the first level below, stem to stern. Tours do not go to the lowest deck where the engines and generators are. There is also no access to the upper deck where the mast is. So visitors can see the main deck, and the lower level, as well as the interior of the superstructure. I really enjoyed seeing the different seakeeping features of the ship. The surrounding park was also very nice. The lightship folks own the little historic Monomoy surfboat under the pavilion, while Lewes Historical Society operates the Life-Saving Museum - a great companion site to the lightship & surfboat - immediately next door. In my opinion, these are all very related topics (Lifesaving Service and Lighthouse Service) and should be visited together. Check the website for specific hours, as the days open depend on the season. There is ample parking in the gravel parking lot for the Canalfront Park, but I would recommend considering parking on the street up by the Episcopal Church if its a Little League game day (assuming the parking lot fills up quickly on those days).
