I don't think they have a phone at Schaeffer's these days. The place has been under very slow renovation for the last two years. They tried to pump fuel last season but the docks are still in bad shape and nobody seems to care much about the no wake zone.
Maybe they're trying to pump fuel again this year, but last time I passed by it (about two weeks ago), there was noone there. Summit North seems to be the only relaible fuel option on the C&D. They will also give you 5 cents off for over 100 gal. As an aside, I assume you have empty tanks and don't want to fill up in Georgetown. Otherwise, an average cruiser should have plenty of fuel to get you from Skipjack to Cape May, NJ. Top off in Cape May and you're good to go to Toms River.
