Our comfortable yacht is available for your luxurious stay on the San Joaquin Delta! Stay overnight on your way to Yosemite or Tahoe. Bring a ski boat, wakeboard/ski & discover the Delta & its waterfront restaurants then relax in luxury on your yacht. Island Oasis DOES NOT leave the berth, but to enjoy overnight. Boating is a seasonal adventure and pricing does reflect this. For me, summer is the best when you can enjoy the SUPs, Kayak and Paddleboat, others prefer the wildlife in winter.
