As far as i know, there are a couple of up island operators that will pick you up at your dock. The only one i know is White Sands, so why not email Elbert at WS and ask him? Also, another shop in town i recommend is Chuck and Robbie's. Even though they are in town, I once heard that they'll pick up, up island. That may no longer be the case. Again, recommend you email the question.
