I spoke with the Dockmaster and Harbortown and got a different slip lined up.  Our current slip has only an 11-foot finger making it very difficult to board without backing in, bur backing in means very little privacy for us in our living room, er, cockpit.  So we're going to a slip with a 22-foot finger this weekend.  It will be my first experience at the helm and April's of docking and line-handling.
