The protected Linden land turns into shore, the only open waterway is in the next sim to the east, and the owner of that land has acccess restricted it. I attempted to sail my Tako through the waterway only to have the combination of access-denial push and sim-transfer leaving me two sims away and at the bottom of the channel. The protected waterway needs to be reopened here.
Also, deepening the waterway would be nice. The group I'm in has bought a parcel of land right against that and it'd be good to have access into it better.
