I have completed the freighter hijack mission and got Go-T0 as my new team mate. Hte problem is that the Hut and Dockmaster still seem to thing the hijacks are going on and I cant complete that mission from my journal.

 

Still as a DS this time round I'll survive but it is annoying. Any ideas ?

I had that trouble....Even though I completed "GOTO's Yacht", The Hutt & Dock Master kept talking about the freighter hijackings. Finally I just kept reinitiating a conversation with the Hutt & he finally recognized that I completed the quest. It was frustrating, but it worked.
