The first part of the day was terrific. The trip out to the Estuary on Knight Inlet was all good. Over the course of the morning and early afternoon we saw 9 Grizzlies and various other wildlife. The Lunch was also good. There were 11 patrons in addition to the operator who did an excellent job of guiding us aboard the Keremode. Everything met or exceeded our expectations. Unfortunately, on the way back to home port things began to go from bad to worse. About one hour out while still in Knight Inlet the power steering unit on Keremode broke down causing us to move in circles only. The operator did try to fix the steering problem to no avail as a major hose had ruptured. We began 2 plus hours dead in the water with breaking seas of about a foot or so. An attempt to steady the boat with a sea anchor was soon abandoned as useless due to the small size of the anchor. A series of radio calls back to home base seemed to indicate that no back up plan existed. At no time did the operator make any attempt to secure a commercial tow. He did attempt to contact Prawn Boats in the Inlet but admitted that he did not know what radio channel they operated on. Eventually a second boat arrived from Telegraph Cove and a potentially dangerous transfer of the 11 patons occurred in seas that exceeded 3 feet. At no time were life jackets suggested to passengers. What was supposed to be a 9 hour day turned into 13 plus hours. The main question asked was, why is there no auxiliary power for the boat in such potentially difficult waters. Also on our minds was the question of no obvious emergency backup plan. It was a case of a good experience turning vey sour vey quickly!
