We planned the same route except in reverse direction before we gave up on Fiji
. That was 2004. I had the whole thing already pre-planned (or so I wrongly believed - read on) back then - also this particular passage.
I remember our charts
were pretty good (we carried some BHO and some FMD charts) and the pilots (Sailing Directions) seemed informative too. We had one cruising guide (can't recall
the name though). I did not find the area poorly charted and I believed with the charts and the pilot I could sail from Yadua to Yasawa over the deep water
channel of Bligh Water! I might have been an idiot.
I am puzzled as to the 'inside reef along Viti coast' route. I believed the Bligh Water passage was THE route - looked all deep water to me.
I will standby and listen to what others say as I may have had a completely wrong impression of Bligh Water from our charts.
BTW Which charts of the area do you carry?
