Underwater directions: Diving the B200, enter the water on the right of the wooden pier and go straight down the 45deg boulder slope to the bottom and turn right, the wreck is 5 meters away at 43 meters. Diving the bay, enter the water on the right of the wooden pier ( facing the bay ) and go down the 45deg boulder slope to 15meters and turn left and exit on the other side of the bay (long walk back to car) or if you have plenty of gas come back to the entry point. The wall is supposed to be off the point on the far side but can't confirm that yet.

Dive reports: John May 07   Started at the side of the pier and went down to the B200 and headed out to the drop-off but turned back at about 55m and came back passed the B200 and went around the bay at about 35m. The big boulders here are good for a look under as big fish and congers like to sleep through the day here. Bye, the time I got to the faraway point near the fish farm I was in about 25m. I fined back to the pier in less than 10m for a good long decompression. Max depth 55m dive time 135 Min's Dil was 21%

Dive reports: Stew, May 07,   dived at furnace today with Davie G. the viz (2-4m) was appalling, the water was thick with green particle down to around 20m. below that it was much better, we did the B200 & had around 6m viz on the wreck. I noticed for the first time that the wheelhouse has been ripped apart. there is only one side left & a small section of roof with the window glass still in place. have I been narked all this time & never noticed this before or has someone had their crowbar out? pretty sure I have seen all 4 sides on it with the doorway, last time I dived it!
