Hi Keith, I think it has been 5-8 years? I really don't know. It was tied up to the pilings near shore and sank under "mysterious" circumstances. It actually settled against another boat, a wooden fishing seiner that is deteriorating fast. There isn't a lot of growth in that area regardless. Britannia Beach is at the terminus of the Howe Sound and there is very little flushing there to bring nutrients. The site was also very polluted by tailings from the mine for many years and is a bit of a success story as far as contaminant cleanup is concerned. Britannia Beach was famous in the early part of the last century when most of the town was swept away by a torrent of water from a debris dam giving way above in the mountains. Just google Britannia beach natural disaster.
Also, just north of this site is a dive called the Britannia Wall. This is a large wooden structure that was originally an old barge filled with rock and used as part of a breakwater/land reclamation project. BC's first recorded submerged landslide took place there and swept part of the barge away, leaving the remaining hull standing like a big wooden wall. Now life inhabits its many crevices.
