This happened a few weeks ago when my internet connection was down. It wasnt at my local club as i was visiting relatives but apparently the local scuba club worth happy to salvage it. They salvaged it by placing inflatable belts under hull then inflating them. After it was salvaged they weighed it with water in the areas that had been flooded and it was said to weigh between 35-45kgs, that massive compared to a fully ballasted 12kg when first put in the water.
