If the BSS really were interested in 3rd party safety and the reduction of fires and explosions, there would be a requirement in the BSS for petrol engined boats to be fitted with bilge-blowers. (I can find no such requirement, but, I could have missed it)
Then accidents like the boat-fire at Burton waters, where, after re-fueling (with petrol) the engine was restarted and the vapours spilt during fueling went bang.
Several other boats, and the fuel berth, were damaged.
I had petrol engined boats and it was always a pre-starting rule that the bilge blowers were to be run for 5 minutes before starting the engines.
Even my diesel engined boats have bilge blowers - helps to keep the temperatures down if nothing else.
