Many years ago (around 40 ish) an offshore model power boat (before the days of OMRA I might add) racing in Portsmouth harbour lost its way( well radio malfunction---early radio what did you expect) and hit a full size cabin cruiser, result:one large hole in boat, not much model left,closely followed by much abandoning of cruiser as it began to take on water (rapididly).
Epilogue: First (and possibly only) time a full size boat has been sunk by a model, MPBA insurance company shells out for salvage.
It is not known what happened to the remains of the model (or indeed the modeller) unless of course someone out there in Mayhem land knows............ :-\
