Just a passing thought.....
Since the oil price crash lots of offshore support vessels and crews have been laid up. Why not contract these people to carry out coastal work?
Put an RN or two aboard the manage the job, and co-ordinate as needed. We have hundreds of trained merchant sailors looking for work, with years of experience going to waste. Why not spend some of that overseas 'aid' budget on looking after our own waters for a change?
Over to you!
