We were stopped on the way to Burnham on Saturday . Because there was a public weighbridge close by , I was expecting a thorough trailer check , but it turns out that Essex Police were promoting their Marine Watch Scheme . Apparantly threre has been " a high number of boat related thefts " , they were spot checking anything water-borne on the road . The chap with the jet-ski in front of me didn't look too happy as they were showing quite a bit of interest in his PWC . Anyway if you are Essex based , or regularly travel through there , you may wish to register all your boat's details on the police website . Sounds like a good idea to me !
