An engine with a theft deterrent cover cannot be sold
A scheme to protect maritime equipment from thieves in Devon has been hailed a success by police.
It includes security packs, micro dot marking equipment and an "immobilise" database for boat owners.
The security pack includes a theft deterrent cover for engines, which is marked with the Devon and Cornwall Police logo.
A police spokesman said the scheme had attracted the interest of a large insurance firm.
Crime reduction manager Sgt John Livingstone said the aim of the scheme was to keep maritime equipment "out of the hands of prying thieves".
"Theft of small and medium size boat engines increase during the summer months," he said.
"Often, boat owners are not aware of simple and cost effective security measures they can take to avoid weeks of inconvenience and costly replacement of engines caused by marine thieves targeting local harbours."
When a boat is moored, removing the manufacturers' engine cover and replacing it with the "theft deterrent" cover makes its engine non-saleable, while the microdot marking solution has a unique reference number, which allows marked equipment to be identified with the use of ultra-violet light.
