Inflatables + outboards are what people want to steal, probably in reverse order. People steal all kinds of stuff, but a dinghy like that isn't going to blend in exactly. My $0.02 anyway.
The bigger problem I'd have is that dinghies generally get abused. They go up on beaches, they haul
gear and jerry cans, they end up covered in sand and dirt, etc. On my walker bay I haul it up by the nose on the main
halyard, then dump buckets of sea
water into it and scrub the floors with a brush before I put it back on the
boat. It's always filthy in the bottom because it's the fun-mobile at
anchor.
Like a dirt bike, golf cart, and minivan all rolled into one.
