Hello Dave,
I don't know if you have tried to contact us but I found your posting here through Google.
If you keep your RIB/boat on a trailer it's "ready to go" for the thieves unless you can "effectively" immobilise the trailer.
Wheel clamps and hitch locks are recomended by insurance, police and retail outlets because that is what is presently available.
We fitted these to our caravan which was stolen, then we became aware that wheel clamps and hitchlocks are easily removed by angle grinders, forced off by stilsons, and even the very best can be removed in 20 seconds using small portable oxyacetylene cutting gear. Chains, ground anchors, security posts, padlocks, steel security gates and fencing are also easily removed.
We realised that our new caravan was vulnerable since the thieves usually return in a couple of months knowing we will have a new replacement caravan "ready to go".
To resist an oxyacetylene attack was the big problem which no other device has so far managed to overcome, and this was the key.
Wheel clamps cannot be made secure.
Removing the wheels will immobilise the trailer but thieves do case the job and will bring a set of stolen wheels.
Locking bolts can be be removed easily using removal sockets.
Our answer is to bolt the JSB HUBLOCK directly to the brake hub using high security locking bolts. The holes in the disc are close tolerance around the bolts preventing use of sockets, bolt heads are anti drill.
The security bolts are now protected and can only be removed using the special key provided.
The disc can't be removed by oxyacetylene and tests have proved it's effectiveness (DVD available). A prolonged attack of 30 to 60 minutes would be required and would destroy the wheel bearings.
We have tested using a Stihl saw which took over 3 hours to remove the disc.
Many people have claimed they could remove the device in ten minutes or less, some very good engineers and mechanics, but all who have taken trouble to see the device have been convinced.
A thief can complete most jobs in less than ten minutes so the JSB HUBLOCK will be avoided, as we know from experience with three white vans and six burly thieves recently defeated. (posting Practical Caravan, forum, security and insurance, "the gypsies are back".)
The majority of our customers have had caravans stolen and understand the extent of the problem with 4,000 to 5,000 caravans stolen each year.
Many have had caravans stolen twice and a few three times, after spending a lot of money on wheel clamps, hitch locks, security posts, gates and fences.
This posting has been made to inform you of our experiences with caravans, similar to problems you have with RIB/Boat trailers.
