I've had my trailer base stolen from Thames sailing Club car park.  It is clearly marked 3381 and has a distinctive black painted section at the front.
So, if anyone offer you a trailer base c1986 please let me know

Sorry to hear that Nick. Keep an eye on Ebay!

This seems to be an increasing problem, I know Ben had his pinched last year too. I have a hitch lock I leave on mine when it is left without a boat on it.

Worse bit is when bits are taken off it and not the whole trailer. This happened to me the night before off to the Merlin Championships. I was pleased........

I've been speaking to Mervyn about the combi he has for sale

It also had a hitch lock

All the Soverign Trailers have a barrel in the side of the hitch which prevents the hitch being attached to the car. Very simple but effective. The only concern I have is that you don't actually know it is locked as there is no visual sign of it. In other words nothing to put the theives off trying.

My tale of woe is having a complete 10" wheel and hub assembly removed from a West Mersea road base - a hub cost in the region of £80 to replace, plus nearly £50 for a wheel.  Most wheel clamps wouldn't have prevented it, nor would a tow hitch. Sadly the remote place it was taken from suggested the culprits were probably members of the same club,  but I digress.....

I don't know, obviously, but I think the theives put mine on the back of a truck.Good to have a hitch lock for sure, but it didn't help me. Nor did a set of metal gates with a padlock and chain. What do they want them for?that's what intrigues me...

Checked last night, and ours is still there (but for how long?)

I wonder if they are being nicked for scrap? If they are, its a 'game-changer' as everyone has historically assumed they would be hard to resell & therefore not a prime target...

Don't know if this is any use to anyone? Seems a bargin but it is a long way away.
