No Argie howitzers used anywhere to the best of my knowledge
There you go, easy peazy. Made from materials readily available in any warzone.

I really like the nose snubber on this trailer. Custom to suit the bow.
Great idea.

Obviously it would be necessary to modify it to make it UK road legal (you might want suspension, brakes and lights for starters!) but the basic design of the trailer can be seen in the pictures.

Not at all in the same league as Bedajim's trailer, but what it provides is a very strong trailer (it has been used off road by other owners and will be by the new owner) which supports the boat very well off road and on rough roads - it has full length keel support and the bunks lay flat against the hull so it's about as good as you could get in that respect. It means it needs a steep beach to launch on, but there is such a beach exactly where I launch anyway so it wasn't a major problem once I got used to it. Smaller wheels would have reduced the depth needed - it had 7.50x16 Land Rover tyres fitted. It also had an extending drawbar - the hitch was mounted on snug fitting box section slid up inside the main spine of the trailer and retained with 2 x bolts through horizontal holes. Take those out, and you could pull the drawbar out about 6ft to get the boat further into the water, though I never used it.

It is based on old Land Rover hubs and stub axles welded onto the axle tubes so the wheel bearings are cheap and easy to get and pretty heavy duty as well.

Damage proof mudguards another great idea.

Finally there are plenty of good second hand tyres about as they are changed after 50,000km on most cars due to effects of the sun. The double axles are built onto a bogey that can be moved fore and aft to get the nose weight of the trailer right for the tow vehicle. Once positioned it is locked in place with U bolts. The trailer has central rollers and bunks and can use a normal trailer boar for lights etc (however there are no rules here regarding trailer lighting). Best of luck with your plan; I know that you will get plenty of support and advice from the site users.
The double rail.
looks very nice.great job.

I just splashed the nose snubber off the rib while it was upside down and lined it with carpet.The FRP is about 6mm thick and about 9mm around the hole for the winch hook.
The poly skids on the trailer are very low friction. If I was to release the rib at the top of the ramp it would slide off onto the ramp.

What size did you make.
I thought about it, but by the time I had bought all the running gear, fasteners, rollers etc and got it galvanised, it was going to be about another 50 for someone to build it for me!

Needless to say I put the order in for a new trailer!

Many thanks for the information I will be using this idea.
safer and better than a small rubber snubber.

My trailer cost about AU $3000 total to make,It would have cost about AU$ 6-7000 to buy from a manufacturer.Not a bad saving. I did have a mig welder and metal cutoff saw already.
