Beach launch trailer upgrade

Last year I purchased a small beach launch trailer to take with me on my caravan / sib excursions.
Idea was to carry the Honwave T3.8 sib deflated along with Tohatsu 20hp outboard in the back of the car with the back seats down.
I intend to spread the remainder of the load between car roof box, car boot and caravan.
There are a few sites that I frequent that have beach / slipways to launch the sib on the hence the Sib lives on the beach trailer during my stay. I added an old trailer hitch to tow it on the car around the site.
Although handy this set up has kinda tied me to using certain camp sites that gave boat launch facilities.

I thought.......what if I modified the beach trailer to tow the T3.8 on the road?
I have one camp site in mind, it is one of my favourites, however the site is around 3 miles from my preferred beach launching point.
I dont intend going above 30 - 40 mph.
The road is very quiet / rural.
With upgrading in mind I set about ordering some indespension units mud guards and 8 inch wheels with tyres.*

The road axle halves in the middle for ease of storage and for transporting.
I intend taking the road axle and an old trailer light board when launching the sib off site. If I'm gonna launch the sib on a particular site I will leave the road axle in the shed and just take the little plastic beach wheels instead.

The Sib will only be towed with the outboard off, and stowed securely in the boot of my car. Once at launch point the sib will be taken off the trailer and wheeled on its launch wheels next to the car boot where engine will be lifted out and onto the transom ready for immediate launch

Very neat solution to suit your needs Kaman. I would have no hesitation using that on the road in the way you describe.

Funnily enough on our hols soon we may have the need to move the SIB just a couple of miles from our base and I started a thread a few months back about car topping the Aerotec inflated.

It seemed to be a good idea but after testing the theory a couple more times it became clear my crew (wife and small 19yr old daughter) were struggling to lift to that awkward head height needed so we've given up that idea.

Your solution would be so much easier.

Bought the wheels, mud guards and indespension units on Fleabay.
Axle was free - perks of the job.

I think that's a great solution for a hard boat but you need deep pockets. It's about 1000!

Howdy Fenlander.
Had been mulling over the concept of welding up the road axle for a while. A recent 5 day caravan / fishing excursion with my old man persuaded me it was a worthwhile venture as it was a real chore inflating deflating / wrestling the T3.8 in and out of the car - not to mention the sand everywhere. The beauty of the trailer is once it's built (12mins) the Sib can sit on it until the end of the excursion.
Hopefully the weather gods will be favourable this year.
