I have spent the last day or two adapting my already multi purpose trailer to be able to transport and store our SIB. It was a fairly simple and quite enjoyable job. We had sold our speedboat and the large trailer it sat on and didn't want to have the clutter of another trailer lying about so this seemed like a good idea.
These are the mods I made to take the SIB (there are still some bolts to cut down and the extension bar needs painting but you get the picture)
This is the 2 x motorbike mode
And this is the Tip, DIY, camping mode
The bunks, transom support and drawbar extension are easily removed to return it to a utility/bike trailer.
This gives us loads of options ref transporting the SIB. We can roll it up and put it in the trailer with the motor, freeing up space in the car. We can put the motor in the trailer and boat on top or we can put the boat and motor on the trailer and use the space in the original trailer for luggage etc. Finally we don't need to use the trailer at all depending on who is going on the day out. It will never go in the water just being used for transport and storage. It also means that if we go away for a few days the boat can be left inflated to save time.
Now I just need to get on the water!
