So, hubby removed the boat (it was one of those inflatable ones, similar to what you might see James Bond speeding round the Thames on, but smaller!), and now we are left with a trailer that has a length of 3.2m (longer to the point of the tow socket thingymejig or what ever it is called - 3.2m is the square flat bit we can build on).
We're going to use materials from our collapsed hangar, there is plenty of wood there and some metal sheeting too! Just need to be sure we don't go too heavy, or we're going to need a bigger trailer.
Any ideas are most welcome, even if they're a bit crazy!
