Chris Hiscock had a local aluminum trailer built for his F-33, and this is one of the best I have seen.
It can be tricky to get a good trailer, and it is very important to check that it has been made to plan upon delivery.
The plans supplied give all the details needed, but be sure to check lengths and heights, and that all supports are
present as shown. In the past, Keel planks have been 80mm (3") higher than that specified, while bow supports have
been omitted altogther, one case even having unprotected bolt ends sticking up right where a support was supposed
to be. You can guess what will happen, and you would be right. So just be careful, and don't pay trailer manufacturer
until you have checked and measured trailer
