Just in case anybody ever wants to buy a new windsurfing trailer: i recently bought one from
www.tealeservices.co.uk . this was made to measure, full aluminium construction making it very light. it fits a lot of gear. Darren who built it put in some adjustable racks for me. it tows very well and the build quality is great. competitive prive compared with mersea gemini or tst. I found Darren great to deal with and i'm obviously happy to recommend his services! (no, i'm not getting paid for this
