For anyone who can't afford a Trailex trailer or for whatever reason opts for the cheap alternative from Harbor Freight. I replaced the tires and rim that came with the trailer with two from West Marine. I also added two brackets and changed the bunks to 6 foot 2x4's covered with bunk carpet from West Marine. I just completed a 1400 (approximate) mile trip towing my Skerry on this trailer from Fort Myers, Florida to St. Joseph, Michigan. I kept my speed at between 65 and 70 mph and had absolutely no problems at all. One thing that worried me was the lightness of the trailer and load so I bought a large roll of bubble wrap and some packing tape. I wrapped my cutout but unfinished rudder and daggerboard parts. I have two 14 foot cypress boards I'm going to use for my mast which I wrapped and laid across the three seats.  I had a bunch of other things, Dremmel tool box and everything was wrapped in bubble wrap. All in all I probably put maybe a hundred pounds in the boat.  I bought a roll of that thick plastic drop cloth , not the blue tarp kind, the semi clear kind, draped it over the boat and cut it just below the top plank around the hull. I fastened this with clear packing tape and a 1/8" line under the rail pulled tight. Then I bought a roll of that stretchy packing wrap (the kind like thick Saran Wrap) and went around, over, under and all over the boat. I finished this off with a closely spaced "X" pattern all over the boat with the ends of each piece of tape secured to the second plank down. I also have a bronze bow eye on the boat secured to the trailer and straps across the whole thing fore and aft. Ran into a terrible storm just South of Atlanta on Tuesday evening but everything made it safe and dry.
