    I don't have a FZS but I know alot of people measure the space between the bunks on your trailer and use that distance and about maybe an inch lower. Thats how I made mine and it works excellent! I learned though that you should see how hard it is to reach inside your hull to work with it on the trailer and then determine height from that...my next one I make, I will prolly make it just a bit lower because it might be nice and easy to get it off the trailer, but I still feel it in my legs sometimes when I have to stretch for some spots. Just something to keep in mind!

    Thanks buddy, that s good info to get started
    so the lower the better, and at least 1 inch lower than trailer

    Would an inclined stand be a good idea?
    it was thinking to make the front higher by 5-10 degrees, so the angle matches the trailer inclination when tongue up
    that should make it easier to slide down the ski

    also, are rolls a good idea on stands' bunks? anybody tried it?

    and is there s some way to adapt a trailer winch to the rear of the stand,
    so as to pull the ski backwards?

    any ideas welcome

    Hi Petrus, did you manage to build your FZS stand? I am also going through this now and would also be happy to hear if you had a good experience with it. Thanks!

    Yep, just finished them! it took me a while as i had to learn from scratch, without much advice from the pros as you can see
    But i am quite happy with how it came out

    I went with rollers so i can easily swap my skis back & forth to trailer, just by myself without a power winch

    I made the supports adjustable to 5 positions, and the rails themselves can move to 15o,
    so it can fit both my rxp and my new fzs, or any kind of hull

    I m just done painting the 2nd one in white, it s curing right now,
    i think it looks much better in white

    You like them? let me know if you need any help

    That looks cool! Is it your own design? I also need a stand for an FZS, and the dealer here only has some pretty crappy looking stands. Yours look nice. If you don't mind me asking, would you allow me to copy the design and ask a local workshop to build me one here? Your location says Gulf of Thailand? You're a resident there? I am in Thailand 3 to 4 times a year, in BKK or Phuket. My wife is Thai. Maybe we can meet for a beer one day?!

    Sure mate! go ahead, let me know if you need any more pics or measures
    I designed it and had my friend cut & wield it, it was a fun project
    The rollers/bearings/wheels are not cheap, but now i can get my rxp on/off the trailer by myself without breaking a sweat, just push gently and it will slide,
    always make sure you strap ski to stand at the rear

    I live in Hua Hin on the west coast, 2h drive South of BKK, the gulf is always a bit rough so i usually ride on the Mekong & ChaoPraya rivers, and the Kanchanaburi lake up the Kwai river
    You are welcome anytime, just let me know when you can make it
    Cheers,
    Tony

    Hi Tony, I ordered some materials today for the stand. I'll borrow part of your design, so I do owe you one. Will put it together this weekend. Let's see whether mine will be as good as your design

    here some photos of how the stand came out.
    thanks again for your help with the design idea!

    for reference, the base is 100 cm wide, 150 cm long and the wooden support is 200 cm long.
    caster wheels are good for 200 kg each

    Hi ATO,
    Looks good & strong, but are you not going to wrap the bunks with some carpet fabric? or at least glue a layer of rubber to protect your hull?
    On your pic it looks like the ski is resting directly on the bare wooden support

    You have to be gentle not to dent those fragile CNC hulls, that s whyI went with 2x5 oversized rollers instead of just 2x4, to balance weight and reduce pressure points on the hull.
    I went with galvanized steel because i had some left over from a trailer project, but plain steel is good enough, dont waste $ on aluminium neither.
    Here are pics of its white twin
