Launching Wheels for Inflatable Boat 10 x 3 Stainless Steel Dinghy Wheels, Kayak Yacht Easy Transom Trolley, Max Load 280 kg, Blue, for Short Distance Beach Moves

Easy enough to fit to a 3.8m SIB. Seems fairly stable. The only thing i would change is to remove the centre pin (hinge) and use a bolt, when to unlock it to put the wheels up it can/has come loose and nearly fall out luckily was on land. You can also put the wheels up at 45 degrees if you have rod holders/ mount of the transom for trolling like i have.

All suppliers at this price have the same product and it is reasonably priced.BUT:The wheels run on the threaded portion of the bolts and will thus wear quickly.The clips have a loop over locking clip that means they cannot be folded all the way up. They have to be removed and them put back on retracted, making dropping something over the side easy.Both faults are readily fixed. Just buy 120mm bolts with a shank and a few washers the drill the pivot clip and use a R clip.Neither option cost much, I fixed mine for less than £5.
