You mean these? http://www.tiedown.com/aglideons.html I do not see why not, but I watched a boat FALL off a trailer at the ramp since it was not tied down still as it was getting backed down the ramp

I recommend you just drop the trailer into the water a little further, and then use the outboard to pull her off the trailer... Shocks me how many people try and fight with loading and unloading a boat yet have a engine just setting there propped up and turned off? Drive it off and on the trailer and learn how to use the speed knob on the helm wheel just remember to go slow

I also highly recommend though (if not already mounted) you get some of the taller PVC pipe covered guide ons so that unloading and more important "loading" the boat back on in a high cross winds is much easier
