Ron, I saw this in your other post. Very cool!
Not to toot my own horn to much, but it really works awesome for my purposes.. Seriously with a little adjustment my wheels just clear the 6x6 blocks in the front, so it just rolls right on and off... It is a dream for me, because the only gel coat damage I ever did to a boat was taking it on and off the trailer. This all but eliminates that problem
If you had cradles you could even build a ramp to go over the front blocks so it was literally in and out without doing anything.. The issue I ran into with my wheels is pushing them up the ramp the wheels would move towards the front of the boat and then try and roll towards the back once over the hump.. You had to tighten them down pretty good to make it look like you were a pro doing it..
So I went with plan "b", and it works great.
My boat is stored inside a gate on that hard packed almost asphalt so crashing it on the ground isn't an option. Even if I could I dunno if I would leave my boat living in the sand just because wind storms ect wiggling the boat around, and it would stay wet much longer (not like I ever let my dry out anyway
I will say though.. Simply crashing the boat on old tires worked very well...
