What's the angle in that ramp?
Dunno. I'd have to take a level and protractor to find out. It seems typical, though, as we launch our Catalina 22 here and at other ramps and have about the same experience. This page shows that the ideal ramp is 12-15% or 7-8.5 degrees.

I'll have to take my level and square out again, but I think this ramp is up in the 15deg+ range. It's much steeper than your standard roof. When I had the jeep I was regularly pulling guys up and out. Now they leave a come-a-long out for recovery. That's what is pushing me for a "how low can I go" approach to the cart.

I really like what you've got. I've got to see how I can get closer to that.

The steeper the ramp, the sooner the boat will float. If the pictured ramp had been steeper, I think I would have had no problem, even without the tongue extension I've added. And you won't need a 4x4 to get back up the ramp! :D

That assumes the water is at the end of the ramp! at 1/2 low the water is 100' over mud. I'll take some measures this weekend. hopefully I'll get those corners cleaned up too.
