Ramp Slope A slope of 12% to 15% (7° to 8.5°) is ideal.8 nov 2012
How deep should a boat ramp be?
Water depth should be no less than three feet at the end of the ramp during mean low water, though four feet deep is more desirable. If drive-on trailers will be used for launching and retrieving boats (power loading), consider extending the ramp to a depth of five feet or installing riprap at the end of the ramp.

What is the ramp on a boat called?
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water.
How steep should a boat ramp be?
The slope of the boat ramp should be steep enough to launch the boat without the vehicle entering the water. Generally, ramp slopes from 15 percent (1.5 feet of drop over a 10-foot length) to 12 percent ensure that boaters will have little trouble launching or pulling their boats from the water.
What's the best angle for a boat ramp?
The ramp angle should never exceed 30 degrees (67– percent slope). An angle of 20 degrees (44–percent slope) is too extreme for some users. The maximum slope of a ramp should be 1:12 or less (8.33 percent) to meet accessibility guidelines.
How thick should a boat ramp be?
This requires a slab at least six inches thick. For ramps where larger boats (over 20 feet) or heavy equipment might be launched, thicker concrete, larger steel and/or stronger concrete might be in order. Concrete should be finished with a surface rough enough to provide good traction, even when covered with algae.
