The ideal length of a boat ramp is 4.5 m (15' per lane), with a slope of 12% to 15% (7° to 8.5°). This is to ensure that the rear axle of a typical car does not enter the water before the boat is in far enough to be pushed free, and to prevent people from slipping and falling. Concrete ramps should have drainage grooves trowelled into their surface, sloping away from the centre of the ramp, with the foot of the ramp about 1.2 m (4') below the surface at low water. The distance one is willing to travel to a boat ramp depends on the individual, with some people willing to travel up to 42 miles to reach their preferred boating areas.

What You'll Learn
How far do you drive to get to the ramp?
The time it takes to drive to a boat ramp depends on the location of the ramp and the mode of transport. Some people report that their nearest ramp is just a few minutes away, whereas others say that it takes them up to an hour to drive to their nearest ramp. The time it takes to drive to a ramp can also depend on who is going on the trip. For example, one person says that it takes them 10 minutes to drive to the ramp when they are going alone, but up to an hour if they are travelling with their family and need to stop at the gas station.
The distance to the nearest ramp can also depend on the type of boat you are using. One person says that when they had a trailer sailer, they would drive for an hour to get to their nearest ramp, but it would take so long to launch that they would only use it when they were spending the night.
The type of body of water can also determine how far you have to drive to a ramp. For example, one person says that there are a few lakes within driving distance of their home, but only one that they go to. There are more options if they drive for 1.5-2 hours.

How long does it take to get to the ramp?
The time it takes to get to a boat ramp depends on where you are and the mode of transport you are using. For example, one person on Reddit said that the closest ramp to them is 12 minutes away, but the areas they like to fish are 20 minutes away. Another person said that their town's launch is down their street, so it takes them no more than two minutes to get there.
The time it takes to get to a boat ramp also depends on the type of boat you have and the type of vehicle you are using to transport it. For example, if you are using a trailer to transport your boat, you will need to ensure that the ramp is wide enough for you to manoeuvre your trailer safely. A width of 4.5 m (15') per lane is ideal, but don't go much narrower than that. Many trailer boats are 2.6 m (8'6") wide, and many people find it difficult to handle a trailer in reverse with less than a metre of clearance on each side.
Additionally, the slope of the ramp can affect the time it takes to get your boat in and out of the water. A slope of 12% to 15% (7° to 8.5°) is ideal. On a ramp shallower than 12%, a typical car will have its rear axle in the water by the time the boat is in far enough to be pushed free. Any steeper than 15% and people are likely to slip and fall, plus it's hard for front-drive vehicles to get enough traction on steep, wet slopes.

What are the ideal dimensions for a boat ramp?
The ideal dimensions for a boat ramp are as follows:
Firstly, the slope of the ramp should be between 12% and 15% (7° to 8.5°). A shallower ramp will mean that a car's rear axle is in the water by the time the boat is in far enough to be pushed free. A steeper ramp will be slippery and hard for front-drive vehicles to get enough traction on. Concrete ramps should have drainage grooves trowelled into their surface, sloping away from the centre of the ramp. The foot of the ramp should be about 1.2 m (4 feet) below the surface of the water at low tide.
Secondly, the width of the ramp should be wide enough that a boat trailer and a vehicle can fit on it at the same time, with a few extra feet of space on each side for maximum manoeuvrability. The standard width for a single lane on a boat ramp is about twenty feet, where ten feet make up the primary width and there are five feet on each side that act as buffer zones. A width of 4.5 m (15 feet) per lane is ideal, but a bit wider won't hurt.
Thirdly, when designing a boat ramp for rivers, proper alignment is crucial. Your goal should be to create a ramp that points downstream, so boats don’t have to launch against the current, which is dangerous and potentially unsafe.
Finally, if you plan to charge a fee for use of the ramp, it should have a good side dock that floats (or is adjusted) up and down with the water level. It needs to be secured well enough (or be wide enough) to not be tippy. Anything narrower than 1.2 m (4 feet) is asking for trouble, as these will be busy docks with a lot of people on them. The side dock should have hefty cleats, 200 mm (8 inches) or bigger, ideally placed every 2.4 m (8 feet).

What is the ideal slope for a boat ramp?
The ideal slope for a boat ramp is generally between 12% and 15%. A slope shallower than 12% will cause the rear axle of a typical car to be in the water by the time the boat is in far enough to be pushed free. A slope steeper than 15% will be difficult for front-drive vehicles to get enough traction on, and people are likely to slip and fall.
The water depth at the end of the ramp should be no less than three feet during mean low water, though four feet is more desirable. If drive-on trailers will be used, the ramp should be extended to a depth of five feet or have riprap installed at the end. The ramp should be laid at an angle downstream to reduce the sideward push on the boat as it is being placed on or off the trailer. The top of the ramp should gradually meet the surrounding parking or manoeuvring area to prevent bottoming out.

What is the ideal depth for the foot of a boat ramp?
The ideal depth for the foot of a boat ramp depends on several factors. Firstly, the ramp should be deep enough that its surroundings don't shift quickly due to erosion. If the foot of the ramp is too shallow, it will need constant repairs as the surrounding gravel is eroded by prop wash. The depth should also take into account fluctuations in the tide. The top of the ramp should sit above the water level at all times.
The slope of the ramp is also important. A slope of 12% to 15% (7° to 8.5°) is ideal. On a ramp shallower than 12%, a typical car will have its rear axle in the water by the time the boat is in far enough to be pushed free. Any steeper than 15% and people are likely to slip and fall, plus it's hard for front-drive vehicles to get enough traction on steep, wet slopes. The slope should increase more rapidly starting at about 4' from the water's edge.
The width and alignment of the ramp are also important factors. The ramp should be wide enough for trailers and vehicles to fit, with several extra feet on either side to allow people to comfortably manoeuvre their vessels and vehicles.
