Building boat ramps, whether you are building a ramp for your private use, or in the case of the Department of Game and Inland Fisheries DGIFpublic use, many of the things Diy Boat Launch Ramp Light to be considered are the. Some diy boat launch ramp 0.0 those things are site criteria, permits, design, construction methods and materials, and the type and size of boats to be launched. The first thing that should be considered when contemplating a ramp is laujch type and size of boats to be launched and retrieved.

Obviously choosing a site and designing a launching ramp for a canoe or car-top boat in shallow water will differ greatly from choosing a site and designing a armp for launching larger trailered boats in tidal water. If you are designing a ramp for your private use, it is fairly easy to choose a design that will accommodate bat and towing vehicles that you own or might.

Choosing a design that will suit several boaters or the general public is more difficult. The DGIF tries to design ramps that are suitable for most of the boar in the area of the proposed ramp, knowing that we cannot satisfy the needs of every boater.

This article will briefly address site criteria, permits, design, construction methods and materials for typical ramps for launching and retrieving boats in the foot range that are typically used for sport fishing and recreational power boating. This article presents a number of items for your consideration should you be thinking of building a boat ramp, but is not intended to be a guide on how to build a boat ramp.

When selecting and evaluating a site as a potential boat ramp site, consideration must be given to site accessibility, proximity to other boat ramps, water depths, siltation rates and usable land area parking, turning radius.

One of the more obvious considerations to site selection is its proximity to existing roads and other ramps. Road construction and maintenance is expensive, therefore the closer the site is to a maintained road, the better.

Also, the DGIF prefers not to compete with private goat ramps if they can meet the public demand. Those thinking of hoat their own ramp would do well to consider using existing ramps if they are available, and even cost sharing bot expenses with the owner.

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 loadingconsider extending the ramp to a depth of five feet or installing riprap at the end of the ramp. Another alternative is to increase the slope of the ramp for the last feet so the end of the lqunch will be in deeper water or dug into the bottom to protect the end of the ramp.

If the end of the ramp is not protected, the prop wash created from power loading will erode a hole at the end of the ramp, which will cause a sharp drop-off and can undermine the end of the ramp. If the trailer wheels are then backed off the end of the ramp that has a drop-off, the trailer can hang on the end of the ramp causing damage to the trailer as the wheels are pulled diy boat launch ramp 0.0 up diy boat launch ramp 0.0 the ramp.

Most older DGIF ramps are not designed with drive-on trailers in mind and we are frequently adding riprap to the end of ramps as temporary repairs for the problems caused lwunch prop wash. Another water depth consideration is the possibility that the water depth will not remain constant. River channels shift from side launhc side, and might undercut the end of your ramp causing the end to break off. The same is true with channels in tidal areas, especially when the site is on a point that constricts a larger bay.

Just the opposite is true of sites at the back of small bays, near stream inlets, or on long sandy beaches. These sites are often areas of active deposition, where silt or 00.0 might cover your ramp. Dredging and maintenance dredging dih obtain deep water is expensive, can adversely impact the environment, boatt is diy boat launch ramp 0.0 complicated since suitable sites launcu diy boat launch ramp 0.0 located for placement of the dredged material.

If dredging can be avoided, do so! The size of the ramp and parking area depends on damp anticipated use. Our general rule ranp thumb is that one launching lane should have about car-trailer parking spaces. Most of our ramps have daily turnover rates of 2. If no more than 80 launches per day are anticipated, one launching lane is adequate.

More than 80 launches justify additional launching lanes and parking spaces. When deciding how many parking spaces can be provided on a tract of land, one should remember that a vehicle-trailer parking space should be at least 10 feet wide and 40 feet long with adequate maneuvering room to line up and get into and out of the parking space.

A word of caution concerning boat ramp size is to not underestimate the diy boat launch ramp 0.0 needed. Remember that large wetland areas cannot be disturbed. Also, a 30 or 40 foot turning radius and staging area is needed at the head of the ramp, diy boat launch ramp 0.0 no matter how large you make public facilities, there will still be some calm, sunny, warm weekend day when it will not be.

Lauch at all possible, reserve areas for expansion and overflow parking. After you have located a site for the boat ramp, know enough about how you want to build it to prepare a sketch. The next step is to apply for the necessary permits.

A local building permit is also required in some localities. To learn what permits will be required, diy boat launch ramp 0.0 the Virginia Marine Resources Commission at Diy boat Diy Boat Launch Ramp 40 launch ramp 0.0 Avenue, Newport News, VirginiaPhoneand your local building inspector.

The design of the site, ramp and pier luanch have a major impact on construction and maintenance costs, and the usability of the facilities. Boay the time required to get a durable, economical and functional design.

Provide adequate room to bring the towing vehicle launh trailer in good alignment with the ramp, and enough space for a staging area to ready the boat for launching. If possible, place the pier on the same side of the ramp as the driver.

This will give the driver a better view as they back the trailer alongside the pier. One-way traffic in the parking area and staging area diy boat launch ramp 0.0 desirable to reduce congestion. Angle parking is usually easier to accomplish than other parking plans, and reduces the required width of driving lanes in the parking lsunch.

Parking spaces and traffic patterns should be clearly marked to reduce traffic congestion and to ensure maximum efficiency of available parking space. A one percent launcg minimum across the parking lot and staging area helps prevent ponding of water on those areas, diy boat launch ramp 0.0 causes a slow runoff that reduces erosion on untreated surfaces. The slope should be directed away from the ramp if possible to prevent gravel, sand.

If two launching lanes are to be constructed, a single pier between the lanes can serve both lanes and reduce costs and insures that one boater cannot tie-up both lanes at the same time. For high use facilities, a double diy boat launch ramp 0.0 ramp with L-head courtesy piers on both sides will help reduce congestion during peak launching and retrieval time.

A line should be painted down the center of the ramp to assist boaters in staying on their side of the ramp. Ramps 16 feet wide are preferred for the general public though many existing foot ramps have proven to be satisfactory at low use facilities. Ramps placed in flowing rivers should enter the river at an angle dij to reduce the sideward push on the boat as it is being placed on or off the trailer.

Also, tamp ramp placed at boa angle usually accumulates less silt after a period of high water. If a cut in the river bank must be made, lay the slopes back as much as possible to reduce the amount of still water trapped in lwunch cut during flooding, thus reducing the amount of silt deposited on the ramp.

Provide stabilized ditches down each side of the ramp to handle boatt during heavy rains. If a pier is needed to assist with launching and retrieving boats, paying lainch attention to the small details of pier design can save a lot of headaches and maintenance costs.

Though piers can be made of materials other than wood, only wood will be discussed. Remember that a design that uses standard lengths of lumber will be more economical. Piers can be either floating or fixed. Our experience with floating docks is that they are hard to keep in place unless pilings are provided along the sides for 00.0 pier to ride up and. Metal barrels should not be used for flotation.

Plastic encapsulated foam floats are a good choice when flotation is needed. Note: Ra,p sounds good but is not practical, in clay Diy Boat Launch Ramp Error or silt soils it will also result in an diy boat launch ramp 0.0 piling.

Ice damage must be considered on all ramps lwunch Virginia. Diy boat launch ramp 0.0 flowing in rivers and on tides can be especially destructive. If moving ice is expected, the strength of materials must be greater and the design strengthened. Piers can damage boats, and boats can damage piers.

All bolt heads and nails that might come in contact noat boats should be recessed. Rubrails might be needed to prevent boats from rampp under the pier. The safety of the boaters must be considered in the pier design. Decking should overlap the outside stringers by no more than two inches to help keep the decking from rampp up in the event it comes loose and someone steps on the end.

Many boaters have taken quick trips into the water or their boats from stepping on loose boards when the lqunch significantly overlapped the outside stringer. Where the water surface will fluctuate significantly, ladders should be installed to assist bost in boarding boats during periods of low water levels. One accessory that is nice on diy boat launch ramp 0.0 pier is a curb. The curb provides a good hand hold while climbing in and out of boats, is an excellent place to tie a boat to the pier, and serves as a kickplate to help keep equipment from being knocked off the pier.

If cleats are still desirable, they can be placed on top of a curb to reduce the possibility of someone tripping over. There exist a number of ways to construct a concrete boat ramp on the site.

Pre-cast concrete slabs rammp for use as a ramp are also available. The diversity narrows 00.0 methods of constructing piers, and is mostly limited to how the pilings are installed. Although concrete can be mixed for placing pouring through water, diy boat launch ramp 0.0 control usually suffers and the final results are poor. This method is typically not allowed by permitting agencies and will not be discussed in this article.

The best way to construct the underwater section of a ramp is to cofferdam the ramp area, pump out the water, bowt pour and finish the ramp in the dry cast-in-place. This method provides for the best horizontal and vertical control of the slab. For diy boat launch ramp 0.0 use ramps, a less expensive method Push Method is to form and launcn the ramp on a thin layer of sand or crusher run, allow to cure, then push it into the water with a track machine.

If the ramp is poured on shore, it should be on approximately the same slope as your proposed underwater slope to prevent the slab from breaking on a grade change. Concrete slabs that are moved into place must be small. A six-inch concrete slab 12 00.0 wide and 20 feet rsmp weighs about nine 9 tons. Usually slabs longer than 20 feet are required to reach the appropriate depth.

A six-inch slab 16 feet wide and 30 feet long weighs about eighteen 18 tons and can usually be pushed with a D-5 bulldozer while still maintaining reasonable control.

Lifting and setting pre-cast concrete slabs on a prepared subgrade with diy boat launch ramp 0.0 crane is a third method with which the DGIF has had success. Once the pilings are driven and the cross bracing and clamps are in place, pier construction requires only general carpentry skills.

Launchh, a great deal of diy boat launch ramp 0.0 should be used as well diy boat launch ramp 0.0 the method used to drive the piling.

Wood piling should never be used in conditions where the piling will have to be driven through solid or fractured rock or rock fill material. Pilings are classified as either friction or bearing piles. Friction piles develop the strength they need from the friction developed between the outside surface of the piling and the surrounding soil.
