Roll-n-Go 4200 Rail System is for boats weighing up to 4200 lbs. (Model #RNG42)
Roll-n-Go’s Model 4200 Railway System is for boats weighing up to 4200 lbs. It has been engineered for strength, durability and simplicity. It is a ready-to-assemble marine boat rail system that is constructed of marine grade aluminum and includes stainless steel fasteners.
The boat rail kit comes complete with detailed, easy-to-follow assembly instructions. It assembles with common tools in a few hours.
Choose from 4 winch options (electric & manual options). The fully adjustable standard bunk system is also upgradable to bunks that accommodate inboard drive ski/wake boats or pontoon boats.
The rails are 4″ high structural “c” channel. The basic kit comes with (3) 9 ft. track sections. Extra track sections, leg kits and angle kits are available to get your boat over rough terrain or to change angles to follow the contour of your shoreline.
The sections connect easily with specially formed brackets and Roll-n-Go has incorporated a carriage retaining system to prevent the carriage from accidentally getting knocked off the track or from rolling off the end.
The carriage contains 2 fully welded ends connected by bolt-in channels. It will accommodate any of our fully adjustable bunk systems.
The wheels are machined from solid aluminum, with bronze bushings that ride on greasable, grade 8 axle bolts for many years of smooth service. The carriage has sturdy PVC drive-in guides that adjust to 112 inches wide, over 9 feet.
The Model 4200 is a great place to store your boat over the winter on shorelines that are not subject to ice floe surges. Just winterize and cover your boat and wait for that first warm and sunny Spring day to get back onto the lake!
Roll-n-Go 4200 Rail System Options
How far into the water does the track need to go?
The track needs to go to a water depth of 2 feet (28 inches deep with the “high bunks”) plus an additional 10 feet. If your lake fluctuates, take into account low water levels.
Will I need extra track?
The basic Model 4200 comes with about 24 feet of track. You may need to order extra 8 foot lengths if any of the following conditions exist.
The slope of your shoreline is very shallow or flat.
Your lake level varies throughout time.
Your boat is longer than 17 feet.
Your boat has a deep draft.
You choose to pull your boat farther for any other reason such as to a boat house.
Complete the following to determine the minimum track length you will need.
1) DETERMINE LENGTH OF TRACK THAT IS IN THE WATER WHEN LAKE IS AT LOWEST LEVEL. FIRST, FIND THE LOCATION WHERE THE FRONT OF THE CARRIAGE WILL NEED TO BE. THAT LOCATION IS WHERE THE CUR- RENT WATER DEPTH IS EQUAL TO THE SUM OF THE FOLLOWING 3 VALUES:
The draft of your boat.
20 inches if using regular or pontoon bunks and 24 inches if using the high bunks (ie for inboard motor wake boats or ski boats)
The difference between the current water level and low water level.
NOW, FROM THAT POINT MEASURE TO THE WATERLINE AT LOW WATER LEVEL AND ADD ANOTHER 10 FEET. THAT WILL BE YOUR “IN-WATER” TRACK LENGTH.
2) DETERMINE THE MINIMUM ON-SHORE TRACK LENGTH AT HIGH WATER BY COMBINING THE FOLLOWING 3 VALUES:
Boat/motor overall length PLUS …
Buffer or walk-around space behind the boat, MINUS …
Front overhang.
The bow of most boats will overhang the front end of rails and winch by at least 2 feet and most pontoon boats can overhang by 3 or 4 feet with the following exceptions:
When using a manual winch with post, subtract 0 overhang feet and add 1 foot to required on-shore track length.
Tri-toons subtract 0 overhang feet and add 1 foot to required track length.
3) FINALLY, MEASURE THE DISTANCE ACROSS THE GROUND FROM THE LOW WATER LINE TO THE HIGH WATER LINE.
ADD THE RESULTS OF STEPS 1, 2, AND 3. THIS IS THE MINIMUM LENGTH OF TRACK YOU WILL REQUIRE.
DIVIDE BY 8 TO DETERMINE THE NUMBER OF TRACK SECTIONS NEEDED. 24 FT COME WITH THE MODEL 4200 KIT AND ADDITIONAL SECTIONS ARE SOLD IN 8 FOOT LENGTHS.
NOTE ABOUT HIGH AND LOW WATER MARKS:
Consider choosing high and low water levels that are realistic for a 10-15 year time frame to reduce the number of sections required. In the event of a very extreme our systems can be moved and track sections added to. Obviously, the high and low water spread can significantly affect the length of your system.
Flat sloped shorelines will add length as well because the minimum low water depth will be farther from shore.
The “high bunk” option can add 2-4 feet of length
A WORD ABOUT WINCH CABLE LENGTH
Your winch cable length can be 10—12 feet shorter than the total track length since it only needs to reach the top end of the carriage and in most cases, when the boat is on shore, it can overhang the front of the ramp.
Bunk Options
Bunks available for Model 4200
Roll-n-Go Offers 3 bunk sets for use with the Model 4200 Rail System.
Bunk Option 1 – Standard Bunk Set
The standard bunk set which comes at no additional charge is the Multi Hull Bunk set. This system will adapt to most hulls whether V-hull, tri-hull or flat bottom boats. It consists of 4 pads of quality marine grade carpeting securely fastened to pressure treated 2 x 10 lumber. The easy mounting system gives you many options for location and angles.
Bunk Option 2 – High Bunk Set
The High Bunk set is identical to the Multi Hull set except its taller brackets give the clearance required for many inboard drive and v-drive boats common on ski and wake boats, and others with tracking fins.
Bunk Option 3 – Pontoon Bunk Set
The Pontoon Bunk set is ideal for boats with round pontoons from 19? to 27? diameter. They can be use with tri- toons, even if the center pontoon is a larger diameter. (The center pontoon will not be supporter but will hang free with plenty of clearance). These bunks are constructed with marine grade carpet mounted to pressure treated lumber.
Winch Options
Winches available for Model 4200
The winch you choose will determine which winch mounting plate or winch post you will receive. For the top end of the track. Extra track sections, leg kits and angle kits are available to get your boat over rough terrain or change angles to follow the contour of your shoreline. The carriage contains 2 fully welded ends connected by bolt-in channels. It will accomodate anyy of our bunk systems (sold separately). The bunk mounting system allows you to locate them anywhere along the width of the carriage and adjust the angle of the bnk to fit your hull perfectly. The wheels are machined from solid aluminum, are double flanged and bronze bushings that ride on greasable axle bollts. The carriage has strong, PVC drive-in guides that adjust as wide as 9 feet. It is also equipped with a retaining system to prevent the carriage from jumping the track.All electric winch options include an aluminum winch/motor cover.
