H OW T O B UILD a Wooden Dock System Congratulations on choosing Multinautic's® Quality Dock Hardware. A well assembled dock system will bring you many years of enjoyment. Make sure to always use & wear the proper personal protection in order to work securely. Never use electrical tools near water...We want you safe & sound to enjoy your dock for a long time... You can find many other useful tips on our Web Site to help you achieve the project you want. Floating ON ANY DOCK SIZE OR MODEL, THE FOLLOWING STEPS APPLY: 1. Make YOUR "Layout Plan" in order to visualize all the material you will need to do the job (see the examples below.) 2. If you want to change the sizes, just change the proposed lenghts accordingly. Check on web site for more plans. 3. For a floating dock system, look at “ANCHORING SUGGESTIONS”, on the back, to get and install everything needed.

Always use galvanized bolts, nuts & washers: 3⁄8” x 2 ½” for 7⁄16” holes; ½” x 3” for 9⁄16” holes. 4’ x 10’ Stationary 2” x 6” ou 2” x 8” Qty inside corner 10001 11001 4 Back plate 10010 11002 4 Leg holder 10011 11004 2 Base plate or 11107 2 Hinge 13303 11003 2 6’ or 8’ post & PVC cap 2 inside corner 10002 même 2 Back plate 10003 même 4 depending on part types Bolts & nuts 4’ x 10’ 1 A C B Mount the dock upside down on a flat surface in order to easily install floats. The boards need to be flush on the bottom side to install decking properly in last step. Lay down boards, best side out, and screw together. The screws should not be aligned with holes you will make for hardware (A). Check squareness by measuring in “X” from corner to corner (+/- ¼") (B). You can lock the position by screwing down a diagonal piece temporarely on the frame (C). 4’ x 12’ Semi-Floating Inside corner Back plate Hinge Inside corner Back plate Bolts & nuts 2” x 6” ou 2” x 8” Qty 10006 11001 4 10010 11002 4 13303 11003 2 (for joist) 10002 2 10003 4 depending on part types 4’ x 12’ 2 Starting with corners, align parts, mark holes with a pen, drill, then install hardware with bolts.

Mark the frame and supports (for bolts) accordingly. Remove floats and screw on the support boards.

Carefully flip the structure top side up. Lay down, space and screw on decking planks along each side and inside joists. Before you proceed with this step, confirm squareness again. First, look around at your neighbor’s docks and if they have been there for many years and standing well, a similar choice may be good for you. A STATIONARY DOCK should not be installed in a depth of more than 4’ because you’re going to have water over your head during installation. A stationary dock is perfect in shallow waters (think about the water level that can drop during the season). Where you have big fluctuations of the water level, you may start with stationary docks and add floating ones in deeper area. A stationary dock is not designed to withstand lateral pressure that can be caused by a boat moored beside it. It is suggested to moor the boat with concrete blocks and ropes. A FLOATING DOCK SYSTEM absolutely needs an anchoring system at the end of it, and at every +/- 30 feet. Get some: anchor chain holders, anchoring blocks or concrete deadmen, chains, shackles and/or pile guides (or multi-anchoring leg holders). The following formula enables you to determine an average of FLOATATION for a dock “Basic” : 20 lbs / sq.ft “Good” : 25 lbs / sq.ft “Commercial” type : 30 lbs + up / sq.ft +/- 13" +/- 17" +/- 20" Floats’ Height & Buoyancy Capacity 8” / 370 lbs 12” / 450 lbs 16” / 600 lbs * FreeBoard: height of dock above waterline (the example below is calculated with an average of 25 lbs) © copyright Multinautic® 2010 Free Board * BUOYANCY (average per square foot) 1 - Area of an 8' x 12' dock : 8 ft x 12 ft = 96 sq.ft 96 ft x 25 lbs / sq.ft = 2400 lbs 2 - Multiply area sq.ft by average sq.ft buoyancy : 3 Round up to the pair 4 - To confirm the accuracy of your answer...take the total of floats you plan on installing (6) multiplied by its capacity (6 x 370= 2220 lbs of buoyancy) divided by the area of dock : 2220 lbs ÷ 96 sq. ft. =23.125 lbs will be the total buoyancy capacity of the dock to which you need to deduct the weight of the dock itself in order to get the net total floatation capacity...ouf! 5 - Make sure you can fit them all under your dock!
