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.

LAYOUT PLAN EXAMPLE
For an optimal strength and assembling ease, we recommend that you use the same part numbers
or same thickness or size, throughout project. Always use galvanized bolts, nuts & washers:
3⁄8” x 2 ½” for 7⁄16” holes; ½” x 3” for 9⁄16” holes.

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).

For a floating dock section, spread 2” x 6” float supports and floats
evenly on the frame (to evaluate where they will be installed). Mark
the frame and supports (for bolts) accordingly. Remove floats and
screw on the support boards. Bolt on floats to the supports.

You will need help to flip the structure over to avoid any back
injuries. 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"

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! (size may vary)
