FLOATS
Your use of the dock and your boats will guide you in choosing the oat model you need:
• For swimming, pedal boating, canoeing or kayaking: low free-board
• For a pontoon or large motorized boat: high free-board
To calculate the amount of oats needed (for residential use) :
› Multiply the dock area (length x width) by 25
(for 25 lbs buoyancy per square foot).
› Divide this amount by the buoyancy capacity of the chosen oat (ex. oat R-750 has a capacity
of 750 lbs) then round to the nearest even number.
Examples:
low free-board 8' x 12' = 96 pi
2
96 x 25 = 2400 lbs 2400 ÷ 370 = 6,4 oats so 6x the R-370 model
high free-board
8' x 12' = 96 pi
2
96 x 25 = 2400 lbs 2400 ÷ 750 = 3,2 oats so 4x the R-750 model
› Make sure you have enough space to install all oats under the dock.

Float supports should be
placed perpendicular to the
length of the dock. Adding
corner reinforcements and
back plates will make the
dock more sturdy.

To add a nishing touch and protect
your boats, install dock bumper
with truss head stainless steel screws.

To add sturdiness to a
oating dock, you can
screw wooden braces in
the four corners, in which
you will also screw the
decking.
