Q:What is the exact outside length and width in inches of the two by four foot float drum?Asked on 5/25/2012 by Dave from Westport,Ma.
Q:Are these really 2' wide or will they fit between joists set 2' on center (i.e., they are 1.875' wide)? Thanks.Asked on 5/31/2011 by Anonymous
Q:on the 4ft x 2ft x 12in drum,nothing on it.how meny inches in the water does the drum submerg.Asked on 5/3/2009 by Anonymous from Tulare,ca
A:It depends on the weight of the dock. If it (the dock) weighs more than the water displaced (by the float drums) it will sink. One float displaces 8 cubic feet of water. One cf of water weight 62.4 pounds. If you do the math and want the float to submerge approximately 6 inches it will support 249 pounds less the weight of the float.Answered on 5/31/2009 by Jose from Grand Lake OK
A:Its easy, first go on the Multinautic.com site and all the questions are answered.
to make it easy, the follwoing applies
8" high float ( example 24'' X 48" X 8") = + or - 13" free board, that means from the water to the edge of dock
12" high float ( example 24" X 48" x 12") YOU GET +OR - 17" freeboard meaning 17" from the water line to the dock
16" high float ( ex 48" X 60" X 16") you get = approx 20" from the waterline to the edge of dock.
the buoyancy for a good dock is 25 lb per square ft.
a 8' X 12' dock = 96 sq ft multiply by 25 lb you need 2400 lb
so you need 6 floats of 370 lb buoyancyAnswered on 3/15/2012 by Jim Multinautic from Montreal, Quebec
