A: Hello Dave, this dock float has a buoyancy of 680 lbs and as stated in the Specification section, it weights 39.4 lbs. Thanks for asking!
A: With the same loading on both the 12" and 16" the push of the current would be equal on both floats because the same amount of the float below the waterline would be the same (length and with of both size float are the same) With the same loading the only difference would be that more of the 16" float would be above the water that the 12". I'd go with the cheaper float.
A: Hello Chancee, A low dock will be more stable than a high free-board one. And it's going to be the anchoring, usually with chains and blocks that can be adjusted at dock level, that will assure the stability. Thanks for choosing Multinautic!
A: Hello JJ Here is an example of how to calculate the number of floats needed. Calculate the amount of floats needeed by multiplying the dock surface area (lenght X width) by 25 (for 25 lb buoyancy capacity per sq.ft). Divide this number by the choosen float buoyancy capacity (i.e. R-750 float has a 750 lb capacity) then round up to nearest pair amount. Make sure that all floats will fit underneath. Examples: 8' x 12' =96 96 x 25=2400 2400÷370=6,4 so, six R-370 8' x 12' =96 96 x 25=2400 2400÷750=3,2 so, four R-750 We hope this helps! Thank you for choosing Multinautic!
A: There are charts online that describe the weight of pressure treated wood. Suggest you do the math to figure out the total weight.
A: Actually you don't fasten them together, each float gets fastened to the dock. Hope this answers your question The Multinautic Team
