how much weight will this support

Asked by: Stanley
the weight supported is listed in the specs. But see the answer regarding the Kayak dock to understand how to calculate how deep in the water it will float (draft) carrying a given weight

I purchased and received a 24x48x12, still new, has not been installed. My question, could I exchange it for the 24x48x8? Ideally I need a 24x24x6

I am willing to pay any additional charges. Please respond.

When floating how many inches are exposed above the waterline?

I want to build a kayak dock and want to decide between 12 inch and 8 inch deep floats. I am leaning toward 8 inch, but don't know if I could use 2 X 6s around the edge. Thinking they may be in the water if the floats sink 2 inches or more into the water.
Asked by: RR
This takes some simple math to answer. Float displaces 8 sf of water. Fresh water weighs 5.2 lbs/sf. at 1" deep. 8 x 5.2 = 41.6 lbs of water displaced per inch of draft. Float weighs 25 lbs. Divide 25 by 41.6 = 0.6 inches of draft with no weight on it. In other words, float by itself draws 0.6 inches of water. If you weigh 200 lbs and stand on the float by itself how much is under water? 200 plus 25 (wt of float) = 225. Divide 225 by 41.6 = 5.4 inches water displaced. Now you need to know number of floats and weight of lumber. For a kayak dock don't over design it. Make it 4x8 using a sheet of 3/4" pressure treated plywood and 2 floats. Bolt it down using fender washers. Strap foam "noodles" (that kids swim with) around edges as fenders using big zip ties found in the HD electrical dept. Or buy or make some other fenders. You are done. It will float drawing less than an inch of water - and draw about 2-3 inches with 2 people on it.

Rated 5 out of 5 by from Home Depot Floating Dock Drum The Dock Drum (actually a box shape) works as advertised. Home Depot had the best price (free shipping) for any dock float I found. The dock float was easy to integrate into my own wood frame / dock design.

Rated 5 out of 5 by from Used for jet ski dock extension- great value! I was looking for a low cost option to extend my jet ski dock to fit another ski on it, and also for something that floated low enough that I could drive it on... This worked great. I got two 24x48x8 floats, ran 3 stringers across the width of my dock, and bolted 1/2 inch treated plywood covered with grey outdoor carpet (like trailer bunk carpet). And added two 2" schedule 80 PVC pipe Guides. Also Vnotched the Plywood for drive on. Attached the whole thing with eye bolts to the existing dock. Works just as advertised. Sinks down perfectly for drive up, and floats up where ski is level when I get off the ski. Whole project cost around 200.00. I have old school Waveblasters (which are indeed a blast) and only weigh 350 lbs./ 8ft long. for bigger skis I'd recommend longer/ thicker floats. A low cost solution for dock floats that are so expensive everywhere else.

Rated 5 out of 5 by from excellent product Robust float drum, flanges facilitate drilling holes safely to jury-=rig its use in older metal--frame rafts. May be a bit cheaper if ordered from the manufacturer but with Home Depot one has a simple return for exchange if you order the wrong size as I did. Fast shipping.
