I believe these are floats maybe good for making a dock but not 100% sure. They're not in the greatest condition but I'm guessing they could be refurbished I'm pretty sure they'd probably float as is. They're free. They are almost 13 ft long and about 2 and 1/2 ft wide and tall. They are sitting in the driveway at my office with a free sign on them. You'll need a full size truck probably to move them. I'll take this post down once I see they're gone. Check with me if you want current status.
