I'm currently on the waiting list to get a beach permit in OC, NJ. God only knows how long that will take, So in the mean time I needed to figure out a way to keep the boat on/near the water. I have a 50 linear slip and only use half of it so i started researching dock designs to accomodate the hobie. If anyone else has been looking, I assume you found the same as me.... very little. I did find one picture of a dock in florida for a 21 but not much info about it. I decided to borrow the idea and start designing mine. My design uses 5- 55 gallon plastic drums for floatation which will give you 1100 pounds of displacement at 50% utilization. I intend on covering all of the top surfaces with 3/4" marine plywood and then cover that with marine carpet. I'm estimating I can build this at about $300 which would be a few grand less than the "cube float system". Take a look at the drawing and let me know what you think.
