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.

Thanks,
Nate

That looks pretty awesome, and by OC you mean Ocean City, NJ?

I'm going to play devil's advocate or a cocky bastard that wants to argue, take your pick.

From what I hear (and it makes sense), a sailboat on a mooring has more wear and tear due to the action of the waves on the standing rigging.

Wouldn't a boat on sitting on a floating dock suffer from the same wear and tear?

I guess the next question though is: Is the wear and tear worth the increased convenience?

Edit to add: BTW, other than the concern addressed above, I like your design.

Most of the wear and tear occurs with the rigging due to the mast slamming back and forth in the waves. On the 16 the rig is normally very loose without the jib is hoisted. If it were me, I'd use the jib halyard to tighten the rig up and prevent the mast from rotating and slamming against the stops while on the dock.

I keep my 16 on the beach mast up all the time. So I don't get the waves, but get the wind on the mast.

I bought the boat mast up last summer, so my plan is to set it up like it was when I bought it. The forestay was relatively tight with no sails, however the jib halyard managed to put it tiny bit tighter than the forestay with the jib hoisted. So I still (at least I think) get the desired effect of the jib acting as the forestay when sailing.

Frat, I'm actually over in Somers Point. M&M Pizza is top notch.

56kz, Where i am, I get little to no wave action even in noreaster / hurricane conditions. I would like to keep the mast up all the time but I do have these concerns in the back of my mind. I think I would be able to raise and lower it from the dock if it turns out i get more waves than i thought. My perception of the waves may change when I'm looking 26' up and seeing the amplified movement.
