I've been given the option of a pile berth mooring in Dickson Inlet. The authorities think the piles may be 10m apart. Waitui is 7.92m loa. I know she will physically fit between the piles but how do I calculate the tidal range (3.4m max) when deciding how and where to tie her off.
I have never used pile moorings before. Cheers.

You are going to tie up between them, with a meter leeway forward & aft ? I have a bit to do with coming along side pilings and in my experience the vessel overlaps the piles , generally the type of vessels that use them have rubbing strakes to deal with the wear and tear. Also you can use fenders & boards but that's another issue. I digress if you have a sliding ring attached to the piling with a permanent line/s attached to pick up quick and drop over an onboard cleat / bollard
It should work but in that case there's no allowance for springers. Hope I'm overthinking it and it's really easy

Thanks Woko, there are no sliding rings but I have thought about making my own out of rope and floats. I too am going to work on the assumption that it really won't be that difficult. I know very little about the set up (what each pile has on it) but I am going to learn quickly. I sail Waitui up from Cairns on Thursday. I have one day on the yacht club pontoon and then on to the mooring.

Are we going to get any photo's ?

Ones, I needed quickly solved the problem. Used car tyres filled with foam. Close opening with flat rubber and incorporate solid rope.It did work well .

No photos mate. The yacht is in Cairns but I am bringing her north tomorrow. Good Friday I am on the yacht club pontoon and Saturday I will be attempting the pile berth. Maybe a photo or two then
