I am on a trot mooring and I was wondering what is an ideal spacing between bouys are. My boat is 24ft and the space I have to get in is about just over 25ft. Makes it very interesting to get back in

Our trot mooring has a designed spacing of 20 Metres between boats. Spacing is a problem as what people are SUPPOSED to do is measure the distance between their cleats - fore and aft - and make the strops to the bouys at either end plus the length between cleats equal 20 metres. Whats some boats actuallydo is tighten their strops to stop their bat from swinging about at low water. This means that I have to winch my boat off my strops someimes, as the whole trot is too tight.
Doesn't answer your question except to say that our 20 metre spacing was designed for 10 metre boats! Much less and you start hitting the bouys at one end or the other at low water.

The spacing of my trots is approx 11m, and thats for a 6m boat. Personally I would not be happy with only having a foot to play with.... I would say the mooring company is putting you on a mooring designed for smaller boat.... check the others on the trot.

We are 26ft on a 30ft trot. But I am on the end so I generally have a lot more to play with.
In your case I would suggest you are to big for the mooring. Before this mooring we were on a 50ft trot and in the middle of the run, that was a nice space to get in. I would not like to go under 30ft personally.

I'm making this up as I go, but I would say the amount of extra room should depend on the tidal range, such that, if at low tide, the wind was against the tide, and your boat is moving with the wind, and your neighbour's with the tide, you're not going to touch.
(i.e. you'd want extra space of just under twice the maximum tidal range)
Even without any tide, I'd want a good couple of boat lengths.

I have seen plenty of close arrangements, though yours sounds a bit tight to call. Clearly with the relatively small tidal range in Poole Harbour (if that is where you are), then there won't be loads of slack at low water. What is your depth at HW and LW?
A side issue would be whether the buoys are tethered together when unoccupied by a lazy line, and what the length of your neighbouring boats are. Is the 25 feet determined by your own lazy lines?

I think you have it the wrong way around.
If the trot is tight there is less chance of the boats coming together. If the boats are pinned fore and aft they can't swing at all?
I maybe get up say 10ft swing out from centre, there is no way she could come around onto a neighbour.
The worst condition is when empty moorings are not strapped up, then the boats left can move in a longitudinal way.

the max tidal range in Poole Harbour is about 5ft from memory...ie not a lot!
maybe as little as a foot on neaps.
there are certainly some areas where the expectation seems to be that boats 'fit the gap'........... /forums/images/graemlins/crazy.gif

well Duncan without naming the place you know where I mean. These must be some of the worst trot moorings around. I have complained to no end. There seems to be more bouys in now so less room for boats. So general consesus is mine are too small for my boat.
