Anyone got any tips for dealing with restricted room on a swinging mooring. Is there any merit in all tillers being lashed in the same direction. There is approx 0.5 Kt tide.
 
One of the requirements in setting moorings is to ensure that the boats cannot collide. On our club moorings it's possible to observe how boats with differing underwatersections and windage lie differently, some tide rode and some wind rode. I don't believe that rudder angle would get them all to behave the same. There have to be defined limits on length and displacement to pack them in tight. The only time I recall a problem arising was when a sinker dragged - just after the adjacennt channel was dredged. The riser wrapped around another yacht's keel, so had to be adandoned and shortened to keep it out of the way.

On my mooring the biggest problem is when the tide is not running (i.e. it's on the turn). Add some strong wind and lumpy water and boats are facing all directions. The spacing needs to take that into account.

I doubt that having tillers lashed in the same direction would have much/any positive benefit.

I am at the limit of my ( deep water) mooring swinging room and the guy next door is over is and worse still of a much older boat design. The only answer I have found is to leave the boat with her bum festooned with fenders - after all the problem usually occurs in very light winds at the bottom of a neap tide. So impacts are rarely more than light touches
 
I can imagine that one result of a "tillers lashed to stbd" rule would be to ensure that there is a better chance of all - or most - boats at least lying to one side of the trot line thus leaving a reasonably clear passage on the other. Can't immediately see any other useful effect.
 
There is up to 4 knts of tide on my mooring and I am close to shallows on one side, so I shorten my rising chain with three rubber snubbers. I shackle the snubbers on to the chain to make loops which can allow chain stretch to full length if an pressure comes on. This keeps me away from other boats and usually away from the shallows except in very strong winds from the north at low water. Low water holds the greatest risk of boats hitting as there is no flow to keep them in the same direction, each have different windage and their mooring lines are longest.
Some other boats near me use two mooring blocks about a boat length apart and in line with the run of tide; this keeps the diameter of the turning circle much smaller than with a single block. All the boats keep their helms locked in the centre position.

Just being picky but? the issue of the design is not the old, I assume but different keel/ wind-age configuration so you lie differently when there are low or counter acting forces and due to different designs the boats are on different headings..

The there solution if they just touch is to shorten up on your riser/ mooring strops a few inches, it has saved me no end of hassle.

Things I hate in these circumstances is people who use excessively long riser/ mooring strops there by exasperating the problem or leave an outboard mounted raised and sticking out..

When faced with these situations I would have had a quite word with the harbor master to sort the situation...
 
Thanks for the advice so far seems my problem is fairly common. Shorter strops seem to be a simple solution. Some of the strops I have seen in the area are 4 or 5 metres. Is there any advantage in a long strop. Does it reduce shock loading from waves. My experience is a long strop causes chafe on the hull from the flotation buoy and the shorter the better.
 
We spent four years on a swinging mooring on the Crouch and tillers/wheels lashed to starboard was always the rule. Watching as the tide turned it did mean that all the boats on the trot used to turn into the ebb/flood the same way. Exceptions obviously on windy days when wind versus tide considerations had to be taken into account. The moorings were fairly close together but we never had a problem. Quite possibly it was, as suggested above, a method to keep a reasonable space available between the trots to allow access/egress as otherwise adjacent boats on parrallel trots would have all but blocked passage between them. It seemed to work OK whatever the reason.

I used age as a handy dividing line because it is the older designs of boat that is a problem. Though I would not class my boat as an AWB - it most definitely isnt the A bit - it does move at its mooring in much the same way that the vaste majority of modern boats move. The one next to me is a pretty but old wooden boat with low freeboard ( mine is low for an AWB but this is even lower) and I suspect a full length keel. So the wind speed at which it becomes wind rode is was higher than all the other boats round it.

Used to have a swinging mooring up the tamar and at that time I had a Prout cat. Had exactly the same experience there with the old boats whilst the Prout , a bit to my surprise, moved just like the other AWBs. The only modern boat that was wildly different was a french drop keeler that the owner used to moor with keel up and rudder up too. He caused mayhem.

no option to further shorten the strop / riser, and the older gentleman on the older boat isnt interested in shortening his. the harbour master isnt interested and simply refers to the HA conditions of mooring - he's had complaints about this boat from the previous owner of my mooring.
 
If I tie my tiller to either port or starboard the boat sails on its din & ends up doing 360's
I have to tie it dead centre to reduce this
However when i had my Stella on the Crouch one had to tie the tillers the same way otherwise there would be a lot of clashing as we were often only 2 boat lengths apart. Bob Cole would have a quiet word with us if we defaulted
 
I must say I'm surprised that so many moorings are apparently set within the swing of others! If I were on a commercial mooring and had a collision, I would present the mooring supplier with the bill.

One answer to the question of a short strop is to use a chain strop to, ideally, a samson post. The take a nylon rope with a chain hook from the bight of the chain back to the genoa winch. That should act very nicely as a snubber and the chain will still take the load should the nylon part.
