James,
We are using tested black iorn chain here. we do get a bit of electrolitic but not much, we had one bad case last year but thats it.
So do you use all galvanized fittings?

Nick

Hi Nick
We use all galvanised or black iron fittings only stainless is after a rope strop if needed. It munches the chain too fast otherwise.

Give him enough rope....

What was that you were saying about allowing enough rope for the rising tide?

Fish box mooring

Hi guys

An idea I have seen work very well is to use a fishbox filled with concrete as a mooring. Place some steel rods in the box, attatvh a length of chain so that some is protruding to provide a connection point. Let concrete set for a fews days and set in pairs. The concrete can be left in the box to help handling.

Best of luck.

Great idea! In regards to the chain, do you just drop plenty of it into the box? How much would a fish-box of contrete weigh?!

old engine fly wheels (big) are about the best sinker you can get as they will suck into soft bottom types.
Trinity house use a round disc which has a concave bottom which aids suction.

we use a sinker linked to a heavy ground chain connected to a smaller riser chain to a bouy and then your top gear (strops) on a bouy.

A proper swinging moorings should take any snatch from the boat by slowly lifting the chain off the bottom.
I use 24mm nylon strops (5000+kg swl) which will take some snatch out in itself.
I was told of a test on a moorings using a 45 foot boat with a tensile gauge on the strop and even in a gale the boat never actually pulled more than 3000kg.

Cahin / concrete

Alt,

where I have seen it done some lengths of steel reinforcing were intertwined in the box and the chain wrapped around them. About one foot was left protruding.
When the concrete set it seemed to keep it all together. Leaving the whole thing in the fishbox would, I prresume, make it stronger.

Best of luck

swivel swivels and swiveles

make sure you use swivels, because chain shortens as it twists as my mate found out a few years ago off Abersoch, nose in first and down it went !!

Andy

but its ok as he's a Yachty !!
