Hello everyone,
My first post!
The below might help explain why it is best practice to have a length of chain.....
For an anchor to "hold" it requires a horizontal pull along the bottom of the waterway. Ideally you would have enough anchor "line" paid out to allow for roughly three times the depth of water. The third of the paid out line nearest the anchor needs to be laying on the bottom, to provide the horizontal pull at the anchor stock. Having chain in this section helps considerably, as it tends to lay on the river bed.
The effectiveness of an anchor is dependant on this deployment. They are designed to dig in harder, the more horizontal pull is provided.
A small anchor, correctly deployed on a correct length line, with a chain length to the anchor stock, will be many more times effective than a heavy anchor on a short line, or one that does not have a suitable amount of chain to ensure the pull at the anchor is along the sea or river bed.
The above will also underline why its preferable to have a rope that has least tendency to float.
Best to be clear on the above, as when you deploy this piece of equipment it is often to because things are not going well, and to find it doesn’t work will only add to the likely depression caused by what has already turned out to be a rather bad day!
There may be times when you need to lift the anchor , or detach yourself from it, and if the boat has been riding hard against the cleat it can be extremely hard if not impossible to undo the rope. Practice on many rivers when this occurs is to tie a plastic can or float onto the line, with a suitable knot (check a knot book....it will show you the one to use!) and then cut the rope at the cleat, allowing the float to support the suspended rope. The rope will remain visible, tied to the float and it then enables the anchor to be recovered at a later date or when conditions permit, if this is practicable.
And finally, a stern anchor needs to be used with EXTREAM caution, and can be very dangerous. If when you venture out on a tideway or river you feel releasing the anchor from forward is not going to be possible, then consider bringing the anchor aft to the steerers position , with the end still secured to the fwd cleat , so that it can be deployed aft, but will hold the craft from fwd. Remember to "pay" out an anchor. a bundled coil of rope and chain wrapped around an anchor wont work well...and as for "throwing" the anchor overboard......as one who rather shamefully admits to having followed it over the wall when attempting to deploy by this method, I would suggest that whatever the emergency that requires you to use the anchor, keep your cool, and deploy with caution. If you are going out on river, then practice using you anchor before you go...after all, you will ensure that all your other boat skills are up to scratch before you leave...Surprising how many people have a boat, but have no idea how they would use an anchor if they really needed one!
Tha must enough on anchors...hello! hello!...... any one still awake...?
