Been busy lately with various things but one thing I have managed to do is put the boat in the water.
The first and most difficult part was to install a mooring of suitable size and strength for the boat. I googled about for the various designs and options and the general idea is that the length of rope/chain from the anchor/concrete slab sinker is about 1.5x the depth of water i.e. 10m water, 15 metres of chain/rope.
The other key factor is that the chain from the sinker, for the first few metres is pretty heavy and then the next section of chain not so heavy. The idea being that the weight and combined length of the chains make any pull from the boat to the anchor a horizontal action and effectly dampen the stresses to avoid any snatch on the mooring chain/rope/boat (in a good setup, the anchor is more of a last resort as the weight of the chain should besuffcient to stop the anchor ever being called into action).
So, our boat is about 1200kg give or take and without doing all the maths about how much water the boat displaces and how much the wind may affect it, we went with an anchor that’s a bit like a Bruce anchor .
The anchor weighing between 150 and 200kg, about 4 metres of 40mm chain (another 150-200kg), then about 5 meters of 20mm chain (maybe75-100kg) and then about 8 or 9 metre nylon riser (big rope). Finished off with a nice mooring bouy that has a swivel integral to it’s body (to stop the chain/rope twisting).
How to get all of this to the right place in the bay and drop it off, again googled a few things and this seems to be the way to do it…..
However, not got those on Rum and I wasnt going to pay for one to come over so the initial plan was to take the gear down to the low tide mark and lift it on some barrels (as the tide comes in) and take it out to the right place and drop it off.
Instead, I went for a DIY job that was a little Heath Robinson –
The plan being to put everything on the barge and secure with a single rope. Lay the chain in a way that would let it go out in the correct order and put a bouy on the pickup of the anchor so that a) i can see it on the seabed, b)try to make sure it landed the correct way up.
So once in position, cut the rope and it all drops in the sea nicely!
Pictures tell the story so here goes (not in order as WordPress and Internet Explorer seem to be struggling tonight so they’ll just have to go up in the order they feel like going on!)…..
