A Meditation on servicing Winches
Well hi there, shipmates. I’m not quite sure what a literary meditation should look like (or read like?) but here’s what I thought when I was servicing the starboard sheet winch. What’s a winch, I hear? It’s a big hunk of metal full of moving parts, large and small – an assembly of cogs, shafts and bearings, and tiny bits called er, I forget what they’re called but they are extremely important! Wait a minute, I’ll look it up – yeah, ‘pawls’. And what does it do? It is a modern day replacement for block and tackle. It’s shaped like an old-fashioned cotton reel, with flanges top and bottom. You wrap a rope around it 3 times, clockwise, put a pull on it so there’s some tension, pop a handle thingy in the hope at the top and wind away. As if by magic, sails are lifted, jibs sheeted. Ours even go at 2 speeds (different amounts of mechanical advantage, like bike gears). And once a year they need servicing.
When we bought Snork Maiden I was so terrified of the job that I didn’t do it all the first year. The second year I convinced myself of the necessity, photocopied the relevant bit of Nigel Calder’s Boatowner’s Practical & Technical Cruising Manual (sic), put it in a plastic ring binder and got to it. It’s actually one of the most enjoyable jobs on the boat. The parts are beautifully engineered in bronze and stainless steel, and they appear remarkably simple. But the really amazing thing is that the really chunky, heavy-duty parts are held together and operated by tiny things. The clip that secures the whole thing only weighs a couple of grammes, and the pawls are held in by hair-like springs that a small butterfly could lift.
All the bits have to be cleaned in lamp oil to clean off the old grease – I use an old toothbrush. There’s something very satisfying about this. Then re-assemble with brand new winch grease, applied delicately with bare hands (I wear gloves for the lamp oil bit) to the cogs and bearings. Now comes the tricky bit, putting back the pawls in the right orientation and without the tiny springs leaping overboard. Now I am on my 5th season of winch maintenance, this bit goes a lot faster than it used to, and I haven’t lost one overboard for a quite a while.
The whole thing takes me an hour for the first one and probably about 10 minutes for the 4th! The spinnaker winches are hardly ever used, so they only get the treatment every couple of years. I think this might be one of those years.
Well, this was written because a thunderstorm stopped play! It’s still very hot, but now humid as well. Totally tropical.
PS Recently discovered fact about winches: the standard winch derives from helicopter gearboxes a similarity spotted by a farsighted chap called Henry Shepherd in 1959.
