Just returned from a few days in Queenstown, New Zealand, where they refer to themselves as 'The Adventure Capital of the World'. For a smallish tourist town with a population of only 25,000 approx. they certainly boast a myriad of, not only outdoor, but extreme outdoor activities so their claim is not without substance.
In one of the most beautiful settings in the world, it is seething with folks young and old from all corners of the globe. they want to sample and experience their own personal adventures, be it the usual tourist sightseeing tours or the extreme adventure variety. These range from skiing, snowboarding, bungy jumping ( several variations), white water rafting, para jumping off the mountain, Jet boating in the famous Shotover River, rock climbing, abseiling, cable slip riding, tandem sky diving and others that will thrill the blood of folks of all ages.
You may be wondering what this has to do with sailboat cruising? Not a lot really except that there is one cruise that I took that illustrates most clearly the benefits of well maintained machinery and in particular, engines.
The TSS Earnslaw cruise across the lake to Walter Peak farm station, on a fine sunny day is a delight. You are carried across on the steamship TSS Earnslaw, a one hundred and two year old steamer. She is immaculately maintained with all woodwork, bright work and brass fittings gleaming.

Today she is licensed to carry only 389 passengers/tourists and no sheep or cattle!
From the height of one of the surrounding local peaks she appears to be crawling across the lake like a small black beetle, but in fact she is cruising along at a handsome 12 knots!
|Looking astern toward Queenstown with NZ ensign|
Being coal fuelled she has two doors per engine through which the stoker manually shovels one ton of coal per hour ( you can see that in the video). Hot work down their where the temperature is forty degrees Celcius!
In these environmentally conscious times she even has a large vacuum device built in to suck up the coal dust and noxious fumes from combustion.
Here we come to the point of this post. All cruising sailboats have a motor, which most of us wish only to turn on for leaving and entering port, motoring in a prolonged calm or in an emergency. However, when we go to turn the key or press the button we want to know that she is going to leap into life and perform to our requirement at that time.......and every time!
|Now, there's a windlass!|
The TSS Earnslaw is a model to take example from. She still has her original engines and working today fourteen hours or so, they are running as smoothly as ever they were over one hundred years ago.
