AntarcticPilot's latest activity

Although it's much less pronounced than in the Antarctic, the ozone layer is depleted in the Arctic too, so UV increases as you head...

And regrettably there have been several incidents reported here where things went wrong. Some were fatal. Personally I am not inclined...

That's the point. The examiner is certifying about 100 different points. Obviously, if the examiner knows the pupil, it may be possible...

I did it with a day's own boat tuition from East Anglian Sea School at Suffolk Yacht Haven. They have quite a lot to check, so even just...

It's worth noting that some boatyards prohibit anyone but themselves from altering supports. I've encountered that condition.

Another factor is that the pure, gravitational tide only occurs in the middle of oceans in deep water. That tide is not very great - I...

I'd also note that free surface instability is very evident if you get water in them - I've had an involuntary bath as a result of that!

I need to get a new oil extractor, and I want the vacuum type; I've used that type before and it worked well. However, there seems to be...

But do they have excellent geodesists? The mathematics is not difficult - I couldn't do it if it was ☺️

Using an equal area grid would not confined you to a limited area; there are plenty of whole earth equal area projections, and...

And isn't parametric rolling (or something like that) a thing too, where the wave pattern and the ship's form combine so the rolling...

I have discussed the use of grids defined on Plat Carree projections (i.e. x =longitude, y=latitude) with modellers several times...

My device was top of the range about a year ago. If you're getting better accuracy than I in a place like Hong Kong, your device is...

First of all, GPS has failed many times; it is actually not at all uncommon. It is routinely jammed in some areas for military exercises...

Sure, but if the OP had glass and resin available, why would he be asking about filler? Better to do it properly by bevelling the holes...
