(From the post about true and apparent)
What do you guys do with it?

Only use apparent on my boat, though do a rough calc to get approx true for the log. Only 2 uses for accurate true:
1) Met observations (more big ships than us)
2) Racing yachts: determining polars and sailing for optimum speed

There is a third.....
Bragging about what wind speed you experienced while out on Saturday......

Being a bit of a Luddite, I go for the tell-tales option myself. For wind strength I use Admiral Beaufort's tables. Though it's not often you see a fishing smack these days.

I dont like the look of being on cable ships either - they seem to be out in nasty weather

Mrs G makes a decision whether we go out or not, sod it!

Re: I wonder at it\'s value.
Is a guestimate not good enough?
How is precise wind strength and direction obtained from these instruments?
Where do consistant winds blow?
True or apparent. Who cares?
What decisions do you typically make based on wind info from such machines?

Tome,
Surely we only work from apparrent, dont we? That's what affects the boat.....

Or am I wrong again??

Not really except for the racing boys. They derive polar diagrams of true wind angles and speeds for different wind strengths. Initially, they may use manufacturers published data, then tune it to their own boat performance as they develop new sails etc. All things need to be equal so they go for true wind when doing this.
Whilst they sail, they are constantly checking their performance against the polars to make sure they are sailing at optimum speed and trim/steer for best performance. Having said that, I haven't raced for many a year so stand happy to be corrected.
