Navigating to "xxx.0" TWA
Post by iconPost by Irish Temper | 2020-04-24 | 17:06:49

Hi All,

Sorry if this has already been covered (search function would be great).

I think I've noticed a trend with some of the big name boats and so maybe it's coincidence...

When I use the dashboard and look at another top boat's TWA, a lot of the time I see: 145.0.

On my boat I'm always between .1 and .4 different. ie. 145.3

When I view the polars, the polar indicates for a given set of conditions that 145.0 TWA is the optimum. I see the good guys TWA set to 145.0. I can't get that to happen on my boat and I usually see something like 145.1 - 145.4.

Is there a way to set my boat's TWA to an exact number? Is this a reason why some boats are just sooo fast all the time because they are more often sailing the optimum angle?

Thanks in advance!

That's been already discussed somewhere on the forum.

You can do it with the programmer:

- Set a program 10 minutes ahead WITHOUT TWA lock.
- Lock the TWA
- Check resulting TWA in the dashboard
- If not proper, unlock the TWA and move the programmer a minute or few again.
- Repeat to point 2 until satisfied
- Move the programmer 10 minutes from now. TWA stays locked

Same thing works when programming your next tack. Find the spot where the TWS is integer, lock and slide the time to the correct one.
