Hi.
Just wondering how you are supposed to trim manually without woolies/telltales etc.
Cheers,

The scale on the right side of the screen has two cursors. One of them moves up & down as you trim the sails. In the correct position it turns green.

You can also look at your boatspeed and/or your VMG.
If you trim the sails on and they go up, that's good. If they go down, that's bad... so ease them out again... keep easing until they stop going up... then bring them back on again.
Going faster is better. Going slower is worse. |

Once you have the sail trim in the green you keep watch on the Blue wind direction arrow on your compass. As the wind shifts you must decide whether you 'feather' the sail or 'feather' the boat. By 'feather' I mean trim either the sheeting or the steering.
If you wait for either the color to change or the digital readout of BS or VMG to change then you'll always be too slow in your reactions and your boat will fall behind those who are watching the primary indicator of wind direction change.
Typically when beating to windward you will feather the boat so as to point as close to the wind as possible without losing any boat speed (review the polar diagrams) but when you are not close hauled (e.g. fetching the mark on a reach or downwind) then you'll maintain maximum boat spead by feathering the sail and not the boat.

Also, just wondering how realistic the trimming (e.g. trimming through tacks, pumping down waves etc) is.

No offence taken. But honestly, that's how I learned what worked... by experimentation and observation. I tried something and looked at the instruments and observed the effect. If it made the boat go faster, it was a good thing. If it made the boat go slower, it was a bad thing.
So, when I wanted to know what the answer to:

was, I tried it, and experiemented. There are some comments re. my opinions on tacking and steering through waves etc. in this thread at vsk-aus.com.
