No. Remember it's still about speed over the water AND angles, not angles and then speed (my opinion always).

Dump the traveller and/or over sheet the kite.

I have some very rough numbers in my head for the Inter 17 regarding how much higher I can sail if I dump 18 inches and then all the traveller when the kite is up (and in lighter stuff it a fair amount).

You still need as much speed as possible and you should get that from wiring.

there is also the consideration of where you are going next.

If the next leg is a beat or non (no way) kite leg, then I'll let the kite take me deep if I have to, then drop and head up and then be ready for a nice rounding for the tight reach / beat.

If the next leg is another kite leg, then I'll work real hard to lay the mark with the kite up as (if you make it) you can then return to VMG mode and not have to drop and re-hoist the kite at the mark.

IMO sailing with the kite up when wiring is all about having a "grand plan", I try and answer the following q's before I put the kite up for a leg.

1, is it pure VMG (i.e. stay in as much wind and the right shifts)
2, is there any bias on the leg (do I need to sail more Port or stbd?).
3, is the leg after this kite up or down
4, is there much slower traffic on Port or stbd (looking for a clear passing lane)
5, do I need to worry about anyone behind me (are the faster boats that may pass, or do I need to protect my position).
6, do I need to think about phases of regular shifts

Given the answers to the above, a "plan" should present it's self...

1, If it's just VMG (so a pure run) then just go with the shifts / gusts but try not to bang a corner
2, If there is some bias on the leg, will I be on a lift or header when I round - If header and on the short leg, might be best to say on the header working on the principal that it will shift back in time to gybe back, if on a lift on the short leg, then gybe.
3, If so and it's a little tight and I am on a gust, sail high WITHOUT the kite up and then hoist and (hopefully) lay the mark and sail on with the kite up.
4, Passing slow traffic without a good lane can be a PITA, if loads of boats (esp if they don't have kites) - go the other way.
5, If you have people behind you, that you want to keep there, it pays to stay in the same band of wind if you can, they get a gust that you don't, thay can just sail around you and away.
6, On a header at the moment, stay with it. If on a lift, gybe.

All of those are trade offs against each other, and you can only find the answers with time.

It is really usefull to KNOW how much deeper you go for the average "gust" on the course on a day - this may allow you to work out if it's worth gybing on a gust that is a lift (you will loose something in the gybe), or just power off with more wind on the lifting gybe (but still going lower as you have more wind).

This last point is very true where I sail as we only usually have fairly small courses with a W/L of between 1 - 1.5 miles, so if fairly windy, the run may only take a couple of minutes, and so going an extra gybe might only cost you 15 seconds from wire to wire (when I've had some practice <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> ), but that might be 5% of the time on the run.

Hope this helps....
