Asymmetric

[H4B]

I have an asymmetric, flatter cut . I have very successfully fitted a SELDEN Bowsprit giving me 1.2 m forward of the stem. This A sail pre dates the bow sprit and the luff is about 1.5 m shorter than I reckon it should be( sailmaker this winter) but in the short term is it better to have the sail fully hoisted or the tack hauled close down to the tack. Which is more efficient?

A proper angle for the sheet is most important as the angle between the luff and sheet shapes the sail.
I have an adjustable tack line with 2:1 purchase so I can adjust the tack height depending on the AWA, easier to adjust the tack than the halyard.
When I sail DDW the tack is high and the luff "slack", the sharper angle the tighter the luff.

I would think that i most conditions it is better to have the tack as low as possible = less momentum to heel the boat.

Ease the tackline a few feet when running deep and try to keep the boat flat and the tackline vertical.
The Cork 1720 Sportsboat has a similar issue. They designed the kite too small. So the fly the kite as above.
