Asymmetric technique

Realistically with any sailing dinghy that is designed to sail with the apparent wind, which I believe the Weta is designed for due to the flat cut of the sails. Soaking DW like in a traditional boat such as a phantom will be incredibly slow due to the wetted area and having no ability to make the sails deep enough. Therefore, even the lightest wind you will have to sail to your apparent angle. To what angle is a dark science and very much depends on the breeze and the weigh up of sailing extra distance vs speed. Previously mentioned above - there should be some scientific formula but alas not one that is easy to compute on the water and during a race. I would recommend getting some tell tales on your spinnaker as it is almost more similar to a genoa. As with the aim of any apparent wind boat, it is the search for speed and greatest depth and playing this trade off. This usually involves going low in the gusts and painfully heading up in the lulls. Some cheats that can stop you from playing such large angle changes is to try and sail low for as long as possible and when you start to feel that you need to head up sheet on the main and this should prevent some of the angle change. Likewise to help you bear away and sail lower ease main, which gives you the opportunity to sheet it back on. Out of gybes will be painful but the key is to build speed as quickly as possible while also trying to get the wind attachment to the sails quickly. A large head up ensuring that the kite isn't too eased as will stall out and when the power comes on bear off and ease the kite. Otherwise, I think it is all about the feel and the ability to hunt those extra bits of pressure out at all costs! 

Ahh the sweet spot! Yes if you can persuade the RO to set a course which is a wide triangle with the apparent wind ten or fifteen degrees off close hauled on the reaches and the legs long enough to get the sails set, your bum in the corner of the tramp and if you are young and supple enough to get your feet in the straps and your backside out on the windward float, you will go past most things. You will lose ground dragging yourself back into the boat and furling the screacher but you will retain the memory for the rest of the season when every course seems to turn into a Vmg soak.

And yes, the Weta does have a deeper, larger spinnaker but it has to be dropped on the windward leg which requires a second crew member in all normal circumstances. But there are plenty of people who sail two up who might carry both the large spinnaker and the slightly larger square top main. As to booming (or holding) the screacher in the goosewing position - I have tried it but it feels horribly slow. I haven't actually measured the Vmg in that configuration but it might be quite good. And that is really what this thread is all about - do you soak as low as you can at say, 3.5 knots, point up until the boat comes alive at about 6 knots or point up as far as she'll go at about 8 knots. Deploying the sine/cosine table you would be making money at 8knots if you were 120 degrees below the true wind. Oh for a wireless true wind indicator!
