With spinnaker I always try to sail a hull out of the water unless the wind is below 6 knots as Eric says.
You will pick up speed and start to head deeper nautomatically.
-> steer careful when going deeper, otherwise you loose speed + the wind angle changes to fast -> no good flow in the sails.
If possible, even try not to steer and ease the spinnaker and main a little.

Finally play around with your weight.
Crew to leeward and when the wind picks up reposition towards windward and eventually trapping.
Once the crew is on the windward hull, I as skipper sit in the middle of the tramp.
Also weight to front-back is important. As long as we don't pitchpole we move forward. And during the leg we move all the time. Less speed no hull out -> forward, if the hulls comes out -> backward. That's why the crew starts to trap quite fast -> movability.

I've been sailing the Blade now for 2 years and 2 things caused me to evolve the most:

- getting used to the speed downwind -> so you don't overreact with steering
- crew on the wire makes the boat lots and lots more stable -> we haven't pitchpoled eversince!
