How many will you have on board?
We fly our kite with 2 up in light (>10 kts) and no auto pilot. It takes a bit of organization on the set and the douse and a little planning for the gybes. 3 up makes it a lot easier.
especially on your larger boat.
With 2 up -
crew 1 = Helm
and spinnaker trim. We have a tiller so it usually means the helm
is between the knees on the set and steering
on the gybe. Spinnaker halyard
on the drop. If you have an auto pilot that really can help.
Crew 2 = Main trim, spinnaker hoist, genny furl. Spinnaker pole on the gybes. Unfurl genny initial genny trim and spinnaker collection on the douse straight into the forward hatch
Once it is flying it is easy. As Sari Says don't go too deep, but also make sure you go deep enough to fly the spinnaker in front of the boat, especially on the hoist.
15-20 off DDW is about right. The genny will help mask the spinnaker during the hoist so it doesn't fill to quick. Pole forward after the spinnaker is made and pole back will expose the spinnaker to the wind and it should fill right up. Once you start the hoist, get it right up and don't dally.
A partially hoisted and filled spinnaker can be a handful for 2 people. If you get partially hoisted stay deep, and guys and sheet off (even if you have to let it do a flyer), do not submit to the tendency to reach up or immeditely drop it. That will make things worse.
I am not trying to alarm
you - this is not that hard but it is a big sail, hard to reach, with a lot of potential power.
The ultimate bail out should it be (remotely) necessary will be something like dropping the spinnaker in the water
and cutting the halyard
. If you do this it is very important to bear up a bit and not drive the boat over the spinnaker. But don't worry - that won't happen..
