When should I..

Hi there!
Guys, when should I use a gennoa and a spinnaker/gennaker at the same time?

If you are already flying a kite, using a genoa at the same time will decrease the amount of wind on your spinnaker, which means decrease of power and speed.

Another time to use both is when you are changing from one to the other.

Not the genoa, it's too big. Especially with an assymetrical spinny.

But a working jib? yeah, on a beam reach in light air, or a fairly tight broad reach in moderate air. That's when you still have "sideways" airflow over your sails and the jib can 'fit into' some air the spinny isn't using. Any lower than that and it's "push" air, jib won't help and may hurt.

Welcome to the forum.

When titling a thread, try to consider that one day someone may be searching for that subject.

"when should I" will not help very much.

"genoa and spinnaker at the same time" would be much better.

It depends:

On rig - some boats can fly a chute and foresail at same time, rare design but happens

On angle - wider angles may allow you to have both sail up, the genoa will tend to flop around uselessly

on pressure - lighter air usually needs as efficient sails as possible, the foresail tends to spoil the airflow around a kite. Heavier air one might want to depower the kite.
