Hi,

I don't know which sort of races we are talking about. Cutting edge AC  or local amateur club type.

But I think you can shunt HP's pretty quickly.

It would make little diff as long as the legs were not real short.

I always sailed my El solo and so I had a few things to do to shunt. Two sets of sheets, one rudder pull up and then move to opposite side and pull other rudder (new aft on) down.

With a crew of two it could be a very simple slick operation. Someone can be getting sheets pulled in nice and quick and basically the time it takes to do that is how long between moving one way and then moving off on new tack (shunt)

Especially if both rudders stay down.

So for average Joe should be no draw back here.
